1 General
The devices have sensorless current vector control with a wide range of settings. In combination withsuitable motor models, which always provide an optimised voltage/frequency ratio, all three-phaseasynchronous motors that are suitable for inverter operation and permanently excited synchronous
motors (IE4, IE5+) can be driven. For the drive unit, this means very high starting and overload
torques with constant speed.
The power range is from 0,37 kW to 3,0 kW.
The device series can be adapted to individual requirements by means of modular assemblies.
This manual is based on the device software as stated in the version list (see P707). If the frequency
inverter uses a different software version, this may cause differences. If necessary, the current manual
can be downloaded from the Internet (http://www.nord.com/).
Additional descriptions exist for optional functions and bus systems (http://www.nord.com/).

Safety, installation and application information

Before working on or with the device, please read the following safety instructions extremely carefully.
Please pay attention to all other information from the device manual.
Non-compliance can result in serious or fatal injuries and damage to the device or its surroundings.
These safety instructions must be kept in a safe place!
1. General
Do not use defective devices or devices with defective or damaged housings or missing covers (e.g.
blind plugs for cable glands). Otherwise, there is a risk of serious injury or death from electric shock or
rupture of electrical components, e.g. high power capacitors.
Unauthorised removal of covers, improper use, incorrect installation or operation causes a risk ofserious personal injury or material damage.
Depending on its protection class, the devices may have live, bare, moving or rotating parts or hot
surfaces during operation.
The device is operated with hazardous voltage. Dangerous voltage may be present at the supply lines,
contact strips and PCBs of all connecting terminals (e.g. mains input, motor connection), even if thedevice is not working or the motor is not rotating (e.g. caused by electronic disabling, jamming of thedrive or a short circuit at the output terminals).
The device is not equipped with a master mains switch and is thus always live when connected tomains voltage. Voltages may therefore be connected to a connected motor at standstill.
A connected motor may also rotate if the drive is disconnected from the mains and possibly generate
hazardous voltage.
If persons come into contact with dangerous voltage such as this, there is a risk of an electric shock,which can lead to serious or fatal injuries.
The device and any power plug connectors must not be disconnected while a voltage is applied to thedevice. Failure to comply with this may cause arcing, which in addition to the risk of injury, also may
result in a risk of damage or destruction of the device.
The fact that the status LED or other indicators are not illuminated does not safely indicate that thedevice has been disconnected from the mains and is without voltage.
The heat sink and all other metal components can heat up to temperatures above 70°C.
Touching these parts can result in local burns to the body parts concerned (cooling times andclearance from neighbouring components must be complied with).
All work on the device, e.g. transportation, installation, commissioning and maintenance work must be
carried out by qualified personnel (observe IEC 364 or CENELEC HD 384 or DIN VDE 0100 and
IEC 664 or DIN VDE 0110 and national accident prevention regulations). In particular, the general andregional installation and safety regulations for work on low-voltage systems (e.g. VDE) must becomplied with, as must the regulations concerning correct use of tools and the use of personal
protection equipment.
During all work on the device, take care that no foreign bodies, loose parts, moisture or dust enter orremain in the device (risk of short circuit, fire and corrosion).
Further information can be found in this documentation.
Triggering of a circuit breaker
If the device is secured by a circuit breaker and if this was triggered, this may indicate that a residual
current was interrupted. A component (e.g. device, cable or plug connector) in this circuit may havecaused an overload (e.g. short circuit or earth fault).

BU 0870 en-4622

13

NORDAC ON + / FC1000 – Manual with installation instructions
A direct reset of the circuit breaker may lead to the circuit breaker not being triggered afterwards
although the fault cause is still present. As a result, any current flowing into the fault location may
cause overheating and ignite the surrounding material.
After each triggering of a circuit breaker, all live components within this circuit must thus be visuallychecked for defects and flashover tracks. Also check the connections at the device’s connection
terminals.
In case of no faults found or after the replacement of the defect components, switch on the power
supply by resetting the circuit breaker. Carefully observe the components keeping a safe physicaldistance. As soon as you observe a malfunction (e.g. smoke, heat or unusual odours), the occurrenceof a new fault or if the status LED on the device does not light up, switch off the circuit breaker
immediately and disconnect the defect component from the mains. Replace the defect component.
2. Qualified specialist personnel
Within the meaning of this basic safety information, qualified specialist personnel are persons who arefamiliar with the installation, assembly, commissioning and operation of the product and who have thequalifications appropriate to their work.
In addition, the device and the accessories associated with it must only be installed and commissioned
by a qualified electrician. A qualified electrician is a person who, because of his/her technical training
and experience, has sufficient knowledge with regard to••

switching on, switching off, disconnection, earthing and labelling of electric circuits and devices,
correct maintenance and use of protective devices according to specified safety standards.

3. Intended use – general
Frequency inverters are devices for industrial and commercial systems that are used to operate threephase asynchronous motors with squirrel-cage rotors and Permanent Magnet Synchronous Motors –PMSM (IE4, IE5+). These motors must be suitable for operation with frequency inverters, other loads
must not be connected to the devices.
The devices are components intended for installation in electrical systems or machines.
Technical data and information for connection conditions can be found on the rating plate and in the
documentation, and must be complied with.
The devices may only be used for safety functions which are described and explicitly approved.
CE-labelled devices meet the requirements of the Low Voltage Directive 2014/35/EU. The statedharmonized standards for the devices are used in the declaration of conformity.
a. Supplement: Intended use within the European Union
When installed in machines, commissioning of the devices (i.e. commencement of proper use)
is prohibited until it has been ensured that the machine fulfils the provisions of EC Directive
2006/42/EC (Machinery Directive); EN 60204-1 must also be complied with.
Commissioning (i.e. start of intended use) is only permitted if the EMC directive (2014/30/EU) is
complied with.
b. Supplement: Intended use outside the European Union
The local conditions of the operator for the installation and commissioning of the device must becomplied with at the usage location (see also “a. Supplement: Intended use within the European
Union”).

Wiring guidelines

The devices have been developed for use in an industrial environment. In this environment,
electromagnetic interference can affect the device. In general, correct installation ensures safe andproblem-free operation. To meet the limiting values of the EMC directives, the following instructions
should be complied with.
1. Ensure that all devices are securely earthed to a common earthing point or earthing rail using shortearthing cables with a large cross-section. It is especially important that each control unit which isconnected to the electronic drive technology (e.g. an automatic device) has a short cable with a30

BU 0870 en-4622

2 Assembly and installation
large cross-section, which is connected to the same earthing point as the device itself. Flat cables(e.g. metal clamps) are preferable, as they have a lower impedance at high frequencies.
2. The bonding cable of the motor controlled by the soft starter should be connected directly to theearthing terminal of the associated device. The presence of a central earthing bar in the control
cabinet and the grouping together of all bonding conductors to this bar normally ensures safe
operation.
3. Where possible, shielded cables should be used for control circuits. The shielding at the cable end
should be carefully sealed and it must be ensured that the wires are not laid over longer distances
without shielding.
4. The control cables should be installed as far as possible from power cables, using separate cableducts, etc. Where cables cross, an angle of 90° should be ensured as far as possible.
5. Ensure that the contactors in the cabinet are interference protected, either by RC circuits in thecase of AC contactors or by free-wheeling diodes for DC contactors, for which the interference
traps must be positioned on the contactor coils. Varistors for over-voltage limitation are also
effective.
6. Shielded or armoured cables should be used for the load connections (motor cable). The shielding
or armouring must be earthed at both ends. The shielding or armouring must be connected over alarge area on the plug connector housing.
Furthermore, attention must be paid to the EMC-compliant wiring.
During the installation of the devices, the safety requirements must not be violated under any
circumstances!

NOTICE!
Damage due to high voltage
The device may be damaged by electrical loads which do not correspond to its specification.
••

Do not perform any high voltage tests on the device itself.
Disconnect the cable which is to be tested from the device before performing a high voltage
insulation test.

If the device is installed according to the recommendations in this manual, it meets all EMC directive
requirements, as per the EMC product standard EN 61800-3.

2.5.5

Electrical connection of power unit

NOTICEEMC interference to the environment
This device produces high-frequency interference, which may make additional suppression measuresnecessary in domestic environments (� 8.1 "Electromagnetic compatibility (EMC)").
The use of shielded motor cables is essential in order to maintain the specified radio interference
suppression level.
When connecting the device, observe the following:••••

The mains supply provides the correct voltage and is suitable for the current required ( 7"Technical data").
Suitable electrical fuses with the specified nominal current range are installed between the voltage
source and the device.
Mains cable connection: on option slot X1 in NORDAC ON motor-mounted, X4 in NORDAC ON+
motor-mounted, NORDAC ON and NORDAC ON+ wall-mounted.
Motor cable connection: on option slot X8
At least one four-core motor cable must be used and U-V-W and PE connected to the plugconnector.

BU 0870 en-4622

31

NORDAC ON + / FC1000 – Manual with installation instructions•

Only copper cables with temperature class 80 °C or equivalent may be used for all connections.

2.5.5.1

Mains connection

No special fuses are required on the mains input side of the device. It is advisable to use mains fuses(see technical data) and a main switch or contactor.
Isolation from or connection to the mains must always be carried out synchronously and for all poles.
In the standard version, the device is configured for operation in TN or TT networks. The mains filter
provides its normal effect and the resulting leakage current. A star point-earthed mains must be used.

WARNING
Unexpected movement in case of mains faults
In case of a mains fault (short circuit to earth) a frequency inverter which is switched off may switch
on automatically. Depending on the parameterisation, this may cause the drive unit to start
automatically and therefore cause a risk of injury.
•

Secure the system against unexpected movement (block, decouple mechanical drive, provide
protection against falling, etc.)

NOTICE
Defect in the device
In case of daisy chain installation, the max. permissible current flowing through the cables is limitedby conductor strips. If the max. permissible current is exceeded, conductor strips in the device may bedamaged.
•Limit the current flowing through the daisy chain cables in such an installation to 12 A.

2.5.5.2

Motor cable

If a shielded motor cable is used or if the cable is installed in a metallic and well-grounded duct, thetotal length should not exceed 5 m (connect cable shield to PE at both ends).
Pre-assembled motor cables are available on request.

NOTICE!
Output switching
Switching a motor cable under load causes an impermissible increase of the load on the device.
Components in the power section may be damaged and destroyed either immediately or in the longterm.
•

Only switch the motor cable when the frequency inverter is no longer pulsing. I.e. the device must
be in the state "ready for switch-on" or "switch-on block".

2.5.5.3

Braking resistor (optionally with size 2 and above)

During dynamic braking (frequency reduction) of a three-phase motor, electrical energy is returned tothe inverter as necessary. With size 2 and above, an internal braking resistor can be used to avoid
shut-down of the device due to overvoltage. With this, the integrated brake chopper (electronic switch)
pulses the link circuit voltage (switching threshold approx. 720 V DC) into the braking resistor. The
braking resistor converts excess energy into heat.

The behaviour of the electromechanical brake is determined by the parameters P280, P281 and P282.
The device checks the brake during operation and generates the following messages in the event of a
fault:
Short circuit at the brake connection

 E004.5 1)

Coil resistance E016.5 2)

Release time E016.6 2)

1)

Message is always taken into account2)

Message is only taken into account after activation via P282.

Irrespective of the supply/mains voltage of the frequency inverter, the brake voltage can be set via theparameter P281 (factory setting: 180 V).

NOTICE
Dielectric strength of the brake
The brake is loaded with pulse voltages of approx. 1000 V by the PWM signal from the brake control.
•

The brake to be controlled must be sufficiently voltage-proof to prevent damage to the brake.

Information

Parameters P280 / P281 / P107 / P114
When connecting an electromechanical brake to the respective terminals of the device, you need toadjust the parameters P280 and P281 (current and voltage mechan. brake) as well as the parameters
P107 and P114 (brake reaction time and delay off). Set value ≠ 0 in parameter P107 to avoid damage
to the brake control.

Information

All control cables (including thermistors) must be routed separately from the mains and the motor
cables to prevent interference in the device.
If the cables are routed in parallel, a minimum distance of 20 cm must be maintained from cables
which carry a voltage of > 60 V. The minimum distance may be reduced by screening the cables
which carry a voltage, or by the use of earthed metal partitions within the cable conduits.

NORDAC ON + / FC1000 – Manual with installation instructions
Encoder input
The incremental encoder connection is an input for a type with two tracks and TTL-compatible signals
for EIA RS 422-compliant drivers. The maximum current consumption of the incremental encoder
must not exceed 150 mA.
The pulse number per rotation can be between 16 and 8192 increments. This is set with the normal
scaling via parameter P301 "Incremental encoder pulse number" in the "Speed control” menu group.
For cable lengths >20 m and motor speeds above 1500 min-1, the encoder should not have more than
2048 pulses/revolution.

Information

Encoder signal faults

Wires that are not required (e.g. Track A inverse/ B inverse) must be insulated. Otherwise, if thesewires come into contact with each other or the cable shield, short-circuits may occur, which can cause
encoder signal problems or destruction of the encoder.

Information

Rotation direction

The counting direction of the incremental encoder must correspond to the direction of rotation of the
motor. If the two directions are not identical, the connections of the encoder tracks (Track A and TrackB) must be switched. Alternatively, the resolution (pulse number) of the encoder in P301 can be set
with a negative prefix.
Alternatively, the motor phase sequence can be changed via parameter P583. In this way the
direction of rotation can be changed using the software only.
Incremental encoder
According to the resolution (pulse number), incremental encoders generate a defined number ofpulses for each rotation of the encoder shaft (Track A / Track A inverse) With this, the precise speedof the encoder or motor can be measured by the frequency inverter. By the use of a second track (B /B inverse) shifted by 90° (¼ period), the direction of rotation can also be determined.
The supply voltage for the encoder is 5 ... 30 V. An external source or the internal voltage can be usedas the voltage source.
TTL encoder
Special terminals are available for connection of a rotary encoder with TTL signals. Parameterisationof the corresponding functions is made with the parameters from the “Speed control” group (P300 etseq.).
HTL encoder
The digital inputs DIN3 and DIN4 are used to connect an encoder with an HTL signal.
Parameterisation of the corresponding functions is performed with parameters P420 [-03/-04].

WARNING
Unexpected movement
Connection of the supply voltage may directly or indirectly set the drive unit into motion. This cancause unexpected movement of the drive and the attached machine, which may result in serious or
fatal injuries and/or material damage. Possible causes of unexpected movements are e.g.:– Parameterisation of an "automatic start"– Incorrect parameterisation– Control of the device with an enabling signal from a higher level control unit (via IO or bus
signals)– Incorrect motor data
– Incorrect encoder connection– Release of a mechanical holding brake– External influences such as gravity or other kinetic energy which acts on the drive unit
– In IT networks: Earth fault (short circuit to earth)•

To avoid any resulting hazard the drive or drive chain must be secured against unexpectedmovements (mechanical blocking and/or decoupling, provision of protection against falling, etc.) In
addition, it must be ensured that there are no persons within the area of action and the danger
area of the system.

4.1

Starting up the device

To establish basic operation capability, after the mechanical installation of the device on a suitablewall or mounted on the motor, the electrical connections must be made ( Section 2.5.5 "Electricalconnection of power unit").
The supply with 24 V DC control voltage is mandatory for commissioning the device.

Information

Factory settings

Before recommissioning it must be ensured that the device is in its factory settings (P523).
Parameters are pre-set (factory settings).
Set the correct motor data and the selection of the operating mode in the parameters. Adaptations to
the drive application, communication settings for other devices or a control unit, as well as optimisationof the operating characteristics are also carried out via parameter settings (see 5 "Parameter").
For the correct operation of the drive unit, it is necessary to enter the motor data (rating plate) as
precisely as possible. In particular, automatic stator resistance measurement using parameter P220 isrecommended.

Motor data for IE3 motors are provided via the NORDCON software. With the aid of the "Import motor

can be selected and imported into the frequency inverter.

4.2

Firmware update

With the integrated bus interface, the frequency inverter offers the option to update both the firmwareof the frequency inverter and the firmware of the integrated bus interface. Details on the different
options can be found in  BU 0820 „Supplementary instructions for SK 300P series“.Selecting theoperating mode for motor control
Motors from NORD are designed as asynchronous motors in efficiency classes IE1 to IE3, and IE4
and IE5 motors are designed as synchronous motors.
The NORDAC ON frequency inverter is able to control asynchronous motors with efficiency classes
IE1 to IE3. The NORDAC ON+ frequency inverter is able to control motors with efficiency class IE5+.
In terms of control technology, IE4 motor operation shows many special features. The frequency
inverter is designed for the control of IE4 and IE5 motors from NORD. In terms of structure, these IE4
motors match the type of an IPMSM (Interior Permanent Magnet Synchronous Motor). In these
motors, the permanent magnets are embedded in the rotor.
The operation of other manufacturer's motors must be checked by NORD, if required. Observe thefollowing additional information:– IE4 synchronous motors: Technical information TI 80-0010 “Planning and Commissioning
Guideline for NORD IE4 Motors with NORD Frequency Inverters”.
– IE5 synchronous motors: Catalogue M5000 “Synchronous motors with IE5+ energy efficiency”.

4.2.1

Explanation of the operating modes (P300)

The frequency inverter provides different operating modes for the control of a motor. All operating
modes can be used with either an ASM (asynchronous motor) or a PMSM (Permanent Magnet
Synchronous Motor), however various constraints must be complied with. In principle, all thesemethods are "flux oriented control methods.
1. VFC open-loop mode (P300, setting "0")This operating mode is based on a voltage-governed flux oriented control method (Voltage Flux
Control Mode (VFC)). This is used for both ASMs as well as PMSMs. In association with theoperation of asynchronous motors this is often referred to as "ISD control".
Control is carried out without the use of encoders and exclusively on the basis of fixed parameters
and the measurement results of actual electrical values. No specific control parameter settings arenecessary for the use of this mode. However, parameterisation of the precise motor data is an
essential prerequisite for efficient operation.
As a special feature for the operation of an ASM there is also the possibility of control according toa simple V/f characteristic curve. This mode of operation is important if several motors which are
not mechanically coupled are to be operated with a single frequency inverter, or if it is only possible
to determine the motor data in a comparatively imprecise manner.
Operation according to a V/f characteristic curve is only suitable for drive applications with relatively
low demands on the quality of speed control and dynamics (ramp times ≥ 1 s). For machines which
tend to have relatively large mechanical vibrations due to their construction, control according to a
V/f characteristic curve can also be advisable. Typically, V/f characteristic curves are used tocontrol fans, certain types of pump drives or agitators. Operation according to a V/f characteristic
curve is activated via parameters (P211) and (P212) (each set to "0").
2. CFC closed-loop – Mode (P300, setting “1”)44

BU 0870 en-4622

4 Commissioning
In comparison with setting “0” “VFC open-loop – Mode”, this is generally a control with currentcontrolled field orientation (Current Flux Control). For this operating mode, which with ASM isfunctionally identical to the designation previously listed under “servo control”, the use of an
encoder is mandatory. This way, the motor’s exact speed characteristics are recorded and includedin the calculation for the motor control. The determination of the rotor position is enabled by theencoder, where for the operation of a PMSM the initial value of the rotor position must be
determined. This allows for a more precise and faster control of the drive.
For ASM and PMSM, this operating mode provides the optimal results in control behaviour, and is
especially suitable for lifting gear applications or applications with requirements on optimal dynamic
behaviour (ramp times ≥ 0.05 s). This operating mode has the greatest benefit in connection with amotor of energy efficiency class IE5+ (energy efficiency, dynamics, precision).
3. CFC open-loop –mode (P300, setting "2")
CFC mode is also possible with the open-loop method, i.e. in operation without an encoder. Here,the speed and position detection are determined by "observation" of measurements and setting
values. Precise setting of the current and speed controller is also essential for this operating mode.
This mode is especially suitable for applications with higher demands for dynamics in comparison
with VFC control (ramp times ≥ 0.25 s) and e.g. also for pump applications with high starting
torques).

Unexpected movement
Connection of the supply voltage may directly or indirectly set the drive unit into motion. This cancause unexpected movement of the drive and the attached machine, which may result in serious or
fatal injuries and/or material damage. Possible causes of unexpected movements are e.g.:– Parameterisation of an "automatic start"– Incorrect parameterisation– Control of the device with an enabling signal from a higher level control unit (via IO or bus
signals)– Incorrect motor data
– Incorrect encoder connection– Release of a mechanical holding brake– External influences such as gravity or other kinetic energy which acts on the drive unit
– In IT networks: Earth fault (short circuit to earth)•

To avoid any resulting hazard the drive or drive chain must be secured against unexpectedmovements (mechanical blocking and/or decoupling, provision of protection against falling, etc.) In
addition, it must be ensured that there are no persons within the area of action and the danger
area of the system.

WARNING
Unexpected movement due to changes in the parameterisation
Parameter changes become effective immediately. Under certain conditions, dangerous situations
may occur, even when the drive is in standstill. Functions such as P428 “Automatic starting” can set
the drive in motion and places persons at risk due to moving parts.
The following applies to parametrisation works:•••

Only change the parameter settings if the Frequency Inverter is not released.
The danger area of the system must not be entered.
Take precautions that prevent accidental movement of the drive (e.g. dropping of lifting
equipment).

WARNING
Unexpected movement due to overload
In case of overload of the drive there is a risk that the motor will "break down" (sudden loss of torque).
An overload may be caused e.g. by inadequate dimensioning of the drive unit or by the occurrence ofsudden peak loads. Sudden peak loads may be of a mechanical origin (e.g. blockage) or may becaused by extremely steep acceleration ramps (P102, P103, P426).
Depending on the type of application, "breakdown" of the motor may cause unexpected movement(e.g. dropping of loads by lifting equipment).
To prevent any risk, the following must be observed:
•
•
•
48

For lifting equipment applications or applications with frequent large load changes, parameter
P219 must remain in the factory setting (100 %).
Do not inadequately dimension the drive unit, provide adequate overload reserves.
If necessary, provide fall protection (e.g. for lifting equipment) or equivalent protective measures.

Information

Factory setting P523

The factory settings of the entire parameter set can be loaded at any time using parameter P523. For
example, this can be useful during commissioning if it is not known which device parameters havebeen previously changed and could have an unexpected influence on the operating behaviour of thedrive.
The restoration of the factory settings (P523) normally affects all parameters. This means that all
motor data must subsequently be checked or reconfigured. However, parameter P523 also provides afacility for excluding the motor data or the parameters relating to bus communication when the factory
settings are restored.
It is advisable to back up the present settings of the frequency inverter beforehand.

Acceleration time

Setting range

0.00 … 320.00 s

Factory setting{ 2.00 }Description

The acceleration time is the time which corresponds to the linear frequency increase
from 0 Hz to the set maximum frequency P105. If an actual setpoint of <100 % isbeing used, the acceleration time is reduced linearly according to the setpoint which
has been set.
The acceleration time can be extended by certain circumstances, e.g. FI overload,
setpoint delay, ramp smoothing, or if the current limit is reached.

Note

Care must be taken that the parameter values are realistic. The setting P102 = 0 is
not permissible for drive units!
Ramp gradient:Amongst other things, the ramp gradient is governed by the inertia of the rotor. A ramp
with a gradient which is too steep may result in “breakdown” of the motor.
Extremely steep ramps (e.g.: 0 – 50 Hz in < 0.1 s) should be avoided, as this may
cause damage to the frequency inverter.

P103

Deceleration time

Setting range

0.00 … 320.00 s

Factory setting{ 2.00 }Description

The deceleration time is the time corresponding to the linear frequency reduction fromthe set maximum frequency P105 to 0 Hz. If an actual setpoint <100 % is being used,the deceleration time reduces accordingly.
The deceleration time can be extended by certain circumstances, e.g. by the selected“Disconnection mode” P108 or “Ramp smoothing” P106.

Note

Care must be taken that the parameter values are realistic. The setting P103 = 0 is
not permissible for the drive units!

Minimum frequency

Setting range

0.0 … 400.0 Hz

Factory setting{ 0.0 }

Description

The minimum frequency is the frequency supplied by the FI as soon as it is enabled
and no additional setpoint is set.
In combination with other setpoints (e.g. fixed frequencies), these are added to the set
minimum frequency.
This frequency is undershot when
• The drive is accelerated from standstill.
• The FI is blocked. The frequency then reduces to the absolute minimum frequency
P505 before it is blocked.
• The FI reverses. Reversal of the rotation field takes place at the absolute minimum
frequency P505.
This frequency can be continuously undershot if the function "Maintain the freq.” (Digit
inputs function = 9) was executed during acceleration or deceleration.

P105

Maximum frequency

Setting range

0.1 … 400.0 Hz

Factory setting{ 50.0 }Description

The frequency supplied by the FI after being enabled and once the maximum setpointis present, (e.g. a correspondingly fixed frequency or maximum via a ParameterBox).
This frequency can only be exceeded by the slip compensation P212, the function“Maintain the freq.” (Digit inputs function = 9) and the switch to another parameter set
with lower maximum frequency.
Maximum frequencies are subject to certain restrictions, e.g.
• Restrictions in weak field operation,• Compliance with mechanically permissible speeds,• PMSM: Restriction of the maximum frequency to a value which is slightly above
the nominal frequency. This value is calculated from the motor data and the input
voltage.

Brake reaction timeP

Setting range

0 … 2.50 s

Factory setting{ 0.00 }Description

Electromagnetic brakes have a physically-dependent delayed Brake reaction time
when actuated. This can result in the dropping of the load in lifting equipment
applications. The brake takes up the load after a delay.
The reaction time must be taken into consideration by setting parameter P107.
Within the adjustable reaction time, the FI supplies the set absolute minimum
frequency P505 and so prevents movement against the brake and load drop when
stopping.
If a time > 0 is set in P107 or P114, at the moment the FI is switched on, the level ofthe excitation current (field current) is checked. If no excitation current is present, theFI remains in excitation mode and the motor brake is not released.

Note

In order to achieve a shutdown and an error message E016 in case of a too low
excitation current, P539 must be set to {2} or {3}.
To control an electromechanical brake, especially for bucket elevators, the connectionof the brake rectifier MB+ and MB- can be used from size 2 and above. The absolute
minimum frequency (P505) should never be less than 2.0 Hz.

S

P

Meaning0

Voltage disable

The output signal is switched off immediately. The FI no longer
supplies an output frequency. The motor is only braked bymechanical friction. Switching the FI on again immediately cancause an error message.

1

Ramp down

The actual output frequency is reduced in proportion to theremaining deceleration time from P103/P105. The DC run-on P559
follows the end of the ramp.

2

Delayed ramping

As with {1 }“Ramp”, however, for generational operation the brakeramp is extended, or for static operation the output frequency is
increased. Under certain conditions, this function can prevent
overvoltage switch-off or reduce braking resistor power dissipation.
Note: This function must not be programmed if defined
deceleration is required, e.g. for lifting equipment.

3

Immediate DC braking

The FI switches immediately to the preselected DC current P109.
This DC current is supplied for the remaining proportion of the “DCbrake time“ P110 Depending on the relationship of the actual
output frequency to the max. frequency P105, the "DC brake time"is shortened. The time taken for the motor to stop depends on theapplication. The time taken to stop depends on the inertia of theload, friction and the DC current which is set in P109.
With this type of braking, no energy is fed back into the FI. Heatlosses primarily occur in the rotor of the motor.
Note: This function is not suitable for PMSM motors

4Const. Braking distance"Constant brake distance": Start of the brake ramp is delayed if
operation is not at the maximum output frequency (P105). This
results in an approximately similar braking distance for different
actual frequencies.
Note: This function cannot be used as a positioning function. Thisfunction should not be combined with ramp smoothing (P106).

5

Combined Braking"Combined braking": Depending on the actual link circuit voltage(UZW), a high frequency voltage is switched to the basic frequency(only for linear characteristic curves P211 = 0 and P212 = 0). The
braking time P103 is complied with if possible.  Additional
heating in the motor!
Note: This function is not suitable for PMSM motors

DC brake current

Setting range

0 … 250 %Factory setting{ 100 }

Description

Current setting for the functions of DC current braking (P108 = 3) and combined
braking (P108 = 5).
The correct setting value depends on the mechanical load and the required
deceleration time. A higher setting brings large loads to a standstill more quickly.
The 100 % setting corresponds to a current value as stored in the "Nominal motor
current" parameter P203.

Note

The DC current (0 Hz) which the FI can supply is limited. For this value, please referto the table in Section 8.2.3 "Reduced overcurrent due to output frequency", column: 0 Hz. In the basic setting this limiting value is 110 %.
DC Braking: Not for PMSM motors!

P110

Time DC-brake on

Setting range

0.00 … 60.00 s

Factory setting{ 2.00 }Description

The time for which the DC current selected in P109 is applied to the motor. For this,function {3} “Instant d.c. Braking”” must be set in P108.
Depending on the relationship of the actual output frequency to the max. frequency

Description"P torque limit factor". Directly affects the behaviour of the drive at the torque limit.
The basic setting of 100 % is sufficient for most drive tasks.
If the values are too high the drive tends to oscillate as it reaches the torque limit. Ifvalues are too low, the programmed torque limit can be exceeded.

Description

With this parameter, a limit value for the torque-generating current can be set. Thiscan prevent mechanical overloading of the drive. However, it cannot provide
protection against mechanical blockages. A slipping clutch which acts as a safety
device is not replaceable.
With the control method “CFC closed-loop” (Servo Mode) P300, setting {1}, a limit

Jog frequency

Setting range-400.0 … 400.0

Factory setting{ 0.0 }

Description

When using the ParameterBox to control the FI, the jog frequency is the starting value
after enabling.
Alternatively, if control is via the control terminals, the jog frequency can be activated
via one of the digital inputs.
Setting of the jog frequency can be performed directly via this parameter or, if the FI isenabled via the keyboard, by pressing the OK key. In this case, the actual output
frequency is applied to parameter P113 and is then available for the next start.

Note

Activation of the jog frequency via one of the digital inputs causes the remote control
to be switched off in case of bus operation. In addition, any set point frequencies
which are present are not taken into account.
Exception: Analogue setpoints which are processed via the functions “Frequency
addition” or “Frequency subtract.”.

P114

Brake delay off

Setting range

0.00 … 2.50 s

Factory setting{ 0.00 }Description

Electromagnetic brakes have a delayed reaction time for their release, which depends
on physical factors. This can lead to the motor running while the brake is still applied,which will cause the inverter to switch off with an overcurrent message.
This release time can be taken into consideration by the parameter P114 (braking
control).
During the adjustable release time P114, the FI supplies the set absolute minimum
frequency P505 and thus prevents movement against the brake.
See also parameter P107 "Brake reaction time" (setting example).

Note

If P114 is set to {0}, then P107 is the brake release and reaction time.

The stator resistance has a direct influence on the current control of the FI. A value
which is too high may result in overcurrent; a value which is too low may result in low
motor torque.
The result of the stator resistance measurement (see P220) is shown in P208.

S

P

The static boost affects the current which generates the magnetic field. This
corresponds to the no-load current of the respective motor and therefore
does not depend on the load. The no-load current is calculated using the
motor data. The factory setting is sufficient for typical applications.

For permanent magnet synchronous motors (PMSM) the level of the current
PMSM which is used for identification can be modified as a percentage. The durationof the dwell process can be set via P558.
P211

Dynamic boost

Setting range

0 ... 150 %Factory setting{ 100 }

Description

Dynamic boost affects the torque-generating current and is therefore a loaddependent parameter. Here too, the factory setting is sufficient for typical applications.
A value which is too high can result in overcurrent in the FI. Under load, the output
current is increased too much. A value which is too low will result in insufficient torque.

Note

In particular, applications with large inertial masses (e.g. fan operation) may require
control according to a V/f characteristic curve. For this, parameters P211 and P212
must each be set to 0%.

P212

Slip compensation

Setting range

0 ... 150 %Factory setting{ 100 }

Description

Slip compensation increases the output frequency depending on the load, in order tokeep the three-phase asynchronous motor speed approximately constant.
The factory setting of 100% is optimal for three-phase asynchronous motors if thecorrect motor data has been set.
If several motors (different loads or outputs) are operated with a single FI, the slip
compensation P212 = 0% must be set. This also applies to synchronous motors which
do not have slip due to their design.

Note

In particular, applications with large inertial masses (e.g. fan operation) may require
control according to a V/f characteristic curve. For this, parameters P211 and P212
must each be set to 0%.

Description

This function allows a value for the expected torque requirement to be set in thecurrent controller. This function can be used in lifting applications for better load takeup during starting.

torques are entered with a negative sign. The reverse applies for the "left" rotation

Description

Only advisable with linear characteristic curve (P211 = 0 % and P212 = 0 %).
For drives which require a high starting torque, this parameter provides an option forswitching in an additional current during the start phase. The application time is limited
and can be selected in parameter "Boost precontrolP216.
All current and torque current limits that may have been set P112, P536, P537 aredeactivated during the boost precontrol.

Note

With active ISD control (P211 and / or P212 ≠ 0 %), parameterisation of P215 ≠ 0
results in incorrect control.

Factory setting{ 0.0 }

Description

This parameter is used for 2 functionalities:
1. Time limit for the boost precontrol: Application time for the increased starting
current.
Only with linear characteristic curve (P211 = 0% and P212 = 0%).
2. Time limit for suppression of pulse disconnection P537: enables start-up underheavy load.

P217

Oscillation damping

Setting range

0... 400 %Factory setting{ 10 }

Description

Parameter is a measure of the damping power. Oscillations caused by resonanceunder no-load conditions can be suppressed with oscillation damping.
For oscillation damping the oscillation component is filtered out of the torque current
by means of a high pass filter. This is amplified by P217, inverted and switched to the
output frequency.
The limit for the value switched is also proportional to P217. The time constant for thehigh pass filter depends on P213. For higher values of P213 the time constant islower.
With a set value of 10% for P217, a maximum of ± 0.045 Hz are switched in. At 400%
in P217, this corresponds to ± 1.8 Hz

in some motors.

Auto. flux adjustment

Setting range

25 ... 100 % / 101

Factory setting{ 100 }

Description"Automatic magn. adjustment". With this parameter, the magnetic flux of the motor
can be automatically matched to the motor load, so that the energy consumption is
reduced to the amount which is actually required. P219 is the limiting value, to which
the field in the motor can be reduced.
Reduction of the field is performed with a time constant of 7.5 s. If the load increases,
the field is increased with a time constant of approx. 300 ms. The field is reduced sothat the magnetisation current and the torque current are approximately equal, i.e. themotor is operated with “optimum efficiency”.
This function is suitable for applications with relatively constant torque (e.g. pump and
fan applications). Its effect therefore replaces a quadratic curve, as it adapts thevoltage to the load.

Note

For applications with rapid torque fluctuations (e.g. lifting equipment) this parametershould be left at the factory setting (100%). Otherwise, rapid load changes could
cause shut-down due to overcurrent or "breakdown".

Description“Reluct. angle IPMSM” In addition to the synchronous torque, synchronous machineswith embedded magnets (IPMSM) also have a reluctance torque. This is due to theanisotropy (imbalance) between the inductance in the d and the q direction. Due to thesuperimposition of these two torque components, the optimum efficiency is not at aload angle of 90° as with SPMSMs, but rather with larger values. This additional
angle, which can be assumed to be 10° for NORD motors, can be taken into accountwith this parameter. The smaller the angle, the smaller the reluctance component.
The specific reluctance angle for the motor can be determined as follows:• Allows drives with constant load ( > 0.5 MN) to run in CFC mode (P300 ≥ 1)
• Gradually increase the reluctance angle P243 until the current P719 reaches aminimum

Description“Ident startrotor pos". Selection of the method for determination of the starting positionof the rotor (initial value of the rotor position) of a PMSM (Permanent Magnet

Setting values

Value

Meaning0

Voltage controlled: With the first start of the motor, a voltage indicator is memorised to ensure thatthe rotor of the motor is set to the rotor position "zero". This type of identifying starting position of therotor can only be used if there is no counter-torque from the motor (e.g. flywheel drive) at frequency"zero". If this condition is fulfilled, this method of identifying the position of the rotor is very accurate(<1° electrical). This method is unsuitable for lifting equipment applications, as there is always acounter-torque.
For operation without encoders: Up to the switch-over frequency P331 the motor (with the nominal
current memorised) is operated under voltage control. Once the switch-over frequency has beenreached, the method for identifying the rotor position is switched over to the EMF method. Ifhysteresis (P332) is taken into into account, the frequency falls below the value in P331, thefrequency inverter switches back from the EMF method to voltage controlled operation.

1

Test signal method: The starting position of the rotor is determined with a test signal. If this method is
also to be used at a standstill with the brake applied, a PMSM with sufficient anisotropy between the
inductance of the d and q axes is required. The greater this anisotropy is, the greater the precision of themethod. With parameter P212 the voltage level of the test signal can be changed and the rotor position
controller can be adjusted with parameter P333. For motors which are suitable for use with the test signal
method, a rotor position accuracy of 5°…10° electrical can be achieved (depending on the motor and theanisotropy). The conditions for activating the test signal method can be selected with P336.

2

Value from universal encoder, “Value from universal encoder”: With this method, the starting
position of the rotor is determined from the absolute position of a universal encoder (Hiperface, EnDatwith Sin/Cos track, BISS with Sin/Cos track or SSI with Sin/Cos track). The universal encoder type is
set in parameter P604. For this position information to be unique, it must be known (or determined)
how this rotor position relates to the absolute position of the universal encoder. This is performed withthe offset parameter P334. Motors should either be delivered with a rotor start position "zero" or therotor starting position must be marked on the motor. If this value is not available, the offset value canalso be determined with the settings {0} and {1} of parameter P330. For this, the drive unit is started
with the setting {0} or {1} After the first start, the determined offset value is stated in the parameter
P334. This value is volatile, i.e. it is only stored in the RAM. In order to save it in the EEEPROM, it
must be briefly changed and then set back to the determined value. After this, fine tuning can be
carried out with the motor running under no load. For this, the drive is operated in closed loop mode
(P300=1) at as high a speed as possible below the field weakening point. From the starting point, theoffset is gradually adjusted so that the value of the voltage component Ud (P723) is as close as
possible to zero. A balance between the positive and negative direction of rotation should be sought.
In general, the value "0" cannot be achieved, as the synchronous motor has a slight load due to the
fan wheel at high speeds. The universal encoder should be located on the motor shaft.
Note: If the UART encoder is used for speed control, rotor position coupling via the setting {2} is notpossible. Fault E19.1 is triggered.

Setting range

Description" Flux feedback CFC open-loop“. This parameter is necessary for the position monitor
in CFC open-loop mode. The higher the value which is selected, the lower the slip
error from the rotor position monitor. However, higher values also limit the lower limit
frequency of the position monitor. The larger the feedback amplification which is
selected, the higher the limit frequency and the higher the values which must be set in
P331 and P332. This conflict of objectives can therefore not be resolved
simultaneously for both optimisation objectives.

Note

The default value is selected so that it typically does not need to be adjusted for
NORD IE5+ motors.

P334

Encoder offset PMSM

Setting range-0,500 ... 0.500 rev

Factory setting{ 0,000 }Description

Evaluation of the zero track is necessary for closed loop operation of PMSM

is then used for synchronisation of the rotor position.
The value to be set for parameter P334 (offset between zero pulse and actual rotor
position "Zero") must be determined experimentally or included with the motor.

Note

NORD motors are delivered so that the zero pulse of the encoder corresponds to thezero pole position of the motor. In case of deviation, this can be obtained from anadhesive label on the motor.

1)

If neither of the digital inputs is programmed for left or right enable, actuation of a fixed frequency or jog
frequency enables the frequency inverter. The rotation field direction depends on the sign of the setpoint

2)

Also effective for control via BUS (e.g. Ethernet, USS)

3)

Function cannot be selected via BusIO In Bits

4)

Notice! When using this function for end position monitoring, it must be ensured that the end position
switch cannot be overrun, because as soon as the end position switch has been left, the blocking of thedirection of rotation is automatically cancelled. The frequency inverter therefore accelerates again whenthe enable signal is applied.

Safety SS1 max. time

Setting range

0.01 ... 320.00 s

Factory setting{ 0.1 }

Description“Safety SS1 max. time” is used to delay the output monitoring of the frequency
inverter if the Safety Digital Input is parameterised to Quick Stop (P424 = 2). If the
motor is still controlled after the set time, an error message is generated. The time tobe set depends on the parameterised quick stop time, the brake reaction time and theflux delay. For asynchronous motors, the time to be set also depends on the DC runon time.

Scope of Application

SK 3x1P with SK CU6-STO

Note

The set “Safety SS1 max. time” applies for all parameter sets. Be sure that the “Quick
stop time” (P426) is matched for all parameter sets of the monitoring time.
The parameter is only saved after entry and confirmation of the “Safety CRC” (P499).
A parameter setting change is only applied after the external 24 V DC supply of thefrequency inverter has been switched off and on again (24 V off  60 s  24 V on).
Switching off the 400 V supply is not required for NORDAC ON or NORDAC ON+.
If the safety functions are used, the parameters must be provided with password
protection by use of “Change safety passw.” (P498).
The “Safety SS1 max. time” (P423) is not changed by “Load factory setting” (P523). If
the “Safety SS1 max. time” (P423) is to be changed to a default value, this must be
carried out manually.

WARNING! Danger of injury due to unexpected movements of the drive. Switch-on
after an earth fault/short-circuit. Do NOT parameterise this parameter to “On”
(P428 = 1), if “Automatic acknowled.” (P506 = 6 “Always”) has been parameterised!
Secure drive against movements.
This parameter defines how the FI responds to a static enabling signal when themains voltage is applied (mains voltage On).
In the standard setting P428 = 0 Off, the FI requires a flank to enable (signal change
from Low  High) at the relevant digital input.
P428 = 1 “On” can be set if the FI must start immediately when the mains voltage isswitched on. If the enable signal is permanently switched on, or equipped with a cablejumper, the FI starts up immediately.

Note

The setting “On” (P428 = 1) can only be enabled if the frequency inverter has been
parameterised to local control (P509 = 0 or P509 = 1).

Fixed frequency 1

Setting range-400.0 … 400.0 Hz

Factory setting{ 0.0 }

Description

Following actuation via a digital input and enabling of the device (right or left), thefixed frequency is used as a setpoint. A negative setting value will cause a phasesequence reversal (based on the Enable rotation direction P420).
If several fixed frequencies are actuated simultaneously, the individual values areadded with the correct sign. This also applies to combinations with the jog frequency
P113 or minimum frequency P104.
If none of the digital inputs are programmed for enable (right or left), the simple fixed
frequency signal results in an enable. A positive fixed frequency corresponds to a rightenable, a negative to a left enable.

The frequency limits P104 = fmin or P105 = fmax cannot be overshot or undershot.

Inverter name

Setting range

A … Z (char)

Arrays[-01] … [-20]

Factory setting{0}

Description

Free input of a designation (name) for the device (max. 20 characters). With this, thefrequency inverter can be uniquely identified for setting with NORDCON software orwithin a network.

P504

Pulse frequency

Setting range

16.4 kHz

Factory setting{ 6.0 }

Description

The internal pulse frequency for controlling the power unit can be changed with thisparameter. A higher setting value reduces motor noise, but leads to increased EMC
emissions and reduction of the possible motor torque.

Note

The best possible degree of interference suppression for the device is achieved byusing the default value and taking the wiring directives into consideration.

S

Raising the pulse frequency leads to a reduction of the possible output current,
depending on the time (I2t curve). When the temperature warning limit C001 isreached, the pulse frequency is gradually lowered to the default value (see also
P537). If the inverter temperature drops by a sufficient amount, the pulse frequency is
increased to the original value.
The pulse frequency must not change if a sine filter is used. Otherwise, “Module
errors” (E4.0) can be triggered.
See setting {16.2 } and {16.3}.
Setting values

Value

Meaning

min.
…
16.0

Pulse frequency min.… 16.0 kHz

The value which is set is used as the standard pulse frequency.
With increasing overload the frequency inverter automatically
gradually reduces the pulse frequency to the default value.

16.1

Automatic setting of the maximum
possible pulse frequency

The frequency inverter continuously determines and automaticallysets the highest possible pulse frequency.

16.2

Pulse frequency 6 kHz

16.3

Pulse frequency 8 kHz

Fixed pulse frequency setting. This value remains constant even incase of overload (suitable for operation with a sine filter).
NB: With these settings, short circuits at the output which occur
before enabling may possibly not be detected correctly.

16.4

Automatic load adjustment

The pulse frequency is automatically adjusted between a minimum
value (highest load reserve) and a maximum value (lowest load
reserve) depending on the load.
During an acceleration phase and if high power is required (≥ rated
power) the minimum value is set. With constant speed and a power
requirement ≤ 80 % rated power, the high pulse frequency is set.

P505

Absolute mini. freq.

Setting range

0.0 … 10.0 Hz

Factory setting{2}

Description“Absolute minimum frequency”. Specifies the frequency value that cannot be
undershot by the FI. If the setpoint becomes smaller than the absolute minimum
frequency, the FI switches off or changes to 0.0 Hz.
At the absolute minimum frequency, braking control P434 and the setpoint delay P107
are executed. If the setting value “Zero” is selected, the brake relay or the digital
output, which is assigned the function { 1 } in P434, does not switch during reversing.
When controlling lift equipment without speed feedback, this value should be set to aminimum of 2 Hz. With 2 Hz and above, the current control of the FI operates and aconnected motor can supply sufficient torque.

Note

Output frequencies < 4.5 Hz result in current limitation .

PMSM: The catch function automatically determines the direction of rotation.
Therefore, if function 2 is set, the device behaves identically to function 1. If function 4
is set, the device behaves identically to function 3.
PMSM: In CFC closed loop mode, flying start can only be executed if the rotor position
is known in relation to the incremental encoder. For this purpose, the motor cannot
initially rotate when it is switched on for the first time after a "mains on" of the FI.
This restriction does not apply if the zero track of the incremental encoder is used.

Description

This function prevents rapid shutdown of the FI according to the load. With the pulse
switch-off enabled, the output current is limited to the set value. This limitation is
implemented by briefly switching off individual output stage transistors; the actual
output frequency remains unchanged.

Note

The value set here can be undershot by a smaller value in P536.
For smaller output frequencies (< 4.5 Hz) or higher pulse frequencies (> 6 kHz or
8 kHz, P504), pulse switch-off by power reduction can be undershot.
If the function is disabled and a high pulse frequency is selected in parameter P504,
the frequency inverter automatically reduces the pulse frequency when the power
limits are reached. If the load on the inverter is reduced, the pulse frequency
increases back to the original value.

Description"Minimum chopper threshold". Adjustment of the switching threshold of the brake
chopper.

Note

An increase in this setting leads to a faster overvoltage FI switch off.
For applications where pulsating energy is returned (crank drives) the braking resistor
power dissipation can be minimised by increasing this setting.
In case of an FI error the brake chopper is generally disabled.

Setting range

Description"Chopper power limit“. With this parameter it is possible to program a manual (peak)
power limit for the braking resistor. The switch-on delay (modulation level) for the
chopper can only rise to a certain maximum specified limit. Once this value has beenreached, irrespective of the level of the link circuit voltage, the inverter switches off thecurrent to the resistor.
The result would be an overvoltage switch-off of the FI.

The ISD control can only function correctly if there is a magnetic field in the
motor. For this reason, a DC current is applied before starting the motor toprovide excitation of the stator winding. The duration depends on the size ofthe motor and is automatically set in the factory setting of the FI. For timecritical applications the flux delay can be set or disabled.

When used with PMSM, the dwell time can be set via this parameter during
PMSM rotor position identification using the dwell method. Total dwell duration = 2.5

After a stop signal and elapse of the brake ramp, direct current is applied to the motor
for a short time. This should completely stop the drive. Depending on the inertia, thetime for which the current is applied can be set in this parameter.
The current level depends on the previous braking procedure (current vector control)or the static boost (linear characteristic).

6 Operating status messages
In case of deviations from the normal operating status, a message is output. There are:•••Error messages: Faults cause the device to switch off.
Warning messages: A limit value has been reached. The device will continue to run. If the cause
for the warning persists, the device enters the fault state.
Inhibit notification (switch-on block): External influences prevent starting.

The messages are stored in the information parameter (P700).

6.1

Display of messages

LED indicators
The device status is indicated by an externally visible “device status” LED ( 3.2 "Diagnostic LED").
SimpleBox Display
The SimpleBox displays an error with its number and the prefix "E". In addition, the present fault canbe displayed in array element [-01] of parameter (P700). The last error messages are stored inparameter (P701). Further information about the frequency inverter status at the moment of the fault
can be obtained from parameters (P702) to (P706) / (P799)
If the cause of the error is no longer present, the error display in the SimpleBox flashes and the error
can be acknowledged with the Enter key.
In contrast, warning messages are prefixed with "C" ("Cxxx") and cannot be acknowledged. They
disappear automatically when the reason for them is no longer present or the frequency inverter has
switched to the "Error" state. Display of the message is suppressed if the warning appears during
parameterisation.
The present warning message can be displayed in detail at any time in array element [-02] ofparameter (P700).
The reason for an existing disabled switch on cannot be displayed with the SimpleBox.
ParameterBox display
The ParameterBox displays the messages in plain text.

Electromagnetic compatibility (EMC)

8.1.1

General Provisions

As of July 2007, all electrical equipment which has an intrinsic, independent function and which is soldas an individual unit for end users, must comply with Directive 2004/108/EEC (formerly Directive
EEC/89/336). There are three different ways for manufacturers to indicate compliance with thisdirective:
1. EU Declaration of Conformity
This is a declaration from the manufacturer, stating that the requirements in the applicable
European standards for the electrical environment of the equipment have been met. Only thosestandards which are published in the Official Journal of the European Community may be cited in
the manufacturer’s declaration.
2. Technical documentation
Technical documentation can be produced which describes the EMC characteristics of the device.
This documentation must be authorised by one of the “Responsible bodies” named by the
responsible European government. This makes it possible to use standards which are still in
preparation.
3. EU Type test certificate
This method only applies to radio transmitter equipment.
The devices only have an intrinsic function when they are connected to other equipment (e.g. to a
motor). The base units cannot therefore carry the CE mark that would confirm compliance with the
EMC directive. Precise details are therefore given below about the EMC behaviour of this product,
based on the proviso that it is installed according to the guidelines and instructions described in thisdocumentation.
The manufacturer can certify that his equipment meets the requirements of the EMC directive in therelevant environment with regard to their EMC behaviour in power drives. The relevant limit values
correspond to the basic standards EN 61000-6-2 and EN 61000-6-4 for interference immunity andinterference emissions.

BU 0870 en-4622

8.1.2

EMC evaluation

Two standards must be observed when evaluating electromagnetic compatibility.
1. EN 55011 (environmental standard)
In this standard, the limit values are defined in dependence on the basic environment in which the
product is operated. A distinction is made between two environments, where the first environment
describes the non-industrial living and business area without its own high-voltage or mediumvoltage distribution transformers. The second environment defines industrial areas, which are
not connected to the public low-voltage network, but have their own high-voltage or mediumvoltage distribution transformers. The limit values are subdivided into classes A1, A2 and B.
2. EN 61800-3 (product standard)
In this standard, the limit values are defined in dependence on the usage area of the product. The
limit values are subdivided into categories C1, C2, C3 and C4, where class C4 basically only
applies to drive systems with higher voltage (≥ 1000 V AC) or higher current (≥ 400 A). However,class C4 can also apply to the individual device if it is incorporated in complex systems.
The same limit values apply to both standards. However, the standards differ with regard to an
application that is extended in the product standard. The operator decides which of the two standards
applies, whereby the environmental standard typically applies in the event of a fault remedy.
The main connection between the two standards is explained as follows:

EMC of device

NOTICEEMC interference to the environment
This device produces high-frequency interference, which may make additional suppression measuresnecessary in domestic environments (� 8.1 "Electromagnetic compatibility (EMC)").
The use of shielded motor cables is essential in order to maintain the specified radio interference
suppression level.
The device is exclusively intended for commercial use. It is therefore not subject to the requirementsof the standard EN 61000-3-2 for radiation of harmonics.
The limit value classes are only achieved if••

the wiring is EMC-compliant
the length of shielded motor cable does not exceed the permissible limits•

The standard pulse frequency (P504) is used

The motor cable shield must be connected on both sides.

Reduced output power

The frequency inverters are designed for special overload situations. For example, 1.5x overcurrent
can be used for 60 s. For approx. 3.5 s, 2x overcurrent is possible. A reduction of the overload
capacity or its duration must be considered for the following circumstances:••••

Output frequencies < 4.5 Hz and DC voltage (stationary pointer)
Pulse frequencies greater than the nominal pulse frequency (P504)
Increased mains voltages > 400 V
Increased heat sink temperature

The following characteristic curves can be used to obtain the corresponding current/power limit.

8.2.1

Derating depending on the pulse frequency

This illustration shows how the output current must be reduced, depending on the pulse frequency inorder to avoid excessive heat dissipation in the frequency inverter. Reductions starts at 6 kHz.
With the applicable rated current of Figure 2, a differentiation must be made between wall-mounted
and motor-mounted inverters. In case of wall-mounting, the graph below applies and the inverter rated
current may be taken as IN.
For a motor-mounted frequency inverter, the internal temperature of 90 °C is decisive and must not be
exceeded. The graph in Figure 2 only serves as a reference point where IN corresponds to the rated
motor current.
The diagram shows the possible current load capacity for continuous operation.

Reduced overcurrent due to the time

Depending on the duration of an overload, the possible overload capacity changes. Some values arehighlighted in these tables. If one of these limit values is reached, the frequency inverter must havesufficient time (at low load or without load) to regenerate.
If operation is repeatedly carried out in the overload range at short intervals, the limit values stated in
the tables are reduced.

Reduced overcurrent due to output frequency

To protect the power unit at low output frequencies (< 4.5 Hz), monitoring is provided to determine thetemperature of the IGBTs (insulated-gate bipolar transistor) due to high current. A pulse disconnection(P537) with variable limit is introduced so that no current can be accepted above the limit shown in the
diagram. At standstill with 6 kHz pulse frequency, no current can thus be accepted above 1.1x thenominal current.

The resulting upper limit values for the pulse disconnection for the various pulse frequencies can befound in the following tables. The adjustable value (0.1 ... 1.9) that can be set in parameter P537 is inany case limited to the value specified in the tables depending on the pulse frequency. Values below
the limit can be adjusted as required.

Reduced output current due to low voltage

The frequency inverters are thermally designed with regard to the rated output currents. For lower low
voltages larger currents cannot be used in order to keep the output power constant. For mains
voltages above 400 V the permissible output current is reduced inversely proportional to the mains
voltage in order to compensate for switching losses.
I / IN

Mains voltage [V]Figure 3: Reduced output current due to low voltage

8.2.5

Reduced output current due to the heat sink temperature

The temperature of the heat sink in included in the calculation of the reduction of output current, sothat at low heat sink temperatures, a higher load capacity can be permitted, especially for higher pulse
frequencies. At high heat sink temperatures, the reduction is increased correspondingly. The ambient
temperature and the ventilation conditions for the device can therefore be optimally exploited.

8.3

Operation on the FI circuit breakerFor devices with an active mains filter (standard configuration for TN- / TT networks) leakage currentsof ≤ 16 mA are to be expected. These are designed for operation with leakage current circuit breakers
for the protection of persons.
For devices with an inactive mains filter (special configuration for TN networks) leakage currentsof ≤ 30 mA are to be expected. These are not suitable for operation with leakage current circuit
breakers for the protection of persons.
Only all-current sensitive FI circuit breakers (type B or B+) must be used.

In case of overload of the drive there is a risk that the motor will "break down" (sudden loss of torque).
An overload may be caused e.g. by inadequate dimensioning of the drive unit or by the occurrence ofsudden peak loads. Sudden peak loads may be of a mechanical origin (e.g. blockage) or may becaused by extremely steep acceleration ramps (P102, P103, P426).
Depending on the type of application, "breakdown" of the motor may cause unexpected movement(e.g. dropping of loads by lifting equipment).
To prevent any risk, the following must be observed:•••

For lifting equipment applications or applications with frequent large load changes, parameter
P219 must remain in the factory setting (100 %).
Do not inadequately dimension the drive unit, provide adequate overload reserves.
If necessary, provide fall protection (e.g. for lifting equipment) or equivalent protective measures.

NORD frequency inverters have a low power consumption and are therefore highly efficient. In
addition, with the aid of "Automatic flux optimisation" (Parameter (P219)) the inverter provides a
possibility for increasing the overall efficiency of the drive in certain applications (in particularapplications with partial load).
According to the torque required, the magnetisation current through the frequency inverter or the
motor torque is reduced to the level which is required for the momentary drive power. The resulting
considerable reduction in power consumption, as well as the optimisation of the cos φ factor of the
motor rating in the partial load range contributes to creating optimum conditions both with regard toenergy consumption and mains characteristics.
A parameterisation which is different from the factory setting (Factory setting = 100%) is only
permissible for applications which do not require rapid torque changes. (For details, see Parameter(P219))
