Preventative Maintenance Advance Notification

InverterdiagnosticNEWfunctions

Actual operation data can be monitored to predict the degree of power modules cycle degradation (approximate). In addition
to the lifetime assessment of capacitors and cooling fans of our WJ200, a lifetime assessment of power modules is installedin the new WJ series C1(Afterward “WJ Series C1” referred as WJ-C1.) Preventative maintenance is realized by lifetime
assessment of components. This function can prevent system downtime in production line, or essential operations.

Parameters can be set prior to installation
by 24VDC control power supply.
In addition to the normal power supply, WJ-C1 can be operated by supplying an external 24VDC. Parameter setting can be done before going on site because WJ-C1 can be operated without the main power
supply. Therefore, installation time on site can be shortened and operational efficiency increased. You
can also connect to a PLC to program or operate using the PC Setting Software (ProDriveNext).

of WJ-C1.

functions

Simple vector control without the need for optional board

versionUP

WJ-C1 can use simple vector control without an additional optional board.

It supports IM motor sensorless vector control and V/f control. The WJ-C1 can calculate and compensate the speed deviation frominternally calculated speed sensor data in real time while improving torque characteristics.
Example: V/f control

Commands to the motor.

When the inverter outputs
frequency and voltage
commands to the motor, if aload of the motor is large, thespeed will be delayed.

Example: Simple vector control
Commands to the motor.
Check the operation statusof the motor.
The command is output
again so that the target
speed is reached.

The inverter checks theoperation status of the motorin simple vector control. The
command is output again sothat the target speed isreached, and no delay is
generated.

Reduction of system hardware cost by multiple PID function

versionUP

WJ-C1 has two PID loop controllers. The inverter controls the operation of the motor with PID controller,
and an external device can also be controlled independently with another PID controller.
Therefore, WJ-C1 can control the motor and the external device without a host device, such as a PLC.

Example: Inverter control of pump flow rate
+ temperature control of heater

PID1

Waveform can be checked by trace function
without measuring instruments

This function visualizes the sampling data ofparameters selected by an operator.
The operator can then check the status of WJ-C1
by checking waveform at "trip" without additionalor external measuring instruments.

NEWfunctions

Pay attention to thespecification difference fromthe assumed measuring
instrument.
※PC software (ProDriveNext) for inverter-setting is required to check the data.
Please contact the supplier where this device was purchased or local Hitachi
inverter sales office to get PC software(ProDriveNext).

Energy saving by PM motor

WJ-C1 is equipped with both control functions for induction motor and PM motor. The controller canbe re-parametrized when replacing an induction motor with a PM motor. In addition, the new overcurrent-level setting function prevents a demagnetizing of PM motor due to overcurrent.
PM motors that contribute to energy
conservation

Overcurrent level adjustment
The overcurrent trip level can be adjusted by parameters.

PM motors are more efficient than induction motors,
contributing to energy savings. Energy measures will
help to reduce costs, while at the same time resolving
global environmental issues.

Description
Common terminal for internal power supply, input terminal [1] to [8], analog input/
output and pulse output terminals.
This is a 10 VDC power supply. It is used
when using analog input terminals and variable resistor for inputting voltage.
Analog voltage/current input terminals.
Analog voltage/current input can be selected for each terminal by parameter setting.
- Analog voltage input
0 to 10 VDC voltage input. It is adjusted at the factory to reach the maximum
frequency at 9.8 VDC input.
- Analog current input
4 to 20 mA current inputs. It is adjusted at the factory to reach the maximum
frequency at 19.8 mA input.
When "Thermistor type selection [Cb-40]" set to "PTC (01)", [5] terminal is forexternal thermistor input.
An external thermistor is connected between this terminal and the [L] terminal to trip
the inverter due to a temperature error.
Regardless of the sink or source logic, the common is the [L] terminal.
Common terminal for internal power supply, input terminal [1] to [8], analog input/
output and pulse output terminals.
24 VDC internal power supply terminal for contact input. Common for source logic input.
By supplying external 24 VDC to this terminal, it is possible to operate only the control
board and parameters can be read/written. When an external power supply isconnected, be sure to connect a reverse current prevention diode.
Sink logic: short-circuit to [P24] terminal
Source logic: short-circuit to [L] terminal
When driving the contact input with an external power supply, remove the shortcircuit wire. See P18 Connecting the intelligent input terminals to a programmablecontroller" for more information.

Cause(s)Motor overload error *1

Shuts off the inverter output and trips, when detecting a large output current exceeding the overcurrent level. Overcurrent level can be set by Overcurrent
detection level [bb160]. In factory setting, [bb160] is set to 2.2 times the rated output current at ND rating regardless of ND/LD rating setting. When a large output
current exceeding the overcurrent level is detected, the inverter can perform to retry for a certain number of times without tripping by the parameter setting.
Shuts off the inverter output and trips when the electronic thermal function detects a motor overload monitoring the inverter output current. Time until motor
overload error and the behavior after motor overload error is changed according to the setting of the motor rated current and the electronic thermal function.

Braking resistor overload
error

Shuts off the inverter output and trips, when the braking resistor operation circuit (BRD) usage rate exceeds the usage rate specified in Dynamic
brake use ratio [bA-60].

Over current error

Overvoltage error
Memory error
Undervoltage error

Shuts off the inverter output and trips, when detecting a high DC bus voltage exceeding the overvoltage level. Overvoltage level is approx. 400 VDC (200 V
class) or approx. 800 VDC (400 V class). When a high DC bus voltage exceeding the overvoltage level is detected, the inverter can perform to retry for acertain number of times without tripping by the parameter setting.
Shuts off the inverter output and trips, when the internal memory has problems. CPU error [E011] may be issued instead. The reset operation is
not accepted. A power on reset is required. When the inverter recovers by a power on reset, make sure the parameter setting is correct.
Shuts off the inverter output and trips, when detecting a low DC bus voltage below the undervoltage level to prevent the temperamental circuit
operation Undervoltage level is approx. 173 VDC (200 V class) or approx. 345 VDC (400 V class). When a low DC bus voltage below theundervoltage level is detected, the inverter can perform to retry for a certain number of times without tripping by the parameter setting.

E012

Input overvoltage error

Shuts off the inverter output and trips, when the inverter power is turned on while applied an RUN command. Unattended start protection
function is valid when input terminal function Unattended start protection [USP] is turned on or [USP] active selection [CA-73] is Enable (01).
RUN command detection is executed for 2 second after the power is turned on.
The inverter instantly protects from ground-fault, when detects the ground fault between the inverter output and the motor on power up. The function does not work while
inverter trips. Enable/disable of the ground fault detection can be selected by Detect ground fault selection[bb-64] setting. When the external 24 VDC power supply has
been turned on prior to the main power supply(R, S, T), the ground fault detection function is activated at the time the main power supply is turned on.
When Power supply overvoltage selection [bb-61] is Error (01), the inverter trips when persist overvoltage condition for more than 100 seconds while theinverter is in stop status. Input overvoltage level can be set by Power supply overvoltage level setting [bb-62].

E019

Temperature error

Shuts off the inverter output and trips, when the internal temperature is above the threshold.

E021

CPU communication error

Shuts off the inverter output and trips, when occurs a communication error in an internal CPU.

E022

Input phase loss

Shuts off the inverter output and trips, when detects a phase loss of input side of main circuitry. Enable/disable of the input phase loss detection can be selected by Input
phase loss detection enable [bb-65] setting. The single-phase inverters shut off the power when input phase loss. In this case, set [bb-65] to Disable (00).

E024

Shuts off the inverter output and trips, when occurs a malfunction on the main circuit board.

E025

When [Ai1] input selection [Cb-08] or [Ai2] input selection [Cb-18] is Current (02), the inverter trips when excessive current come into the analog
input terminal [Ai1]/[Ai2]. Power off the inverter when occurs this error, and check the wiring connection of analog input.

E026

Driver error

At the time of an instantaneous overcurrent from motor or external braking resistor, or the main element failure the inverter turns off the output toprotect the main element.
Shuts off the inverter output and trips, when a loose connection, disconnection of output line, disconnection inside the motor, etc., are detected.
Enable/disable of the output phase loss detection can be selected by Output phase loss detection enable [bb-66] setting.Detection of output phaseloss is executed in the section of output frequency 5Hz to 100Hz.
Shuts off the inverter output and trips, when an abnormal temperature is observed with an external thermistor. When Thermistor type selection [Cb-40] is PTC (01),the input terminal [5] become for external PTC type thermistor. In this case, Input terminal [5] function [CA-05] setting is invalid. The threshold of abnormal
temperature can be set by Thermistor error level [bb-70] and Thermistor gain adjustment [Cb-41]. When [Cb-40] is PTC (01), this error is occurred when the external
thermistor is disconnected and re-generated after trip reset. In this case, it is required to connect the thermistor or short between [5] terminal and [L] terminal.
Shuts off the inverter output and trips, when the inverter can not detect whether the input function Answer back from brake [BOK] is ON or OFF
during Brake release wait time ([AF131], [AF134]) after the inverter has output a Brake release [BRK]. When [BOK] is not assigned to Input
terminal function([CA-01] to [CA-08]), this error is not occurred.

E030

Overload error at low
speed

When the inverter operate lower than 0.2 Hz, shuts off the inverter output and trips when the electronic thermal function detects a motor overload
monitoring the inverter output current to prevent the main element failure.

E038

Controller overload error

Shuts off the inverter output and trips when the thermal electronic function detects an inverter(controller) overload monitoring the inverter output current. When the controller
overload error occurs, reset command can not be accepted for 10 seconds. There is no user parameter for controller (inverter) overload protection. the controller overload
detection is according to the rated output current at ND rating. It is impossible to change the time until controller overload error and the behavior after controller overload

*1 When Electronic thermal decrease function enable [bC112] is Disable (00), the inverter does not accept a reset operation for 10 seconds. Wait for a while before performing a reset operation.
When [bC112] is Enable (Linear decrement) (01) or Enable (Time constant decrement) (02), it can be reset immediately after error occurs. However, the overload accumulated value is notcleared and the value continue to decrease after reset operation.Therefore, when the inverter is restarted immediately after reset operation, the overload accumulated value may quickly reach
100% and the error may occur again. In this case, wait for a while before restarting.

Inverter• Cautions when using multiple inverters
If a common input (switch, etc.) is used
for multiple inverters and the timing of
power-on is different, the current may
run around as shown in the figure on
the right, and it may be recognized as
ON even if the input is OFF. In thatcase, be sure to insert a diode (rated
50 V/0.1 A) in the positions shown in
the figure to prevent the current flowround. For the source logic, refer to the
User's Guide.

VW• If the wiring length exceeds 20 m, a thick power line needs to be used.
• Use 0.75 mm2 wire for relay output terminals.
• Tighten the terminal screws at specified torques. Loose tightening may cause a short circuit or fire. Excessive
出力側 tightening may damage the terminal block or inverter.

between the inverter and the motor. Also, use an inverter-compatible type earth-leakage breaker. High-speed type products may malfunction.
• Leakage current is approx. 30 mA/km when XLPE wire is used and wired with a metal tube.
• As relative permittivity of HIV wire is high, the leakage current of HIV wire increases by about 8 times that of XLPE
❾ wire.
• Therefore, use an item with 8 times sensitivity current that is shown on the table right. If the total wiring length exceeds 100 m, use a XLPE wire.
• To comply with the UL standard, Class J time-delay fuses or semiconductor fuses of UL standard should be connected on the power supply side.

Function
Refer to table of the recommended wire diameter and wiring tools.
This is applied as a countermeasure against harmonicモータ
suppression, or when imbalance of power supply
IM capacity is 500 kVA or above. It is also used when a rapid
voltage is 3% or above, or when power supply
change is made to power supply voltage. It is also effective in improving power factor.
This reduces conducted noise generated from the inverter and transmitted through the wires.
Connected to the primary side (input side) of the inverter.
When the inverter is used, noise may be generated on an adjacent radio or other devices through wiring on
the primary side (input side) of inverter. This is used for reducing the noise (reducing radiation noise).
This reduces the radiation noise that is emitted from the wire on the input side.
This suppresses harmonics generated from the inverter.
This is used for increasing the braking torque of inverter, repeating power on and off at high interval,
or reducing the speed of high load caused by moment of inertia.
This is installed between the inverter and motor to reduce the radiation noise that is emitted fromthe wire. It is used to reduce radio interference on radios or televisions or prevent malfunctioning of
measurement instruments and sensors.
This is applied for reducing noise generated on the output side of inverter. (It can be used on both
input side and output side.)
When a general-use motor is driven by the inverter, compared with when it is run by commercial power supply,
larger vibration may be generated. By connecting this device between the inverter and motor, the vibration of
motor can be reduced. Also, if the wiring length between the inverter and motor is long (10 m or longer), byinserting a reactor, malfunctioning of the thermal relay caused by harmonic attributable to switching of inverter
can be prevented. It is also possible to use a current sensor instead of a thermal relay.
This is an output-side sinusoidal filter to be installed between the inverter and motor to improve
output current and voltage waveform to reduce motor vibration, noise, and radiation noise from wires.
It is also effective in suppressing surge voltage.

For Correct Operation
Application to Motors

Application to general-purpose motors
Operating frequency

For operation at higher than 60Hz, it is required to examine the allowable torque of the motor, useful life of bearings, noise, vibration,etc. In this case,be sure to consult the motor manufacturer as the maximum allowable rpm differs depending on the motor capacity, etc.

Torque characteristics

The torque characteristics of driving a general-purpose motor with an inverter differ from those of driving it using commercial power(starting torque decreases in particular). Carefully check the load torque characteristic of a connected machine and the driving torquecharacteristic of the motor.

Motor loss andtemperature increase

An inverter-driven general-purpose motor heats up quickly at lower speeds. Consequently, the continuous torque level (output) will
decrease at lower motor speeds. Carefully check the torque characteristics vs speed range requirements.

Noise

A general-purpose motor audible noise run by an inverter is slightly greater than it by a commercial power.

Vibration

When run by an inverter at variable speeds, the motor may generate vibration, especially because of (a) unbalance of the rotor
including a connected machine, or (b) resonance caused by the natural vibration frequency of a mechanical system. Particularly, be
careful of (b) when operating at variable speeds a machine previously fitted with a constant speed motor. Vibration can be minimizedby (1) avoiding resonance points using the frequency jump function of the inverter, (2) using a tireshaped coupling, or (3) placing arubber shock absorber beneath the motor base.

Power transmission
mechanism

Under continued, low-speed operation, oil lubrication can deteriorate in a power transmission mechanism with an oil-type gear box(gear motor) or reducer. Check with the motor manufacturer for the permissible range of continuous speed. To operate at more than
60 Hz, confirm the machine's ability to withstand the centrifugal force generated.

Application to special motors
Gear motor

The allowable rotation range of continuous drive varies depending on the lubrication method or motor manufacturer.
(Particularly in case of oil lubrication, pay attention to the low frequency range.)

Brake-equipped motor

For use of a brake-equipped motor, be sure to connect the braking power supply from the primary side of the inverter.

Pole-change motor

There are different kinds of pole-change motors (constant output characteristic type, constant torque characteristic type, etc.), withdifferent rated current values. In motor selection, check the maximum allowable current for each motor of a different pole count. At
the time of pole changing, be sure to stop the motor. Also see: Application to the 400V-class motor.

Submersible motor

The rated current of a submersible motor is significantly larger than that of the general-purpose motor. In inverter selection, be sure
to check the rated current of the motor.

Explosion-proof motor

Inverter drive is not suitable for a safety-enhanced explosion-proof type motor. The inverter should be used in combination with apressure-proof explosion-proof type of motor.

Synchronous (MS) motor
High-speed (HFM) motor

In most cases, the synchronous (MS) motor and the high-speed (HFM) motor are designed and manufactured to meet the
specifications suitable for a connected machine. As to proper inverter selection, consult the manufacturer.

Single-phase motor

A single-phase motor is not suitable for variable-speed operation by an inverter drive. Therefore, use a three-phase motor.

Permanent magnet motor

Voltage is induced at the motor power terminal during motor rotation even if the inverter power supply is cut off.
Therefore, please do not touch the terminals of the motor and inverter during motor rotation. PM motor can not be operated withcommercial power supply. In addition, PM motor and inverter are ""one to one"" combination. Contact your dealer when you use PM motor.

Application to the 400V-class motor
A system applying a voltage-type PWM inverter with IGBT may have surge voltage at the motor terminals resulting from the cable constants including
the cable length and the cable laying method. Depending on the surge current magnification, the motor coil insulation may be degraded. In particular,when a 400V-class motor is used, a longer cable is used, and critical loss can occur, take any of the following countermeasures:(1) install the LCR filter between the inverter and the motor,(2) install the AC reactor between the inverter and the motor, or (3) enhance the insulation of the motor coil.

Notes on Use
Drive

Run/Stop

Run or stop of the inverter must be done with the keys on the operator or through the control circuit terminal. Do not operate byinstalling a electromagnetic contactor (MC) in the main circuit.

Emergency motor stop

When the protective function is operating or the power supply stops, the motor enters the free run stop state. When an emergency
stop is required or when the motor should be kept stopped, use of a mechanical brake should be considered.

High-frequency run

A max. 590Hz can be selected on the WJ series C1. However, a two-pole motor can attain up to approx. 35,400 min-1, which isextremely dangerous. Therefore, carefully make selection and settings by checking the mechanical strength of the motor andconnected machines. Consult the motor manufacturer when it is necessary to drive a standard (general-purpose) motor above 60 Hz.
High frequency motors are also available in Hitachi.

Repetitive operation on starting or plugging

About frequent repetition use (crane, elevator, press, washing machine) , a power semiconductor (IGBT, a rectification diode, thyristor) in the inverter may
come to remarkably have a short life by thermal fatigue.
The life can be prolonged by lower a load electric current, lengthen acceleration / deceleration time, lower carrier frequency, or increasing capacity of the inverter.

Operation use in highlands beyond 1,000m above sea level
Due to the air density decreasing, whenever standard inverters are used for altitudes above 1000m, the following conditions are additionally required forproper operation. In application for operation over 2500m, kindly contact your nearest sales office for assistance.
1. Reduction of inverter rated current
Current rating has to be reduced 1% for every 100m that exceeds from an altitude of 1000m.
For example, for inverters placed at an altitude of 2000m, the rated current has to be reduced 10% (Rated current x0.9) from its original amount.
{(2000m-1000m)/100mx-1%=-10%}
2. Reduction of breakdown voltage
Whenever an inverter is used at altitudes beyond 1000m, the breakdown voltage decreases as follows:
1000m or less: 1.00 / 1500m: 0.95 / 2000m: 0.90 / 2500m: 0.85. As mentioned in the user’s guide, please avoid any withstand voltage test.

Installation location and operating environment
Avoid installation in areas of high temperature, excessive humidity, or where moisture can easily collect, as well as areas that are dusty, subject tocorrosive gasses, mist of liquid for grinding, or salt. Install the inverter away from direct sunlight in a well-ventilated room that is free of vibration. The
inverter can be operated in the ambient temperature range from WJ series C1(ND):-10℃ to 50℃, WJ series C1(LD):-10℃ to 40℃. When theambient temperature ranges 40 and 50℃, the carrier frequency and the output current must be limited depending on the load type. Please refer to theuser’s guide.

Main power supply

Installation of an
AC reactor on the
input side

In the following examples involving a general-purpose inverter, a large peak current flows on the main power supply side, and is able
to destroy the converter module. Where such situations are foreseen or the connected equipment must be highly reliable, install an
AC reactor between the power supply and the inverter. Also, where influence of indirect lightning strike is possible,
install a lightning conductor.
(A) The unbalance factor of the power supply is 3% or higher. (Note)(B) The power supply capacity is at least 10 times greater than the inverter capacity (the power supply capacity is 500 kVA or more).
(C) Abrupt power supply changes are expected.
Examples:(1) Several inverters are interconnected with a short bus.
(2) A thyristor converter and an inverter are interconnected with a short bus.
(3) An installed phase advance capacitor opens and closes.
In cases (A), (B) and (C), it is recommended to install an AC reactor on the main power supply side.
Note: Example calculation with VRS = 205V, VST = 201V, VTR = 200V
VRS : R-S line voltage, VST : S-T line voltage, VTR : T-R line voltage

An inverter run by a private power generator may overheat the generator or suffer from a deformed output voltage waveform of thegenerator. Generally, the generator capacity should be five times that of the inverter (kVA) in a PWM control system, or six times
greater in a PAM control system.

Notes on Peripheral Equipment Selection
Wiring connections

Wiringbetweeninverter andmotor(1) Be sure to connect main power wires with R/L1 (Single-phase: L1),S/L2,T/L3 (Single-phase: N) terminals (input) and motor wires
to U (T1), V (T2), and W (T3) terminals (output). (Incorrect connection will cause an immediate failure.)(2) Be sure to provide a grounding connection with the ground terminal ( ).

Electromagnetic
contactor

When an electromagnetic contactor is installed between the inverter and the motor, do not perform on-off switching during running
operation.

Thermal relay

When an inverter is used with a standard applicable output motor (Hitachi standard three-phase squirrel-cage four-pole motor), a thermal
relay for motor protection is not required due to the internal electronic protective function. A thermal relay, however, should be used:• during continuous running outside a range of 30 to 60 Hz.
• for motors exceeding the range of electronic thermal adjustment (rated current).
• when several motors are driven by the same inverter; install a thermal relay for each motor.
• The RC value of the thermal relay should be more than 1.1 times the rated current of the motor. If the wiring length is 10 m or
more, the thermal relay tends to turn off readily. In this case, provide an AC reactor on the output side or use a current sensor.

Installing a circuit breaker
Wiring distance
Earth leakage relay
Phase advance capacitor

Install a circuit breaker on the main power input side to protect inverter wiring and ensure personal safety. Choose an invertercompatible circuit breaker. The conventional type may malfunction due to harmonics from the inverter. For more information, consult
the circuit breaker manufacturer.
The wiring distance between the inverter and the remote operator should be 20 meters or less. Shielded cable should be used onthewiring. Beware of voltage drops on main circuit wires. (A large voltage drop reduces torque.)If the earth leakage relay (or earth leakage breaker) is used, it should have a sensitivity level of 30 mA or more (per inverter).
Do not use a capacitor for power factor improvement between the inverter and the motor because the high-frequency components of
the inverter output may overheat or damage the capacitor.

High-frequency Noise and Leakage Current(1) High-frequency components are included in the input/output of the inverter main circuit, and they may cause interference in a transmitter,radio, or sensor if used near the inverter. The interference can be minimized by attaching noise filters (option) in the inverter circuitry.
(2) The switching action of an inverter causes an increase in leakage current. Be sure to ground the inverter and the motor.

Because a DC bus capacitor deteriorates as it undergoes internal chemical reaction, it should normally be replaced
every 10 years. Be aware, however, that its life expectancy is considerably shorter when the inverter is subjected tosuch adverse factors as high temperatures or heavy loads exceeding the rated current of the inverter.The
approximate lifetime of the capacitor is as shown in the figure at the right when it is used 24 hours daily (80% NDload).JEMA standard is the 5 years at ambient temperature 40ºC used in 12 hours daily.(According to the "Instructions for Periodic Inspection of General-Purpose Inverter " (JEMA).) Also, such moving parts as a cooling fan
should be replaced. Maintenance inspection and parts replacement must beperformed by only specified trained
personnel. Please plan to replace new inverter depends on the load, ambient condition in advance.
