Angle encoder

Control loop with a rotary direct drive motor (torque motor)

The performance of a direct-drive feed axis
is significantly affected by the choice of
encoder for measuring the axis position.
Encoders employing the optical scanning
method feature distinctive benefits for theaccuracy, speed stability, and thermal
behavior of a feed axis.

Position error within one signal period∆xn+1

Furthermore, higher kV factors in theposition control loop of direct drive motors
permit larger control bandwidths and allow
the servo stiffness to be tuned. However,this also magnifies the influence of theencoder’s signal quality on positioning
behavior and control-loop behavior. Position
errors within one signal period adversely
affect the positioning accuracy and speed
stability of the motor. At low feed rates, thefeed motor, and thus the rotary axis,
reproduce the position errors within one
signal period. Because direct drive motors
exhibit a wider control bandwidth due tothe higher kV factor, they reproduce these
position errors over a wider speed range ofthe feed axis.

Position error within one revolution

Position error 

Along with the actual position, encoders indirect-drive feed axes also measure thecurrent speed. Due to the absence of
mechanical transmission elements
between the encoder and the motor, theseencoders must exhibit an accordingly highresolution in order to attain high-quality
speed control at low feed rates.

Speed controller∆xnDirect drive motors are being increasingly
used in many fields, particularly in themachine tool industry. Compared withgeared rotary axes, direct drive motors are
extremely low wear and low maintenance.
Without intervening mechanicaltransmission components, torque motors
also enable significantly higher dynamic
performance of the rotary axes. Thanks totheir direct torque delivery, significantly
higher accelerations and shaft speeds canbe attained. This is particularly beneficial in
5-axis simultaneous machining, where it istypically the rotary axes that limit the
speed of simultaneous motion. Higher
dynamic performance of the rotary axes
translates into uniform feed rates andincreased productivity.

A high line count and high signal quality are
key characteristics of the RCN series. With
these encoders, direct-drive rotary axes
exhibit low motor current noise andsmooth operating behavior. The high signal
quality of optical encoders therefore
permits better use of the performancepotential of direct-drive feed axes.

Motor current in A 

The speed controller calculates the nominal
currents that brake or accelerate the motorin accordance with the control error.
Inadequate encoder signal quality in the
direct-drive axis causes disturbances in theposition control loop and in the underlying
control loops, extending as far the current
control loop. This leads to high noise levelsin the motor current signal and, inparticularly bad cases, to unwanted highfrequency noise in the power train. The
loop gain must be reduced. The high noise
also causes increased power dissipation in
the motor. This results in greater heat buildup within the axis unit. Thermally induced
deformations in the axis structure mayarise, or greater machine cooling
performance may be required. To avoid
these problems, direct-drive feed axes callfor position encoders with small signal
periods and high signal quality.

Benefits of the new RCN encoders compared with thepredecessor models

High system accuracy
Thanks to the optimization (e.g., of thescanning characteristics), the new
RCN 2001 and RCN 5001 series areavailable in system accuracies of ±2”
and ±4”.
At the same wide mounting tolerances aspreviously (e.g., up to ±0.3 mm axially), thesystem accuracy takes the following typesof error into account:• Position error within one revolution• Position error within one signal period• Coupling-induced error
The RCN 8001 series remains available insystem accuracies of ±1” and ±2”.

Convenient measurement of the directdrive motor temperature
To prevent the overheating of direct drive
motors during operation, their temperature
is typically monitored. When combinedwith the HEIDENHAIN EIB 5211 or
EIB 5212 sensor box, the new series of
encoders enable evaluation of the winding
temperatures in direct drive motors. The
sensor box is installed in close proximity to
the direct drive motor and enables thedigitalization of the direct drive motor’s
temperature data close to the application.
The position data and the processed
temperature data are transmitted to thecontrol via the purely serial interface.

This yields the following practical benefits:• Reduced cabling• Purely digital transmission technology• Overload protection of the direct drive
motor by monitoring all three windings• Precise temperature monitoring throughcompensation of the transmission timing
behavior of the temperature measurement (with direct drive motors fromETEL)
• Increased cost efficiency by using thedirect drive motor up to its thermal load
limit

Optimized scanning
The scanning performance of the
RCN 2001, RCN 5001, and RCN 8001 is so
forgiving that liquid contamination or dropsof condensation have hardly any effect on
the scanning signals and thus the motor
control. This broadly prevents interruptions
to the machining process due to encoder
contamination.

High permissible shaft speedsWith a purely serial interface, shaft speedsof up to 3000 rpm are possible with the
RCN 2001 and RCN 5001. Speeds of up to1500 rpm are possible with the RCN 8001.
The permissible speed largely depends on
the internal encoder temperature, which is
influenced by the operating time, tempera­ture, and other factors. The operating
temperature is defined as the temperaturein the immediate vicinity of the encoder—but not at the encoder’s surface. To protect
the encoder from thermal overloads, the
new RCN encoders are equipped with atemperature sensor. This sensor measures
the temperature inside the encoder andtransmits it to the subsequent electronics.
If the temperature inside the encoder is
too high (90 °C), then an alarm is generat­
ed, and the machine control initiates
appropriate measures to protect theencoder from damage. When the EnDatinterface is used and the temperatureinside the encoder reaches 86 °C, a
warning bit1) is set in advance. This bit canbe used to trigger individualized machine
actions and avoid interruption of themachining process. Speed diagrams werecreated through analyzing the encoder
temperatures from tests at different
operating temperatures and shaft speeds.
The diagrams show the permissible shaft
speeds as a function of the operating
temperature (valid for up to 90 minutes ofuninterrupted operation). As a function of
the operating temperature, the green areas
represent the permissible shaft speeds at
which temperatures inside the encoder are
non-critical. In the yellow areas, the combi­
nation of speed and operating temperatureyield such a high encoder temperaturefrom the outset that the EnDat interface
generates a warning bit.2) At the red lines,
the encoder temperature is 90 °C, and an
alarm bit is set for an excessive
temperature.

Functional safety

With the RCN 2001/5001/8001 series ofabsolute angle encoders, HEIDENHAIN
offers the ideal solution for positionacquisition on rotary axes in safety-related
applications. In conjunction with a safe
control, these encoders can be used as
single-encoder systems in applications
with control category SIL 2 (as per
EN 61508) or Performance Level “d”(as per EN ISO 13849).
Reliable position transmission is based on
two independently generated absolute
position values and on error bits provided
to the safe control. The functions of theencoder can be used for numerous safetyfunctions in the complete system as per
EN 61800-5-2 (see table).

Table D8 of the EN 61800-5-2 standard forelectrical motors defines the loosening of
the mechanical connection between theencoder and motor as a fault requiring consideration. Since the control is not neces-sarily able to detect such errors, fault exclusion for the loosening of the mechanicalconnection is required in many cases.

Electrical connection

Safe encoder

Safe control

The RCN 2001/5001/8001 angle encoders
provide a safe absolute position value at all
times—including immediately upon switchon. Purely serial data are transmitted overthe bidirectional EnDat 2.2 interface.

Safety-related position
measuring system

Along with the data interface, the mechanical connection of the encoder to the motor
is also safety-relevant.

Safety-related position measuring system with mechanical connection and electrical interface

Fault exclusion for the loosening of themechanical connection
There are various ways of connecting theRCN 2001, RCN 5001, and RCN 8001
series for providing this kind of fault
exclusion. Whereas the housing or flange
is normally fastened with screws, special
factors must be considered for the hollow
shaft connection. For more information on
this topic and on deviating specifications,please refer to the following table.

Fault exclusion is thereby possible for theloosening of the mechanical connection
between the encoder and the machine
shaft or customer fastening components.
For designing the mechanical fault
exclusion for other purely customer-sideconnections, the following encoder torquemust be taken into account:
MMax = J · Þ + MFriction

J:	Moment of inertia of the encoder (forrotor or stator, see specifications) and of

Mounting with mechanical fault exclusion

The housing of the RCN is firmly
connected to the mounting surface of themachine component via a mounting flange
and centering collar.
Shaft coupling with ring nut
During mounting, the hollow shaft of theangle encoder is seated onto the machine
shaft. The catch, which is attached to theencoder’s front face, implements the fault
exclusion for the loosening of themechanical connection between theencoder and the motor. Fastening is thenperformed with the ring nut, which can beeasily tightened with the mounting aid(for accessories and their moment ofinertia, see Accessories on pages 25 and26).
Front-face shaft coupling
Particularly in the case of rotary tables, theangle encoder must be integrated into thetable so as to be fully accessible when therotor is lifted. The hollow shaft is connected
through the front-face threaded holes bymeans of special mounting elements
made for the given design (not included indelivery). For compliance with the radial
runout and axial runout tolerances, theinside hole and the plane surfaces must be
used as mounting surfaces for the frontface shaft coupling. Fault exclusion for theloosening of the mechanical connection
between the encoder and the motor isachieved with additional spring pins.

EIB 3392 S external interface box incable design
The EIB 3392 S allows encoders with the“EnDat22” ordering designation to beconnected to the DRIVE-CLiQ interface.

DRIVE-CLiQ is a registered trademark of Siemens AG.

EIB 5211or EIB 5212 sensor box
The EIB 5211 sensor box from
HEIDENHAIN, or the EIB 5212 withadditional switching outputs, is installed inclose proximity to the direct drive motor
and permits the digitization of motor
temperature data close to the application.
In doing so, the EIB 5211or EIB 5212
processes up to three temperature
sensors, determines the maximum
temperature value, and forwards thesedata to an RCN xxx1.
Depending on the direct drive motor, aspecially programmed variant of the theEIB 5211or EIB 5212 may be necessary:• Configuration of the temperature
sensors• A particular compensation value for thetransmission timing behavior of thetemperature measurement

26

The following sensor types can beevaluated:• KTY 84-130• PT 1000• PTC• PTC triplet
The maximum value is transmitted over anadapter cable (ID 1249072‑xx) to the angle
encoder while compensating for thetransmission timing characteristics. In
addition to the position data, this value isthen relayed to the control via the EnDat,
Fanuc, or DRIVE-CLiQ purely digitalinterfaces (e.g., via the EIB 3392 S externalinterface box in cable form). The sensor box
does not influence the encoder interface;
this means that the interface is determinedby the connected encoder.

Further information:
For a more detailed description of thesensor boxes, refer to the EIB 5000
Product Information document.
