6.2.3 System with motor encoder and position encoder
The optional position encoder is used as feedback for the position control and transmits
the position of slide or drive roll to the controller.
[6-3] Schematic diagram - feedback with separate position encoder
In this case, the actual position and speed values on the machine side result from
converting the position encoder position via the resulting gearbox factor (ratio of motor
speed to position encoder speed; display in C02531/3 ) and the feed constant ( C02524 ).

How to activate the use of a separate position encoder:
On the Application parameter
tab in the dialog level Overview  Drive interface  Machine parameter:
1. Select the "position control" in the Controller configuration list field ( C02570 ) in
order that the position encoder will be evaluated.
2. Select the position encoder available in the Position encoder list field ( C00490 ).
3. Select the gearbox ratio of the position encoder (ratio of load speed to encoder
speed) as a quotient (numerator/denominator) which results from the resulting
teeth number:
• Enter numerator in the input field Gearbox fact. numer. load (
C02522 ).
• Enter denominator in the input field Gearbox fact. denom. load ( C02523 ) .
4. If required, adapt the position encoder mounting direction via the list field Position
encoder mounting direction ( C02529 ). The position encoder mounting direction is
preset to "Encoder rotating CW".

Tip!
The resulting gearbox factor for the position encoder is displayed in
C02531/2 .
