Cross Cutter
Features of the "Cross Cutter" prepared solution
Prepared Solution Servo PLC / ECSxA 1.1 EN 2-93
The following formula can be used to calculate scaling factors for load-side mounting of position
feedback (see Figure 39):

Caution!
For applications with position feedback on the load side, please note that the position
encoder must rotate in the same direction as the speed sensor! If there is not the same
rotating direction of the feedback systems the rotating direction must be changed with
codenumber C3637 by setting a negativ value.
Caution!
If you use the ECS Sytem: With the Parameterisable variant it is not possible to use an
absolute encoder because this encoder type uses the same input X8 as the frequency
cuppling via DFIN. If an absolute encoder is necessary in the application the user has to
use the programmable version of the prepared solution Cross Cutter and have to handle
the line feedback for example via CAN on its own.
