- Off Cyclic communication is not (yet) running.
Note:
The PROFIdrive is ready for communication
when the Control Unit is ready for operation
(see LED: RDY).

Possible causes:
- The controller is not transferring any setpoints.
- For isochronous operation, there is either no GC (Global Control) transferred from the controller, or it has an error.
3)
Only encoders that are rated for a voltage of 24 V must be connected.
