- check whether there is a DRIVE-CLiQ communication error between the Control Unit and the Motor Module
involved and, if required, carry out a diagnostics routine for the faults identified.
- check that the electrical cabinet design and cable routing are in compliance with EMC regulations (e.g. shield of the
motor cable and brake conductors are connected with the shield connecting plate and the motor connectors are
tightly screwed to the housing).
