Troubleshooting and fault elimination
Failures can be quickly detected and classified by means of display elements or status
messages via the MotionBus (CAN).
Display elements and status messages provide a rough classification of the trouble.
The chapter "11.3 Fault messages" (
238) contains notes on causes and deletion of
faults.
