8A81h
Error during homing
configurable
Cause
Homing was interrupted, e.g. by:
–
Withdrawal of controller release.
–
Reference switch is beyond the limit switch.
–
External stop signal (a phase was aborted during homing).
Measure
Check homing sequence.
Check arrangement of the switches.
If applicable, lock the stop input during homing if it is not de

Measure
Check whether the limit switches are connected in the correct
direction of travel or whether the limit switches have an effect

Reference switch connected?
Check configuration of the reference switches.
Move limit switch so that it is not in the zero pulse area.
Check limit switch parameterisation (N/C contact/N/O contact.
