Subfault: 23.4
Description: Hardware fault
Response: Output stage inhibit
Cause
Measure
A fault occurred in a hardware component of the
power section, e.g.: Overcurrent hardware com-
parator.
– Check the current supply.
– Increase the ramp time.
– Check for correct motor size (the motor current
is too high).
– Contact SEW-EURODRIVE Service.
