Diagnose & Remedy
0: Check that the motor is connected to the
inverter.
1-40: Check if motor data in P304-311 are correct.
Check what type of motor wiring is required (star,
delta).
1. Factory Reset and new parameterization
2. Change drive
Change drive
1. Check data
2. Change IO module
1. Check data
2. Change IO module
1. If fault persists, change inverter,
2. Contact Service Department
Check CB and communication partner
Check USS master
