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).
Ø Factory Reset and new parameterization.
Ø Change inverter
Change inverter
Ø Check data
Ø Change IO module
1. Check data
2. Change IO module
1. Acknowledge fault
2. Change inverter if repeated
1. Check connections to the
communications board
2. Check the master
1. Check connections to the
