th Motor thermistor trip
24
Check regen inductor temperature
Check thermistor continuity
Set Pr 7.15 = VOLt and reset the drive to disable this function
thS Motor thermistor short circuit
25
Check regen inductor wiring
Replace regen inductor thermistor
Set Pr 7.15 = VOLt and reset the drive to disable this function
Unid.P Power module unidentified trip
110
Check all interconnecting cables between power modules
Ensure cables are routed away from electrical noise sources
