1
0
Memory error – motor parameters lost
Contact manufacturer/technical support
2
0
Short circuit – electronics power
module damaged
Board damaged – replace board
3
0
Motor synchronization lost – wrong motor parameters
or electronics damaged
Check motor windings.
If motor windings OK (all 3 windings have same resistance),
replace board.
If motor windings damaged (open/short circuit), replace motor.

32
Over voltage: supply voltage above 565Vac (DC bus
voltage over 800V) during motor running
Check power supply voltage
check power supply wiring
4
33
Under voltage: supply voltage below 212Vac (DC bus
voltage below 300V) during motor running
Check power supply voltage
check power supply wiring

(check input register 15)
Check if operating temperature is above rated maximum operating
temperature.
Check mechanical load for anomalies (e.g. difficult turning)
4
114
Motor windings temperature over 125°C
(check input register 16)
Check if operating temperature is above rated maximum operating
temperature.
Check mechanical load for anomalies (e.g. difficult turning)
