Fault word according to the VIK-NAMUR denition (MELD_NAMUR)
Bit Signicance P no.
0 1 = Control Unit signals a fault p2051[5] = r3113
1 1 = line fault: Phase failure or inadmissible voltage
2 1 = DC link overvoltage
3 1 = Power Module fault, e.g. overcurrent or overtemperature
4 1 = converter overtemperature
5 1 = ground fault/phase fault in the motor cable or in the motor
6 1 = motor overload
7 1 = communication error to the higher-level control system
8 1 = fault in a safety-relevant monitoring channel
10 1 = fault in the internal converter communication
11 1 = line fault
15 1 = other fault
