12.10.45 Fault 10 - Input line supervision, Subcode S1 - Phase supervision diode supply
Cause
The input line phase is missing.
It is possible to set different responses in the application for this fault. See parameter group Protections.
Troubleshooting
Do a check of the supply voltage, the fuses, and supply cable.
12.10.46 Fault 11 - Output phase supervision, Subcode S1 - Common output phase supervision
Cause
The measurement of current tells that there is no current in 1 motor phase.
It is possible to set different responses in the application for this fault. See parameter group Protections.
Troubleshooting
Do a check of the motor cable and the motor.
12.10.47 Fault 11 - Output phase supervision, Subcode S2 - Additional closed loop control output
phase fault
Cause
