Under voltage fault
DC-link voltage is below the fault voltage limit of the drive.
S1 = DC-link too low during run
S2 = No data from power unit
S3 = Under voltage controller has been active and speed is ramped to zero with ramp
time 2.
Possible cause
Too low a supply voltage
AC drive internal fault
One of the input fuses is broken.
External charge switch has not been closed.
Correcting measures
•
In case of temporary supply voltage break, reset the fault and restart the AC drive.
•
Check supply voltage.
•
Check function of DC charge.
•
Contact your local distributor.

Input line supervision
S1 = Phase supervision diode supply
S2 = Phase supervision active front end
Possible cause:
1. Input line phase is missing.
Correcting measures
•
Check supply voltage, fuses and cable.
F11
Output phase supervision
Current measurement has detected that there is no current in one phase or one phase current is
considerably different from other phases.
Correcting measures
•
Check motor cable and motor.
F12
Brake chopper supervision
Brake chopper supervision generates pulses to the brake resistor for response. If no response is
received within set limits a fault is generated.
Possible cause:
1. No brake resistor installed.
2. Brake resistor is broken.
3. Brake chopper failure.
Correcting measures:
•
Check brake resistor and cabling.
•
If these are ok the chopper is faulty. Contact your local distributor.

Drive Under Temperature Fault
Possible cause:
1. Heatsink temperature is under
