10.3.10 Fault Code 10 - Output Phase Loss
Cause
The software detects that the output phase from the drive to motor is disconnected.
System default operation: Coast stop. System operation is configurable.
Troubleshooting
•
Check if the output cables are loose or disconnected.
10.3.11 Fault Code 11 - Output Grounding
Cause

Cause
During 10 minutes of continuous running time, the output imbalance is above 15‰ for a cumulative time of more than 30 s.
System default operation: Alarm. System operation is configurable.
Troubleshooting
•
Check that the capacitance of the DC-link capacitors matches the specifications.
•
Check that the voltage of the transformer secondary windings is balanced.
10.3.13 Fault Code 13 - Output Phase Imbalance Fault
Cause
The output imbalance is above 30‰ for over 1 s.
System default operation: Coast stop. System operation is configurable.
Troubleshooting
•
Check that the capacitance of the DC-link capacitors matches the specifications.
•
Check that the voltage of the transformer secondary windings is balanced.
10.3.14 Fault Code 14 - Output Underload
Cause
The software detects the motor operating in the underload area for longer than 20 s.
System default operation: Not detected. System operation is configurable.
Troubleshooting
•
Check if the load of motor is too light.
