Fault 6 Line fault
Subfault: 6.1 Description: Line phase failure | ||
|---|---|---|
| Response: Line phase failure | |
Cause | Measure | |
Missing line phase detected. | Check the supply system cable. | |
DC link voltage periodically too low. | Check the configuration of the supply system. | |
Inadequate line voltage quality. | Check the supply (fuses, contactor). | |
Subfault: 6.2 Description: Power failure | ||
|---|---|---|
| Response: Power failure | |
Cause | Measure | |
Power failure detected. | Check the supply system cable. | |
Subfault: 6.3 Description: Line overvoltage | ||
|---|---|---|
| Response: Emergency stop + output stage inhibit | |
Cause | Measure | |
Line voltage exceeds permitted upper threshold value. | Check the nominal line voltage used in the project planning. | |
Inadequate line voltage quality. | Check the quality of the power system. | |
Subfault: 6.4 Description: Line undervoltage | ||
|---|---|---|
| Response: Line undervoltage | |
Cause | Measure | |
Line voltage dropped below permitted lower threshold value. | Check the nominal line voltage used in the project planning. | |
Inadequate line voltage quality. | Check the quality of the power system. | |
Supply system cable missing. | Check the wiring. | |
