How to check Motor phase V missing in Danfoss DC Drives?
- AAndrea GarciaSep 8, 2025
Turn off the Danfoss DC Drives frequency converter and check motor phase V.
How to check Motor phase V missing in Danfoss DC Drives?
Turn off the Danfoss DC Drives frequency converter and check motor phase V.
What to do if Danfoss DC Drives reports Motor phase U missing?
Turn off the Danfoss DC Drives frequency converter and check motor phase U.
What to do if Danfoss DC Drives show Over Current?
If the inverter peak current limit (approximately 200% of the rated current) is exceeded, turn off the Danfoss DC Drives frequency converter. Check if the motor shaft can be turned and verify if the motor size matches the frequency converter.
How to troubleshoot Mains phase loss in Danfoss DC Drives?
Check the supply voltage and supply currents to the Danfoss DC Drives frequency converter.
What causes Live zero error on Danfoss DC Drives?
Check the signal on terminal 53 or 54; it should not be less than 50% of the value set in 6-10 Terminal 53 Low Voltage, 6-12 Terminal 53 Low _Current, 6-20 Terminal 54 Low Voltage, or 6-22 Terminal 54 Low _Current respectively.
How to adjust Torque limit on Danfoss DC Drives?
Check the torque settings in 4-16 Torque Limit Motor Mode or in 4-17 Torque Limit Generator Mode.
How to troubleshoot Motor thermistor over temp in Danfoss DC Drives?
Check that the thermistor is connected correctly between terminal 53 or 54 (analog voltage input) and terminal 50 (+ 10V supply), or between terminal 18 or 19 (digital input PNP only) and terminal 50, if the thermistor or the thermistor connection is disconnected.
What does Control word timeout mean in Danfoss DC Drives?
If 8-04 Control Word Timeout Function is set to Stop and Trip and there is no communication to the frequency converter, a warning appears and the Danfoss DC Drives frequency converter ramps down until it trips, while giving an alarm.
How to resolve DC over voltage in Danfoss DC Drives?
If the intermediate circuit voltage exceeds the limit, the Danfoss DC Drives frequency converter trips after a time. Connect a brake resistor, extend the ramp time, activate functions in 2-10 Brake Function, or increase 14-26 Trip Delay at Inverter Fault.
What to do if Danfoss DC Drives reports Mains failure?
If the supply voltage to the Danfoss DC Drives frequency converter is lost and 14-10 Mains Failure is NOT set to OFF, check the fuses to the frequency converter.
