What does it mean if my Danfoss Controller is showing a 'Current limit' error?
- LLisa WilcoxAug 28, 2025
If the Danfoss Controller displays a 'Current limit' error, it indicates a frequency converter overload.
What does it mean if my Danfoss Controller is showing a 'Current limit' error?
If the Danfoss Controller displays a 'Current limit' error, it indicates a frequency converter overload.
What does it mean when my Danfoss Controller displays 'Motor thermistor overtemperature'?
If the Danfoss Controller indicates 'Motor thermistor overtemperature', it means the thermistor or thermistor connection is disconnected.
What does 'Earth fault' mean on my Danfoss Controller?
If the Danfoss Controller displays an 'Earth fault' error, it means there is a discharge from output phases to ground.
What does 'Control word timeout' mean on my Danfoss Controller?
If the Danfoss Controller displays a 'Control word timeout' error, it means there is no communication to frequency converter.
What does 'Live zero error' mean on my Danfoss Controller?
If the Danfoss Controller displays a 'Live zero error', it means the signal on terminal 53 or 54 is less than 50% of the value set in parameter 6-10 Terminal 53 Low Voltage, parameter 6-12 Terminal 53 Low Current, parameter 6-20 Terminal 54 Low Voltage, and parameter 6-22 Terminal 54 Low Current.
What does 'No motor' mean on my Danfoss Controller?
If the Danfoss Controller indicates 'No motor', it means that no motor has been connected to the output of the frequency converter, or one motor phase is missing.
What to do if the Danfoss Controller shows an overcurrent error?
If the Danfoss Controller displays an overcurrent error, it means the inverter peak current limit has been exceeded. For J1–J6 units, if this happens when powering up, verify that the power cables are correctly connected to the motor terminals.
What to do if Danfoss DC Drives power fuses open or circuit breaker trips?
If the power fuses open or the circuit breaker trips, it could be due to a phase-to-phase short, motor overload, or loose connections. Eliminate any shorts detected. Review the specifications for the application to address potential motor overload. Ensure all connections are tightened.
Why is my Danfoss DC Drives motor running in the wrong direction?
If your motor is running in the wrong direction, it may be due to a motor rotation limit, an active reversing signal, or wrong motor phase connection. Program the correct settings for the motor rotation limit. Deactivate any active reversing signals. Change parameter 1-06 Clockwise Direction if the motor phase connection is incorrect.
What to do if motor current imbalance is greater than 3% in Danfoss VLT AutomationDrive FC 360?
If the motor current imbalance is greater than 3%, there could be a problem with the motor or its wiring, or with the frequency converter unit itself. Check the motor and its wiring to ensure they are in good condition. If the imbalanced leg stays on the same output terminal, it indicates a problem with the unit, and you should contact the supplier.
