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 to do if Danfoss Inverter motor is not reaching maximum speed?
If the motor connected to your Danfoss Inverter isn't reaching its maximum speed: * **Frequency limits are set incorrectly:** Program the correct limits. * **Reference input signal not scaled correctly:** Program the correct settings.
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 Danfoss Inverter has open power fuses or circuit breaker trip?
If the power fuses are open or the circuit breaker trips in your Danfoss Inverter, it could be due to: * **Phase to phase short:** Eliminate any shorts detected. * **Motor overload:** Perform a startup test and verify that the motor current is within specifications. If the motor current exceeds the nameplate full load current, run the motor with a reduced load and review the application specifications. * **Loose connections:** Tighten any loose connections.
What does 24 V supply low mean in Danfoss VLT AutomationDrive FC 360 DC Drives?
If the 24 V supply is low in Danfoss DC Drives, the 24 V DC may be overloaded.
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.
