What does 'Earth fault' mean on my Danfoss Controller?
- RRebecca ZamoraAug 29, 2025
If the Danfoss Controller displays an 'Earth fault' error, it means there is a discharge from output phases to ground.
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 causes short circuit in Danfoss VLT AutomationDrive FC 360 DC Drives?
A short circuit error in Danfoss DC Drives usually means there's a short-circuit either in the motor itself or on the motor terminals.
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.
How to reduce acoustic noise or vibration in a Danfoss Inverter?
Acoustic noise or vibration in a Danfoss Inverter can be attributed to: * **Resonances, e.g. in the motor/fan system:** Check if the noise and/or vibration have been reduced to an acceptable limit. * Turn off over-modulation in `14-03 Overmodulation`. * Increase resonance dampening in `1-64 Resonance Dampening`.
What does DC under voltage mean for Danfoss VLT AutomationDrive FC 360?
A DC under voltage error in Danfoss DC Drives means that the intermediate circuit voltage has dropped below the 'voltage warning low' limit.
What does torque limit mean in Danfoss VLT AutomationDrive FC 360?
A torque limit error in Danfoss DC Drives suggests that the torque exceeds the value set in either 4-16 Torque Limit Motor Mode or 4-17 Torque Limit Generator Mode.
What does mains failure mean in Danfoss VLT AutomationDrive FC 360?
This warning/alarm is only active if the supply voltage to the frequency converter is lost and 14-10 Mains Failure is NOT set to [0] No Function.
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 to do if my Danfoss Controller displays a 'Mains phase loss' error?
If the Danfoss Controller shows a 'Mains phase loss' error, it means there is a missing phase on the supply side, or the voltage imbalance is too high. Check the supply voltage.
What does it mean when my Danfoss Controller says 'Inverter overloaded'?
If the Danfoss Controller is indicating 'Inverter overloaded', it signifies that the load has exceeded 100% for an extended period.
