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 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 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 fan fault mean in Danfoss VLT AutomationDrive FC 360?
A fan fault warning on Danfoss DC Drives means the fan warning function, which checks if the fan is running or mounted, has detected an issue. Note that the fan warning can be disabled in 14-53 Fan Monitor by setting it to [0] Disabled.
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 does heat sink temperature low mean in Danfoss DC Drives?
If the heat sink temperature is low in Danfoss DC Drives, it means the frequency converter is too cold to operate.
What does 'Brake overload' mean on my Danfoss Controller and how can I fix it?
If the Danfoss Controller displays a 'Brake overload' error, it means that the power transmitted to the brake resistor over the last 120 seconds has exceeded the limit. To resolve this, try decreasing brake energy via lower speed or longer ramp time.
What does it mean when my Danfoss Controller displays a 'Torque limit' error?
If the Danfoss Controller shows a 'Torque limit' error, it means the torque has exceeded the value set in either parameter 4-16 Torque Limit Motor Mode or parameter 4-17 Torque Limit Generator Mode.
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.
