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.
What to do if Danfoss VLT AutomationDrive FC 360 DC Drives show Overload T29?
Check the load connected to terminal 29 or remove short-circuit connection.
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 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 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.
