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 to do if the Danfoss Controller displays a short circuit error?
If the Danfoss Controller indicates a short circuit, it means there is a short circuit either in the motor or on the motor terminals. For J7 units, if this alarm occurs on power-up, check whether power cables are mistakenly connected to the motor terminals.
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.
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 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.
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.
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 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.
