What to do if Danfoss VLT AutomationDrive FC 360 motor does not brake?
If the motor does not brake, it may be due to incorrect settings in the brake parameters or ramp-down times that are too short. Check parameter group 2-0* DC brake and 3-0* Reference limits.
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 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 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.
How to troubleshoot a Danfoss DC Drives motor not reaching maximum speed?
If the motor is not reaching maximum speed, it could be due to incorrectly set frequency limits or a reference input signal that is not scaled correctly. Program the correct limits for the frequency. Also, program correct settings for the reference input signal.
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 '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 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.
