What does parameter error mean on Danfoss DC Drives?
If your Danfoss DC Drives displays a parameter error, it means the parameter is out of range.
What to do if Danfoss DC Drives show an over current error?
If you are experiencing an over current error with your Danfoss DC Drives, it might be due to shock loading or quick acceleration with high-inertia loads. First, remove the power and check if the motor shaft can be turned. Also, verify that the motor size matches the frequency converter and that the motor data is correctly set in parameters 1-20 to 1-25.
How to troubleshoot earth (ground) fault in Danfoss VLT HVAC Drive FC 102?
If your Danfoss DC Drives report an earth (ground) fault, it means there is current from the output phase-to-ground. To resolve this, remove power to the frequency converter and repair the ground fault. Check for ground faults in the motor by measuring the resistance to ground of the motor cables and the motor with a megohmmeter. You may also need to reset any potential individual offset in the 3 current transducers in the frequency converter.
What to do when Danfoss VLT HVAC Drive FC 102 DC Drives show an internal fault?
