What to do if motor phase V is missing in Danfoss DC Drives?
If your Danfoss DC Drives report that motor phase V is missing, remove the power from the frequency converter and check motor phase V.
How to troubleshoot a dark display or no function on Danfoss DC Drives?
If the display is dark or there is no function on your Danfoss DC drive, first, check the input power source. Also, inspect fuses or the circuit breaker and follow the recommendations provided. If the LCP has no power, replace the faulty LCP or connection cable. Ensure there isn't a shortcut on the control voltage or at the control terminals, and wire the terminals properly. Use only LCP 101 or LCP 102. Adjust the contrast by pressing [Status] + [?]/[?]. If the display is still defective, replace the LCP or connection cable. For internal voltage supply faults or defective SMPS, contact the supplier.
Why Danfoss DC Drives power on with red light?
If your Danfoss DC Drives show 'Power On' and the indicator is red, this typically indicates an IP Address Conflict. Resolve the IP conflict.
What to do if Danfoss DC Drives show External error DI2?
If your Danfoss DC drive displays 'External error DI2', this could be caused by a safety input connected to DI2 having an illegal signal level, or the sensor may be broken. To fix this, check that the configuration of DI2 (parameter 42-21 Type, subindex [0]) is set correctly and that the connected sensor is installed according to specification. You might also need to extend the discrepancy time for DI2 using the VLT® Motion Control Tool MCT 10 Safe Plug-in.
What to do if Danfoss DC Drives show an earth fault?
If your Danfoss DC Drives indicates an earth fault, it means there's current leaking from the output phases to ground, either in the cable between the frequency converter and the motor, or within the motor itself. The solution is to remove power to the frequency converter and repair the earth fault.
What to do for a brake chopper fault in Danfoss D9h DC Drives?
If your Danfoss DC Drives reports a brake chopper fault, and a short circuit occurs, the brake function is disabled. Remove power to the frequency converter and remove the brake resistor.
What causes 10 Volts low error in Danfoss D9h?
A '10 Volts low' error in Danfoss DC Drives can be caused by a short in a connected potentiometer or improper wiring of the potentiometer. Remove the wiring from terminal 50. If the warning clears, the problem is with the customer wiring. If the warning does not clear, replace the control card.
What to do if AMA interrupted by user on Danfoss D9h DC Drives?
If the AMA was interrupted by the user on your Danfoss DC Drives, try to restart AMA again.
What to do if motor phase W is missing in Danfoss D9h?
If your Danfoss DC Drives report that motor phase W is missing, remove the power from the frequency converter and check motor phase W.
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.
