What causes a motor current imbalance greater than 3% in a Danfoss Controller?
If the motor current imbalance is greater than 3%, it could be due to a problem with the motor or motor wiring. Try rotating the output motor leads one position: U to V, V to W, W to U. Alternatively, the problem could be with the frequency converter unit, in which case you should also rotate the output motor leads one position: U to V, V to W, W to U.
Why is the motor running in the wrong direction with my Danfoss Controller?
If the motor is running in the wrong direction, it could be due to a motor rotation limit, so program the correct settings. It could also be due to an active reversing signal, so deactivate the reversing signal. Another potential cause is a wrong motor phase connection.
What causes an intermittent display on a Danfoss Controller?
If the Danfoss Controller display is intermittent, it may be due to an overloaded power supply (SMPS) caused by improper control wiring or a fault within the frequency converter. If the display stays lit, check the control wiring for shorts or incorrect connections. If the display continues to cut out, follow the procedure for a dark display.
What should I do if the motor is not reaching maximum speed on my Danfoss Controller?
If the motor is not reaching maximum speed, it could be due to frequency limits being set incorrectly; program the correct limits. Another cause could be that the reference input signal is not scaled correctly; program the correct settings.
