I have a VFD that controls an AC motor which compresses air. It is an 30kW motor. I have set the parameters required to drive the motor and it runs the motor but not properly. During the test the lamps in the room start to vibrate,plus we measure voltage between phase-neutral it drops by 10V(not running motor 238V when running 228V). The VFD outputs 80 amps ,however it is 3-4 times of the current required by the motor. During the motor startup sequence 0hz - 50hz we can observe huge mechanical vibration, the motor was shaking so hard, it is not normal vibration.
The VFD's type:3G3RX
I don't know what to do at this point.
