Hello am facing some issues that need help pls, i have ABB ACS350 2.2KW VFD, and 0.33HP 3 phase Induction motor, after setting the parameters as required, and the vfd is set for operation, send power to the motor i wittiness a continues vibration and the motor rotor trying to run,
please what could be the cause and how can this be rectify

will appreciate any help thanks.

mikerj:
The symptoms suggest one of your phase windings may be open circuit, either within the motor, in the wiring between motor and VFD or the VFD itself is bad.

CatalinaWOW:
Be sure to double check your wiring.  I have found the circuit diagrams/instructions provide with some three phase motors to be subject to misinterpretation.

Single Phase Induction motor needs a new winding. Does it has a single layer or double layer winding, may be you need to just change single layer.
