Answer Posted / jayaseelan
This will cause unnecessary wear on the contactor and
there will always be a slight delay while the inverter
initialises.ie.if contactor placed in between vfd and motor
response time of contactor gettting on is slow compare to
vfd response speed so return current wii affect the
electronic bords.thats y contactors not not used in output
of vfd.
