When several motors connected in parellel with a VFD can we turn ON/OFF any of the motors ?

It is not allowed to switch ON or switch OFF of individual motor from parallel connected motors. All the motors must be connected with VFD before giving the RUN command. During running if you switch OFF or switch ON any of the motors with VFD will cause tripping and repeatedly doing this operation by ignoring the trip may damage the VFD. Hence this kind of operation is not recommended.
