A friend of mine is looking for a vfd with an integral contactor so that as soon as he starts the motor on his machine he can command an unrelated circuit to either open or close and vice versa (Not sure of the exact operation but it doesn’t matter). i guess he can’t command a relay from one of the phases downstream of the vfd because it will interfere with the vfd performance. Does such a thing exist? Is there name for this feature that we could search for? My google fu has not been successful.
