I am wanting to use a VFD to control a 3 phase, 3hp motor, I have a single phase motor I want to be running at the same time. I want the pair to run for a given amount of time, lets say 30 minutes, then both shut off. I was thinking I could put a spring wound timer ahead of the VFD where
I would wind up the timer which would start the single phase ( fractional hp ) motor and power up the VFD, then I would start the VFD. When the timer wound down it would cut the power to both.
My concern is as to whether or not this would damage the VFD or if there is a better way to do this?
