A big drawback to the VFD is that it will only drive one motor at a time. If you have any power feeds they will need a separate power source.
It wants to start and stop the motor. If you want to reverse the motor (like power tapping) you have to do it through the VFD.

I ran my machines on VFDs for years. A while back I bought an American Rotary phase converter and my world has been a much happier place.

We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.
