I have a question around this topic I think, my lathe was a single phase 220v 2hp motor with a mag reversing starter that you controlled by a lever under the front of the carriage, down was forward and up was reverse. I am changing this setup to a VFD, I have increased the motor to 3hp, purchased a IMO Jaguar VFD of the correct size for the motor, the motor is a VFD rated motor and I have a remote control station that has run, forward, reverse, stop, jog and a pot for speed on it. My question is can I use the existing mag starter to send the power to the VFD so that I may continue to use the original switch or will I ruin the VFD by interrupting the feed line to it ? The VFD is a 240v 1ph input to a 240v 3ph motor.
