A VFD is an entirely different thing from a static converter. A VFD actually generates true three-phase power. A "static converter" is a network of capacitors and relays that converts a three-phase motor into a capacitor-start capacitor-run single-phase motor. It does not, in and of itself, produce three-phase power (though it can be a component of a rotary converter). If you treat a static converter as a black box that takes single-phase power in one side and puts three-phase power out the other you will get into trouble.
BTW jogging is very hard on motors and controls.
Hence my comment. I burned up two starter capacitors before I twigged to the idea that I was the problem using the jog button while threading.
Live and learn!
