I have a VFD on the way for my SB lathe. The lathe currently has Start, Reverse and Stop on a box mounted to the top of the lathe. This box is wired to a box on the rear of the lathe which has the relays and whatnot to do those things. The power is supplied to a pigtail with a 220 twist lock connector on it. My plan was to mount a similar pigtail to the output of the VFD and then just plug in the lathe when I want to run it. I also bought a mill which uses an identical plug, so when I get it running I will plug it into the output of the VFD using the same pigtail.
I figure I will not be using both machines at once so why hardwire everything.
The concern I have it that I read somewhere that you must use the VFD controls for off and on, etc., and that switching off the power between the VFD and the lathe will kill the VFD. Does this apply to my situation? If so, I might as well take the controls off of the lathe and just make a remote from the VFD.
Am I thinking this out correctly? I don't want to fry my VFD....
