Hello all,
I bought a cheap VFD to fit to my lathe.
I have searched for info on similar installations to a student but came up with nothing. I also tried to find a wiring diagram but no luck.
As some of you kindly informed me the other day. I need to wire the VFD straight to the motor. But In order to keep the separate stop start lever and the directional lever functioning what do I do I must admit I’ve not had an in depth look at the electrics other than roughly tracing how it’s ran.
I did want to put a potentiometer in a useable place, maybe with an rpm dial as well. Something like this but maybe in a different place, if I can get it sorted then I can do this after.
Here are some pics of my lathe.
The three prongs are the power feed coming into the lathe. I was tempted to try and keep that and maybe the rotary on and off switch so I can wire in a single phase coolant pump.
The top rotary style switch is for the forward and reverse.
The lower is on and off.
This is the VFD I have.
