I'm going to differ to somebody else on your motor wires. I *think* just wire the VFD outs to one set or the other. It won't hurt to try. I'll guess one set is "lo" and the other is "hi"
There are several ways to wire your control. lets decide exactly what you want. My favorite method is to have a start and Estop for the whole machine. Push the big red stop button and kill everything. If you have nothing else like power feed, coolant, etc. you may not feel this is necessary. I spent too many years as a corporate slave where this is required on all machines. Any fool knew how to turn off any machine as they all had this.
For the VFD driving the spindle, I like a three position rotary switch, left is CCW, center is off, right is CW. really handy if you want to do things like power tapping. A plus, this is easy to wire with no additional relays needed.
Or we could have a start CW, a start CCW, and a stop button.
Or we could have a rotary switch for CW or CCW, a start and a stop button.
All of the above use a pot for speed control
I'll be glad to walk you through any of these options. Do you read ladder logic?
