Re: Hurco KMB1 To Mach 3
DON'T SCRAP IT? If you decide its too much work I'll take it. Well atleast if you aren't to far away anyway.
Most VFDs 5hp (3.7kw) or smaller will run on a single phase or a 3 phase input. They are derated about 30% when run on single phase. There is no real special trick to hooking it up. Pick two input legs and hookup the two wires of your single phase. Some VFDs specify which ones those have to be. Run 2 hots, common and a ground to your cabinet, and you will have 220V for the spindle and the transformer most of us used to create our own DC power supply, and you will have 120V from either hot to common for anything you want to run on 110V like your computer and monitor. I wired a power strip inside my top cabinet so I could plug in things like the oiler timing clock, 5V power supply for my BOB, power for my spindle brake valves, etc.
Also, not all KMB1s are the same. Different layout, different spindle motor, etc. The first thing you need to do is see what you have.
