VFD for a retrofitted Tree Journeyman 320 B

Hello all,

I just purchased this guy's cnc machine. www.cnczone.com/forums/vertical-mill-lat...-320-b-retrofit.html

He did a great job. Runs good etc etc. I Need to purchase a phase converter to run this at home. But I also want to buy a VFD to put on this as well. Machine has stock speed selction and motor with pulley system and H - L manual selection. I am under the impression that if I buy a VFD I can run the machine on regualar 220. Is it even possible to use a variable frequency drive with mechanical speed selection?

I am unsure of what I need to search for or where to even get started on deciding what to buy. I can just get a phase converter and run the machine, but i'd prefer to spend the money on doing the same thing, and making the machine better instead.

Thank you Andy. The machine is equipped with everything needed to read rpm. It just hasn't been programmed in yet. Waiting on the wiring diagram.

I will look further into this. I will reply back with questions on the next step.

Thank you

I also believe the only thing requiring three phase is the motor. The guy I bought the machine from will forward the wiring diagram and I willwill know 100%.
