I also agree with Ed on mounting your VFD head remotely if you have that option available. That is what I did on my lathe also but I am using a different VFD.

The thing is, your VFD could be installed pretty easily if you replaced your original switches with simpler ones that have minimal connections. But I understand the reason for wanting to retain the original controls, I did it as well. But that comes with a price. To be able to do that you really need to fully understand what each and every circuit does, and how they interact with each other. To use your original FWD/REV switch requires passing high voltage circuits and low voltage circuits through the SAME switch. If they get mixed together you can kiss your entire electrical system goodbye. It can be done. But 'experimenting' will not end well I promise you.

I went so far as to add an extra circuit to mine that allows me to switch back and forth between the VFD control panel and the original lathe controls with the flip of a toggle switch on the side of the VFD enclosure. But not all VFD's can do that.



Oh, and your MachTach will NOT be wired into your VFD. It will need it's own circuitry. There are a number of us here that own them I believe. Henry makes a great product. I have mine installed on my mill.

THX . I have done a lot of wiring with reversing etc.. but not understanding the way the switches are configured I am at a loss
I looked at the vfd software and I am lost again
