Ok, I have a griz G0704 with a chinese ac servo and driver combo. Setup as step in mach3, works flawlessly, best money spent.
I'm trying to figure out how to setup mach3 to utilize the encoder for rpm read out and positioning for rigid tapping. I have 3 outputs for the encoder, I assume for each phase. They each have a + and - minus I assume for common and input on my board pins.

Mach3 literature is useless, and haven't found any from google, the many different ways I've searched.

Thanks in advance.
