Okay guys. I'm baaack.
Got it all wired up, and the controls are working (in testing) as expected. However, when i try to turn on the lathe i get about 1/2 inch of rotation and then an E.OV2. So...I removed all the circuitry i built and tried running it directly from the VFD. I checked the manual and it says that E.OV2 is "Regenerative overvoltage trip during constant speed" which is triggering the "Stall Prevention" circuit. Any kind words of wisdom?
FWIW, the motor has 9 black wires, 6 of which (in bundles of 2) were wired to a RPC, the 4th bundle which is comprised of 3 wires was just wire nutted together. When i wired the VFD i took UVW and connected them to the 3 2-wire bundles. I took the ground and connected it to the bundle of 3 wires thinking it was ground....maybe not?
