So I got everything to work! it seemed that the big hang-up was the Field Failure relay not closing. With the main contactor. I nudged the contacts closed with a piece of wood while depressing the Start button and everything lit up like Rockafeller Plaza at Christmas! Now the field failure relay closes the way it's supposed to. It's worth noting there's a bit in the 10ee manual for the modular drive that mentions adjusting the sping tension on the field failure relay if it's not closing. I imagine I just overcame some mechanical stickiness that was keeping it from closing properly.
I had something similar in my WiaD drive, dried oil was holding a relay closed longer than it should. I ended up cleaning all my relay pivots and stops with some cotton buds and solvent - I recall using toluene b/c I couldn't get MEK right away.
I'm sure I've made some assumptions that are wrong about how the WIAD works or even fundamentals about electricity, but if someone came in and corrected those assumptions, I'd be super grateful.
I didn't see anything horribly wrong.
Some other things I'm curious about: The schematic for the modular drive identifies a section as the "Phase Shift Circuit. What exactly does that do, and is there a part of the WIAD that serves the same purpose?
It's just the armature voltage supply.
