I would like to offer my many thanks the forum, the moderators and all the members that make this forum so informative. I am working on a basic 2 axes mill that started life as a prototrak plus. This originally used "back EMF" as feedback with A-M-C 12A8 drives. Many thanks for all the great help.

The A15A100 seems to have encoder velocity feedback rather than tachometer
so needs the encoder connections in your drawing (well possibly with A/B swapped
depending in the exact encoder used)

PCW, Many, many thanks, I have a diagram of what I believe to be what you have described, just wondering if this looks proper? Many thanks I offer the following diagram for others using the A12100 driver.
