A-M-C A12A100 Servo Drive with SouthWestern Ind ProtoTrak Plus

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.

7I77 Analog out --> Drive REF IN+ (4)
7I77 GND --> Drive REF IN- (5)
7I77 ENA+ --> Drive INHIBIT/ENABLE (11)
7I77 ENA- --> Drive GND (2)
Drive +INHIBIT/ENABLE+ (12) --> Drive GND (2)
Drive -INHIBIT/ENABLE+ (13) --> Drive GND (2)
Sw1-5 Off

PCW, Many Thanks!! I apologize for all the confusion. Many thanks.

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.

 

Many thanks
