21-820 Rockwell Power Feed Control Help?

Post by prmckay1 » Thu Jul 26, 2018 1:42 am

friend has a 21-820 power feed on a rockwell mill.

Controls and motor were fried

Motor has been rebuilt, but now issue is controls.

it appears there may have been an updated circuit board 438-01-307-0100 (we think that is correct from the schematics we have found

but - can't find source.

either source of the updated circuit board or an original wiring diagram are what we are needing help in finding
