I am trying to drive a Fanuc DC servo, a 6M, with an Allen Bradley drive, AB 8400 system. Wondering what that servo has for it's position feedback, is it an encoder, a resolver or? The servo has the same voltage as the AB, 150 VDC so that part of it is good, and it is also a brush type so good there too. I believe my AB system uses encoders, how would I tell for sure? Thanks for any help, DaveA.
