That is the universal resolver/encoder board that Aerotech uses, I have the colour code
some where, what is the full part number of the motor?
For differential hook up it is.
COS-N = /B
SIN-N = /A
COS = B
SIN = A
MKR = Z
MKR-N = /Z
If a resolver, you will not see a 0-5v transition on any of the signals like you will on an encoder, also there is no marker pulse on a resolver.
