Can anybody give me some advice on these motors?
I have 3 Fanuc 'red cap' servo motors model 20S and I need to drive these with brushless analogue amps. using a +/- 10 volt reference signal.
The motors don't seem to provide the standard 3 phase 'Hall effect' outputs. Does anybody know how to decode the fanuc encoder outputs into 3 phase commutation signals Ha,Hb,Hc or should I just replace the fanuc encoder with something like the 'Servo-tek' ST50 encoder which can produce both commutation and quadrature outputs.
regards
Mike
