I can't say for certain without knowing more about exactly what you have but Fanuc of that era should use ordinary encoders, fed directly to the control, the control then sends a synthetic analog tacho singnal and analog control signals back to the servo amps, which are fairly ordinary DC servo amps and motors.

I just went to look at a '80s Bridgeport VMC with Heidenhain controller and Fanuc yellow cap servos (didn't get inside a cabinet for closer investigation - yet). The beast has a tool changer and a bad controller. Anyone have experience with that particular configuration? Particularly, what servo amps were used and what encoder technology - I remember discussions about Fanuc hardware that suggested that specialized interface hardware is necessary. What about tool changer technology - I assume a PLC process in the LCNC environment would be sufficient to get that running. It's probably just a passing fancy, but oh my it's a temptation.
