I have found a manual online. It is a fanuc encoder on the top of a spindle motor.
I don't seee any trim pots inside the box. Just 5 jumpers. 1is it for 90 or 270 deg for reference. 2nd is high or low impedence input. (not sure what this does) 3-5 is interpolation amount (5x vs 10x) and output frequency settings.
