Heidenhain display

My friend has an old Bridgeport with a Heidenhain VRZ 731 two axis display that counts down but has stopped counting up. Has anyone a circuit diagram so that he can hopefully trace the fault . Many thanks John

John, If you find a circuit please could you post a link to the source. I have one of these displays which is working fine but one day it might not........

Has your friend tried swapping the scales between X & Y and does the fault move from once display to the other?

If the signal from one of the quadrature outputs has been lost then I would expect the display to count one way only.

good luck
