Hi everyone,

I have electrical problem with Maho MH 600 P 1978 year of production - Heidenhain TNC121 and I need wiring diagrams to fix this problem. Could anybody help my in this subject?
Motors working fine and all function from electrical cabinet but not from steering panel. I thinking that is some protection in way from cabinet to panel. I already checked relays, fuses, contractors, transformer and other equipment all looks ok. But should be something to protect starting engine like limit switches (also checked) or something else but what I don't know.
Hydraulic breakers, clutches, potentiometer, emergency stop button working from panel, only engines start buttons and hydraulic changing tools not working.

Many thx for any help
Kris

Did you fix your problems with this machine? I have just purchased a Maho Mh700 1978 model and have some drawings.
