Hello I had a bad 24 volt power supply(this is the one on the right as you face the side cabinet)coutant hsh60u-13 and I had a guy try to fix it with a generic he had and I dont think he knew what he was doing and created different errors. He told me to send control to heidenhain (tnc 2500) and 350.00 bucks later was told control was perfect x!!##$$*. I am starting back at square one and I went ahead and bought the correct one off e-bay but I didnt see how the wires came off the original. Does anyone have one of these beasts and tell me what wires go where. And could you give me the correct tool holder and retention knob size. The manual said iso 40 is this the same as a cat 40? P.s I have a maintenance manual and parameters for control if I can make copies to help anybody.
