I have a bridgeport CNC with a heidenhain 151 control I'am getting a alarm Measuring system defetive (A) AT one time I could power down and power back up and the alarm would go away. can not do that anymore? I have good 24vdc and good incoming 230vac. I swap X&Y motor cables to see if the alarm change but it did not? It would be nice if some could help Me out? Thanks Lee
cable, light bulb or crap in the encoder. motor cable is not involved with the encoder.
