Dear colleagues,

I have a problem with an old MAHO 600W machine. The machine suddenly stop's and message "SPINDLE AND FEED STOP IPC PIN4" on the top of the display. The machine can move over the axes manually and can turn the spindle only in manual mode. Once trying to switch to run the program in AUTO mode the FUE light on INDRAMAT TRK6 4U lights up and and machine stop with above message again. When leave the machine switched off for 10-15 minutes it can be start again. The program runs for maybe 10 minutes and than stops again. Do sombody have the same problem and how it can be solved. PLease give us some idea where could be the problem. We have checked the required voltages on indramat TRK6 and it seems that all is OK there. Now lookiing for IPC module and connection. Teh machine control is CNC234 Heidenhein. Uploading some pictures for refference. Please, if someone have an idea about this problem please, let us know. Thank you in advance !
