Hi,
Please tell me what can be done.
Chiron FZ18S 5-axis 1995 Siemens 810M. The spindle does not start in AUTOMATIC and MDI-AUTOMATIC modes.
The machine has been idle for a long time, now we have carried out an inspection, changed all the air seals and cuffs on the cylinders and are trying to get it working. The machine turns on, zeros and moves along all axes.
When we try to turn on the spindle with the command “M3 S500 LF” in MDI-AUTOMATIC mode, the command is accepted (no errors appear), but the spindle does not rotate.
The situation is similar in AUTOMATIC mode. We work through the program step by step, we reach the line with the spindle start, the spindle start command is “worked out”, and the next step (next line) begins. In this case, the spindle does not start, no errors appear and program execution is not interrupted.
We can run the spindle in JOG mode. And after we have launched it in JOG, if we leave it turned on and go into MDI-AUTOMATIC mode, then we can use commands to change the spindle speed, direction of rotation (commands M3/M4), or stop it with command M5, and then run again.
