Hello all
I have very old 3-axis mill with FANUC 0M-C control, and now I am facing strange problem.
When I execute M03, the spindle starts rotating very slow (around 2 RPM) no matter of speed setting.
I think the spindle motor and cotrol board are not damaged, because in tool changing cycle, the spindle positions itself quickly as allways, and also rotates the umbrella type magazine with normal speed as allways.
Before this problem appeared, I was setting some serial port related parameters, then uploaded the CAM enerated program. This program was the first which rotated the spindle so slow, although normal speeds like S1500 are only specified in it. Since then, I am not able to spin up the spindle in MDI, nor original programs which used to work, nor new programs, it still keeps its 2 RPM.
The machine suffered all settings loss, due to empty batteries, but we were somehow able to make it work (mostly) again.
I will be gratefull for any idea what can be wrong with it.
