I have a lathe machine with a Fanuc Series io Mate -TD.
The problem is that when I command a M03 S500 at high speed gear, the machine gives a spindle speed of 350RPM. If I comand a M03 S500 at low speed gear the machine gives a spindle speed of 90RPM.
I was thinking that it is a PID parameter problem.
Can someone help me on how to set the PID in this fanuc controller?
Can it be another problem other than the PID?
