Hi Everyone, this is my first post and I am asking for help. I have an old Mori MV-65 with the Fanuc 11m control and the spindle will not change rpm. It is stuck at approximately 4500rpm and will not change regardless of the command given (either override or mdi). I am new to diagnosing and repairing problems with cnc machines but i am eager to learn and try anything. I do not have any alarms (that I know of) and have read through the manuals many times with little to no resolution. Any help at better understanding these machines is greatly appreciated.
