    Default Lb 15 spindle runs at half speed and backwards

    Can someone help me I may have lost a parameter or something. I ran a batch of parts and everything seemed to be going good. Then a few days later I was setting up on a new job and noticed that the spindle was running at half the speed i programed it to and was running in the opposite direction. Ex: M3 S1000 is now running ccw and 500 rpm. It is an early 80s machine with an osp 5000 control and has a fancy spindle drive

    What should I look for to remedy the problem. Could it be the pulse generator the spindle drive or could it be a parameter somewhere. Or does it sound like an electrical issue . Could it be one of the ice cube relays

    ive found that when i hit M41 it respects the S2000, when i do M42 and hit S2000 it actually does 4000rpm.. but i have alot of other issues in my machine.. what i mean to say is check that it actually are in the right gear. ?
