When trying to move the x or z axis machine goes into alarm 55 Servo Lag Excess. Also goes into this alarm when I try to move either in manual mode. After reading in here I`m thinkingh it ahs something to do with the servor board. How can and what do i need to check to determine where the problem is. Thxs Mike
If you think it is the servo drive (MR-S..) try and swap it with another servo drive. Test the motor first to make sure it is not shorted though, but this most likely is not your problem.
