I recently got my 82 mc-500v with Yasnac mx1 control powered up. The previous owner had it sit for 10 years. I have reentered the parameters and all axis jog smoothly but I cannot get it to zero. The limit switches all work according to the dgn screen. When I try manually do it doesn't even decelerate just hit's the OT limit. If I try it with the g28 I just get axis not ready alarm. Any Ideas?
