Hi, I've got a problem with my Y axis on my Excel 810 after I crashed on the Y axis. I cannot do a zero return without getting an overtravel alarm. When it stops on the limit switch it the machine position shows it to be +.040.
It was kind of a hard crash that "tripped" the Y axis (unfortunately, nothing on the table gave way). While searching I found some information about servo couplings slipping in crash.
Any thoughts about how to diagnose and repair? Any help would be greatly appreciated. Thanks.
