Our 2000 Hardinge with OMD control has had Y axis issues for the 3rd day in a row.
Each day for the past three days, it works perfectly for a few hours and then in the afternoon starts to move extremely coarsely and vibrates the shop floor and the load meter is all over the place, and won't move at all half of the time (the position display moves, though) and throws a 421 or 420 error (Y axis excess). Sometimes it won't move with the handwheel and then will jolt half an inch or so and have a 424 (Y axis detect error) and/or 401 (VRDY off?).
This morning the repair tech came in and it ran perfectly for a few hours, including jogging back and forth at 1181ipm for a few minutes, and now it will barely move at all and when it does it sounds terrible.
The ballscrew turned fine by hand, and I greased it up again yesterday and took off the covers and looked around and everything seemed decent. It seems almost like mechanically it's fine but electrically it's fighting with itself.
We replaced the XY module in the control a few months ago, if that makes a difference.
How does one troubleshoot this? What is a likely cause?
