On which head you get the alarm (HD1 or HD2)???
Have you check coupling between motor & ball screw??? If it is fine change your controller (I think RG221B or A) from head 1 or 2, to head 2 or 1 and see if alarm goes from one head to another head then your drive controller is not good.
Let me know by result, I had also few times same alarm on my few different MPX but every time the problem was different than the other one.
