I would move the axis to the position it faults in and then power down completely and then, if the motor drive end is accessable, try turning it and see how free it turns, compare this to a point in travel where it does'nt fault out.
Just about the only thing usually to cause a motor to heat up without any apparent load is that it has not reached the final position for some reason, but it is still in the range of following error where an error is not detected.
