you didn't said why you decide to change the motor
first try to dismount the coupling between the motor and the axis and run the motor 100% and check if something happend.
if nothing happendt han you have a problem in the axis ballscrew or slideway
abnormal current allarm is generated by the driver and not by the motor
i had one month ago this with huge vibration of the motor when it stand still.
when i installed a new driver i had on drive the abnormal current
so i had to change the motor too for that to work
so better try a new motor .
