Panasert MV 2F Problem ZL or ZR Axis DRIVER ALARM

Hi The machine run fine. Now I had the problem ZL or ZR driver Alarm. Turn on machine, everything is checked O.K I can be able to home the machine. When just start auto, the assembly or semi -auto. The machine is stopped, and show driver alarm ZL or ZR. Tried to lubricate rail and ball screw, checked all sensors and no luck. I even removed all feeders, but it still the same problem.

Please help, error code is NC0303. Also, in the Z axis P325C-11LED driver box, the RED LED lit up on OC (over current)

Thank you Sony Nguyen
