Just brought a secondhand cnc lath and I am getting a spindle error code 751 saying Alarm-35.
What happens is that the maxium spindle speed is 3,000 rpm if you try to start at full speed the alarm comes on. if you start below 2,000 and speed up to 3,000 then hit the stop button it goes alarm. All test have been from the key board not in the program,
Any suggestion appricated.
