I have an error on the x axis servo.
I have tryed swaping a cnc board 720
I have tryed swaping ball screw encoders.
I have tryed swaping motor encoders.
I have tested as much wireing as possible.
I have replaced the compleat 3 axis drive unit.
I have changed parameters
But I still have a servo lag excess error. The machine is running but if I bump the rapid travel up over 30% then the machine will error out randomly over the next few minutes. The time it takes to error out is proportional to the rapid percentage. I have had the xaxis counter ballance tweeked in and fixed.
The mazak repair man refuses to come back and look at it. I have had him in several times for this problem. I Have gone through numerous checks with mits on the phone for several houres at a time.
I am leaning twards the ball screw is binding or some sort of physical problem is causing the ball screw to move harder than it is suppoze to.
Anyone have any thoughts?
I am sick of running this thing at 30 percent and the boss is getting upsett that I have not fixed it in several months.
The servo drive flips several codes for about .5 of a second and then resets itself. It gets a red hard stop error. but then if you hit reset on the control and then hit start the machine will then start again from the begining of the part, whith the red error still on the screen. The repair man said that this is just not possbible. I have also replaced the battery backup and reset the parameters from the factory specks.
