I have actually tried a new drive, new servo motor, different exlar cylinder, different cables.  Pretty much have changed every component at some point.  Managers are losing faith and wanting to go back to the old hydraulic motor on a screw jack - gotta figure this out.  Thanks for the replies and suggestions

Thanks - I will get the analyzer installed and give it a try but Im not sure that the problem is reality since i can move the axis so easily by hand while this fault is occurring.  The axis will fault when trying to move in either direction.  The motor has no problem moving this equipment for weeks - then i get this fault and lose a lot of production time.  Thanks for the suggestion.

I have recently installed an ultra 3000 sercos drive and an AB servo motor coupled by belt to an Exlar cylinder.  The application is setting a Planer head to Position and hold.  The application seems pretty simple but every once in a while When attempting a move the axis will get a FEEDBACK , FEEDBACK NOISE, MANUFACTURE SPECIFIC FAULT and will not reset.  I have watched a trend while resetting and the Torque feedback goes to max.  One would assume the axis is jammed but can be moved quite easily by spinning the Exlar by hand.  If the Torque is at max why is the motor not turning??  I have changed to another Ultra 3000 , tried different cables, and changed the motor.  It will work fine for awhile and then give us trouble again.
