Positioning then relies on the position of the sensor to the scale, not the positioning sent from the feedback device mounted to the motor. If the gap is too great between the two, a following error fault could result. With scales, the finish of the cut is a good indicator if something is loosening up. Checking for Backlash Use the same procedure we did on the lathes to check for backlash, and remember the rules. Remove any backlash compensation from the control parameters.
Compensations can remove backlash electronically to a point.
Go into the indicator in opposite directions. The indicator should return to the original position. If you make a change in the parameters, always take notes on everything you do from the original amount to the final input. Now, go out there and tighten up that axis. We will also get much deeper into the mechanical repair and the effects of making changes.
