Lost Motion versus Repetitive Positioning Accuracy

Postby om_tech_support_JT » Mon May 24, 2010 11:12 am

Q: What is the difference between lost motion and repetitive positioning accuracy?

A: Lost Motion is the amount of error moving to the same pinion/spur gear teeth combination from different directions. It can also be thought of as the system backlash.

Repetitive Positioning Accuracy is the amount of error found when repeatedly moving to the same pinion/spur gear teeth from the same direction.

Is there a way to reduce lost motion?

Sure. You can try approaching the same position from the same direction every time. For example, you may have to rotate the motor CW from its original position, then on the CCW move back to the original position, you'll need to command the motor to move past the original position, then back to it while approaching it CW. This method eliminates backlash.
