Achieving Positioning Accuracy Goals

Sept. 17, 2007
In this paper, you will learn that motion control systems are only as accurate and repeatable as each component that comprises them.

Choosing the correct mix of motion control components for a successful servo positioning system involves a combination of art, science, and experience. You need to fully comprehend the principle of operation, accuracy, resolution, and repeatability of each component in the system. Unfortunately, some of the errors that contribute to system inaccuracy are not easily observable, yet, they are measured empirically.
