Separate, but related, concepts
High Accuracy AND High Repeatability
|Accuracy is the ability of a linear actuator to reach a commanded position. if an actuator is highly accurate, it will exhibit a high degree of repeatability as well.
High Repeatability, but Lower Accuracy
|Rebeatability is the ability of a linear actuator to reach the same position time after time. Repeatability is often what’s needed in an application rather than accuracy.
Lower Accuracy and Lower Repeatability
|There are applications where positioning tolerances are wider. In those instances lower degrees of accuracy and repeatability are acceptable.
