Effect of friction compensation

Friction compensation reduces position lag and axis backlash. This boosts accuracy. Furthermore, the speed controllers are relieved, as a result of which the dynamic parameters can be used to a greater extent without impairing the machining result.

The figure below shows the result of a circular transition test with compensation activated and deactivated. Without compensation (blue), clear peaks are visible at the quadrant transitions, which are reduced by compensation (red).
