Quadrant error compensation

Quadrant error compensation

Quadrant transitions without compensation

Quadrant transitions with quadrant error compensation

Function

Quadrant error compensation (friction compensation) ensures a much higher degree of contour precision, particularly when machining circular contours. At the quadrant transitions, one axis traverses at maximum path velocity while the second axis is stationary. The different friction conditions can cause contour errors.

Quadrant error compensation reliably compensates for this behavior and produces excellent results, without contour errors, in the very first machining operation. For operator-controlled quadrant error compensation, the intensity of the compensation pulse is set according to an acceleration-based characteristic. This characteristic is determined and parameterized during commissioning with the aid of the circularity test.
