Circularity test

The circularity test is used among other things as a way of checking the resulting contour
precision. It functions by measuring the actual positions during a circular movement and
displaying the deviations from the programmed radius as a diagram (especially at the
quadrant transitions).
Example
The following example refers to a drive with an HR valve.
● X1 axis: Moved in the horizontal axis by an electric drive
● Y1 axis: Moved in the vertical axis by a hydraulic drive
