Time constant too large
Too large a time constant (MD32540) in the circularity test compensates the contour
deviations at the quadrant transitions. (Requirement: The optimum compensation value has
already been determined.) However, with too large a time constant, the compensation value
applies too long and results in an overcompensation at the next circular contour.
