Fig. 9.22 Compensating amplitude too high

If the compensation time constant used in the circularity test is too small, the test

shows that the radius deviation is compensated for, for a short time at the qua-

drant transition points, but that larger radius deviations from the programmed ra-

dius again occur immediately after (see Fig. 9.23).

Fig. 9.23 Compensation time constant too small

If the value for the compensation time constant chosen for the circularity test is

too high, we see that the radius deviation at the quadrant transition points is com-

pensated for (it is assumed that the optimum compensating amplitude has been

found), but that after the quadrant transition point the radius deviation is less than

the programmed radius (see Fig. 9.24).
