Fig. 9.24 Compensation time constant too large
If it is not possible to find a uniform compensation time constant for the various
radii and velocities, the average value of the derived time constants is used.
If it has been possible to achieve a good result with these time constants and the
constant compensating amplitude across the whole working range, i.e. for all re-
quired radii and velocities and for positioning, characteristic adaptation
(MD 1804*, bit 7) is no longer needed.
