With DDL, after one initialization period the error for constant-speed motion will be reduced by a
factor of about 100 and the dynamic error by a factor between 20 and 90.
Figure 35: With DDL, one initialization cycle
With more DDL initialization periods, the dynamic error can be reduced by a factor of many
hundred.
