oscillator. Under special circumstances it is possible to
change the Vmax parameter while a motion is ongoing. All
16 entries for the Vmax parameter are divided into four
groups. When changing Vmax during a motion the
application must take care that the new Vmax parameter
stays within the same group.
Micro−stepping

For each stepping mode, the maximum velocity Vmax can
The accuracy of Vmax is derived from the internal
