8.0 Positioning Data
8.1 Stepping Modes
One of four possible stepping modes can be programmed:
Half-stepping
1/4 micro-stepping
1/8 micro-stepping
1/16 micro-stepping
8.2 Maximum Velocity
For each stepping mode, Vmax can be programmed to 16
possible values given in the table below.
The accuracy of Vmax is derived from the internal 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.
8.3 Minimum Velocity
Once Vmax is chosen, 16 possible values can be
programmed for Vmin. The table below provides the
obtainable values in Full-step/s. The accuracy of Vmin is
derived from the internal oscillator.

Notes
(1) The Vmax factor is an approximation.
(2) In case of motion without acceleration (
AccShape
= 1)
the length of the steps = 1/
Vmin
.
In case of accelerated
motion (
AccShape
= 0) the length of the first step is shorter
than 1/
Vmin
depending of
Vmin
,
Vmax
and
Acc
.
