Data Sheet
13.4 Acceleration and Deceleration
Sixteen possible values can be programmed for Acc (acceleration and deceleration between V
min
and V
max
). Table 9 provides the
obtainable values in full-step/s2. One observes restrictions for some combination of acceleration index and maximum speed (gray cells).
The accuracy of Acc is derived from the internal oscillator.

13.5 Positioning
The position is programmed in the command
SetPosition
and is given as a number of (micro)steps. According to the chosen
stepping mode, the position words must be aligned as described in Table 10. When using command
GotoSecurePosition
, data is
automatically aligned.
