Data Sheet
13.4 Acceleration and Deceleration
Sixteen possible values can be programmed for Acc (acceleration and deceleration between Vmin and Vmax). Table 10 provides the
obtainable values in full-step/s. 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 programmed in commands SetPosition and SetPositionShort is given as a number of (micro)steps. According to
the chosen stepping mode, the position words must be aligned as described in Table 11. When using command SetPositionShort
or GotoSecurePosition, data is automatically aligned.
