Positioning
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 the table
below. When using command SetPositionShort or
GotoSecurePosition, data is automatically aligned.
The accuracy of Acc is derived from the internal
