Dual Positioning
perform a positioning using two different velocities. The first
motion is done with the specified Vmin and Vmax velocities
in the SetDualPosition command, with the acceleration
(deceleration) parameter already in RAM, to a position
Pos1[15:0] also specified in SetDualPosition.
Pos1[15:0] + Pos2[15:0] is done at the specified
Vmin velocity in the SetDualPosition command (no

already ongoing is not recommended.

movement direction in such a way that the traveled distance
is minimal.
