Doc ID 023768 Rev 2
performing the minimum path (minimum physical distance) or forcing a direction (see
Figure 10).
Performed motor motion is compliant to programmed speed profile boundaries
(acceleration, deceleration, minimum and maximum speed).
Note that with some speed profiles or positioning commands, the deceleration phase can
start before the maximum speed is reached.
Figure 10.
Positioning command examples

Motion commands
Motion commands produce a motion in order to perform a user-defined number of
microsteps in a user-defined direction that are sent to the device together with the command
(see Figure 11).
Performed motor motion is compliant to programmed speed profile boundaries
(acceleration, deceleration, minimum and maximum speed).
Note that with some speed profiles or motion commands, the deceleration phase can start
before the maximum speed is reached.
