6.7.1
Constant speed commands
A constant speed command will produce a motion in order to reach and maintain a user-
defined target speed starting from the programmed minimum speed (set in MIN_SPEED
register) and with the programmed acceleration/deceleration value (set in ACC and DEC
registers) (see Figure 14). A new constant speed command can be requested anytime.

Constant speed commands examples
6.7.2
Positioning commands
An absolute positioning command will produce a motion in order to reach a user-defined
position that is sent to the device together with the command. The position can be reached
performing the minimum path (minimum physical distance) or forcing a direction (see
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 starts
before the maximum speed is reached.
