6.7.3 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 
The 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.

6.7.4 Stop 
commands
A stop command forces the motor to stop. Stop commands can be sent anytime.
The SoftStop command causes the motor to decelerate with a programmed deceleration 
value until the MIN_SPEED value is reached and then stops the motor maintaining the rotor 
position (a holding torque is applied).
