 +This command sets the amount of time in milliseconds that it takes an axis motor speed to go from the start velocity to the maximum velocity and then back down again at the end of the move.  At a minimum, this acceleration / deceleration time must be greater than <wrap cmd> t_step </​wrap>​ (the amount of time it takes for the controller to go through one loop of its main execution code; the <wrap cmd> INFO </​wrap>​ command shows t_step).
 +
 +== Example ==
 +
 +<asi> $ AC X=50 Y=50 Z=50
 +:A
 +$ AC X? Y? Z?
 +:X=50 Y=50 Z=50 A</​asi>​
 +
 +The command in this example will make the controller take 50 milliseconds to accelerate the motors on each axis during a move command. ​ When the controller gets within 50 milliseconds of finishing the move, it will begin to decelerate the motors back down to the start velocity where the pulses take over to bring the axes within the pulse crossover position error.
