When you use an S-curve profile, jerk determines how fast an axis can change its 
acceleration and deceleration. 
•  An S-curve profile has to get acceleration to zero before the axis can slow 
down. 
•  The time it takes depends on the jerk, acceleration, and speed. 
•  In the meantime, the axis continues to speed up. 
The following trends show how the axis stops with a trapezoidal profile and an 
S-curve profile.
