So now that the ease of use wish list is satisfied, next the designer will talk about optimizing motion. Jerk is the rate of change of acceleration. Jerk is important to consider in applications where fragile objects could be damaged, such as: Elevators, Conveyor Belts, and Cutting Tools. Shown here on the graph that as one decreases the jerk of the system, the smoother transitions. Applications that do not need to transition speeds as fast as possible can benefit from smaller jerk. Lower jerk can reduce the maximum current.
