Example 2

The user has initiated a movement at a certain speed in a certain direction. The user would now like to rapidly reduce this speed in a particular situation. To achieve this, the user specifies a new lower speed for the lrVelocity input variable and a large jerk via lrJerk. As a result, the maximum deceleration with which the speed is reduced quickly accumulates with the large specified jerk.

Even before the speed has reached the specified value, the user decides to increase the speed again. To achieve this, the user specifies a higher speed for the lrVelocity input variable but a significantly smaller jerk via lrJerk. As a result, the deceleration reduces relatively slowly with the small jerk now set such that negative acceleration is effective for a certain period. This means that the speed may be negative, i.e. the drive reverses.

The diagram below illustrates this scenario.
