Jerk limitation
Acceleration and deceleration can change suddenly if jerk limiting has not been activated.
The diagram below shows the traversing profile when jerk limitation has not been activated.
The diagram shows that maximum acceleration (a

switches to the constant velocity phase.

Jerk limitation can be used to achieve a ramp-like change of both variables, which ensures
"smooth" acceleration and braking as shown in the diagram below. Ideally, acceleration and
deceleration should be linear.

permanently, set parameter p2575 ("Active jerk limitation") to 1. In this case, limitation
cannot be activated or deactivated in traversing block mode by means of the command
"JERK" as this would require parameter p2575 ("Activate jerk limitation") to be set to zero.
The status signal r2684.6 ("Jerk limitation active") indicates whether or not jerk limitation is
active.
