5.5.6 Jerk limitation
Acceleration and deceleration are step–like if jerk limiting is not used.
Using jerk limiting, a ramp–type increase can be parameterized for both
quantities, so that approach and braking are ”smooth” (jerk–limited).
Jerk limiting can be used, e.g. for positioning tasks using liquids or gen-
erally to reduce the mechanical stressing on an axis.
