2.1 Acceleration without jerk limitation (BRISK/BRISKA) (channel-/axis-
specific)
2.1.1 Detailed Description
2.1.1.1 General Information
General Information
In the case of acceleration without jerk limitation (jerk = infinite) the maximum value is
applied for acceleration immediately. As regards acceleration with jerk limitation, it differs in
the following respects:
• Advantages
Shorter processing times with the same maximum values for velocity and acceleration.
• Disadvantages
Increased load on the machine's mechanical components and risk of inducing high-
frequency and difficult-to-control mechanical vibrations.
