2.16 Excessive jerk for block transitions without constant curvature (axis-
specific)
2.16.1 Detailed Description
2.16.1.1 General Information
Overview
In the case of block transitions without constant curvature (e.g. straight line > circle), the
programmable controller has to decelerate movement of the geometry axes significantly in
order to ensure compliance with the parameterized axis dynamics. For the purpose of
reducing/avoiding deceleration in connection with block transitions without constant
curvature, a higher level of axis-specific jerk can be enabled.
The excessive jerk is parameterized using a dedicated axis-specific maximum value.
