2.15.2 Activation
2.15.2.1 Parameterization
Key statement
The maximum value for axis-specific jerk with programmed rapid traverse is parameterized
(G00) using the axis-specific machine data:
MD32434 $MA_G00_ACCEL_FACTOR
(scaling of the acceleration limitation with G00)
This is used to generate the maximum value for axis-specific jerk with programmed rapid
traverse (G00) that is taken into account by the path planning component during
preprocessing:
Jerk[axis] =
MD32431 $MA_MAX_AX_JERK * MD32435 $MA_G00_JERK_FACTOR
2.15.3 Programming
Key statement
The function is not programmable.
2.16 2.16 Excessive jerk for block transitions without constant curvature (axis-
specific)
2.16.1 Detailed description
2.16.1.1 General information
Key statement
In the case of block transitions without constant curvature (e.g., straight > circle), the
programmable controller may have to decelerate 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.
