2.10.2 Activation
2.10.2.1 Parameterization
Key statement
The proportion of maximum available axis acceleration to be taken into account as an
acceleration margin for radial acceleration on curved contours is parameterized using the
channel-specific machine data:
MD20602 $MC_CURV_EFFECT_ON_PATH_ACCEL
(influence of path curvature on dynamic path response)
2.10.3 Programming
Key statement
The function is not programmable.
2.11 Jerk limitation with path interpolation (SOFT) (channel-specific)

2.11.1 Detailed description
2.11.1.1 General information
Key statement
As far as the functionality described in the rest of this document is concerned, constant
acceleration, i.e., acceleration with jerk limitation (jerk = infinite value), is the assumed
acceleration profile. In the case of acceleration with jerk limitation, linear interpolation is
applied in respect of acceleration from 0 to the maximum value.
Advantages
Minimal load on the machine's mechanical components and low risk of high-frequency and
difficult-to-control mechanical vibrations thanks to constant excessive acceleration.
