2.13 Path-jerk limitation (channel-specific)
2.13.1 Detailed Description
2.13.1.1 General Information
Overview
To enable a flexible response to the machining situations concerned, setting data can be
used to limit the path jerk calculated during preprocessing for specific channels:
SD42510 $SC_SD_MAX_PATH_JERK (maximum path jerk)
The value specified in the setting data is only taken into account in the channel if it is smaller
than the path jerk calculated during preprocessing.
The limitation must be activated for specific channels using setting data:
SD42512 $SC_IS_SD_MAX_PATH_JERK = TRUE
2.13.2 Activation
2.13.2.1 Parameterization
Function
Parameterization is carried out for specific channels using setting data:
SD42510 $SC_SD_MAX_PATH_JERK (maximum path jerk)
SD42512 $SC_IS_SD_MAX_PATH_JERK
(activation of path-jerk limitation)
