Parameterization; Programming - Siemens SINUMERIK 840D Function Manual

B2: Acceleration and jerk
12.2 Functions
The value specified in the setting data is only taken into account if it is smaller than the path
acceleration calculated during preprocessing.
The limitation must be activated for specific channels using setting data:
SD42502 $SC_IS_SD_MAX_PATH_ACCEL = TRUE
12.2.5.2

Parameterization

Parameterization is carried out for specific channels using setting data:
SD42500 $SC_SD_MAX_PATH_ACCEL (maximum path acceleration)
SD42502 $SC_IS_SD_MAX_PATH_ACCEL (activation of path-acceleration limitation)
12.2.5.3
