Parameterization; Programming - Siemens SINUMERIK 840D sl Function Manual

B2: Acceleration
5.2 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
5.2.5.2

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)
5.2.5.3
