Acceleration behavior

3.14.2.1

Acceleration mode (BRISK, BRISKA, SOFT, SOFTA, DRIVE, DRIVEA)

The following part program commands are available for programming the current acceleration
mode:
● "BRISK, BRISKA"
The single axes or the path axes traverse with maximum acceleration until the programmed
feedrate is reached (acceleration without jerk limitation).
● "SOFT, SOFTA"
The single axes or the path axes traverse with constant acceleration until the programmed
feedrate is reached (acceleration with jerk limitation).
● "DRIVE, DRIVEA"
The single axes or the path axes traverse with maximum acceleration up to a programmed
velocity limit (MD setting!). The acceleration rate is then reduced (MD setting) until the
programmed feedrate is reached.
