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

Function
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.
