Acceleration pattern: BRISK, SOFT

BRISK
The axes of the machine change their velocities using the maximum permissible acceleration
value until reaching the final velocity. BRISK allows time-optimized working. The set velocity
is reached in a short time. However, jumps are present in the acceleration pattern.
SOFT
The axes of the machine accelerate along a non-linear, constant characteristic until reaching
the final velocity. With this jerk-free acceleration, SOFT allows for reduced machine load.
The same behavior can also be applied to braking procedures.
