Look-ahead velocity control
In the continuous-path control mode with G64, the control system automatically determines
the velocity control for several NC block in advance. This enables acceleration and decelera-
tion across multiple blocks with approximately tangential transitions. For paths that consist of
short travels in the NC blocks, higher velocities can be achieved than without look ahead.

8.3.12 Acceleration behavior: BRISK, SOFT
BRISK
The axes of the machine change their velocities using the maximum permissible accelera-
tion value until reaching the final velocity. BRISK allows time-optimized working. The set ve-
locity is reached in a short time. However, jumps are present in the acceleration pattern.
