Acceleration control and exact stop/continuous path
8.7.1
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.
See the following illustration for basic course of the path velocity when using BRISK/SOFT:
Programming
BRISK
; Jerking path acceleration
SOFT
; Jerk-limited path acceleration
Programming example
N10 SOFT G1 X30 Z84 F650
; Jerk-limited path acceleration
N90 BRISK X87 Z104
; Continuing with jerking path acceleration
8.7.2
Exact stop/continuous-path control mode: G9, G60, G64
Functionality
G functions are provided for optimum adaptation to different requirements to set the traversing behavior at the block
boundaries and for block advancing. Example: For example, you would like to quickly position with the axes or you would
like to machine path contours over multiple blocks.
Programming
G60
; Exact stop modally effective
G64
; Continuous-path mode
G9
; Exact stop non-modally effective
G601
; Exact stop window fine
G602
; Exact stop window coarse
