4.2.2.4 Programming
Path acceleration without jerk limitation (BRISK)
Syntax
BRISK
Functionality
The BRISK part-program instruction is used to select the "without jerk limitation" acceleration profile for the
purpose of path acceleration.
G group: 21
Effective: Modal
Reset response
The channel-specific initial setting is activated via a reset:
MD20150 $MC_GCODE_RESET_VALUES[20]
Supplementary conditions
If the acceleration profile is changed in a part program during machining (BRISK/SOFT) an exact stop is
performed at the end of the block.
Single-axis acceleration without jerk limitation (BRISKA)
Syntax
BRISKA ( axis{,axis} )
Function
The BRISKA part-program instruction is used to select the "without jerk limitation" acceleration profile for single-
axis movements (JOG, JOG/INC, positioning axis, reciprocating axis, etc.).
G group: -
Effective: Modal
