<mode>
Maximum axial acceleration for JOG motions
For JOG mode, a JOG-specific maximum acceleration value can be configured for each
machine axis (see Section "Acceleration and jerk for JOG motions (Page 282)").
5.2.1.3

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 (
