Maximum axial acceleration for JOG motions
See Section "Acceleration and jerk for JOG motions (Page 388)".
12.2.1.3

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 (
Function
The BRISKA part-program command is used to select the "without jerk limitation" acceleration
profile for single-axis movements (JOG, JOG/INC, positioning axis, reciprocating axis, etc.).
G group: -
