Functions
2.1 Acceleration without jerk limitation (BRISK/BRISKA) (channel-/axis-specific)
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.
2.1.3.2 Single-axis acceleration without jerk limitation (BRISKA)
Syntax
BRISKA (
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.).

• Value range: Axis identifier for channel axes
Axis-specific initial setting
Acceleration without jerk limitation can be set as the axis-specific initial setting for single-axis
movements:
MD32420 $MA_JOG_AND_POS_JERK_ENABLE = FALSE
Reset response
The axis-specific initial setting is activated via a reset:
MD32420 $MA_JOG_AND_POS_ENABLE
