The maximum angular or linear axis acceleration must be entered dependent upon machine
data MD30300 $MA_IS_ROT_AX.
In the case of linear interpolation of the axes in a grouping, the grouping is limited
in such a way that no axis is overloaded. With regard to contour accuracy, the control
dynamic behavior has to be taken into account.
Not relevant for error states that lead to quick stop.
Each field element corresponds to a G code in the 59th G code group.

32400 AX_JERK_ENABLE
- Axial jerk limitation
CTEQ
- -
Description:
Enables the function of an axial jerk limitation.
The limitation is set via a time constant; it is always active.
The limitation works independently of the limitations "path-related maximum jerk",
"knee-shaped acceleration characteristic" and the axial jerk limitation of the axes
that are operated in JOG mode or positioning axis mode.

MD32410 $MA_AX_JERK_TIME (time constant for axial jerk limitation)
32402 AX_JERK_MODE
- Filter type for axial jerk limitation
CTEQ
- -
Description:
Filter type for axial jerk limitation:
1:
2:
3:
Type 2 requires more computing time, but causes smaller contour errors for the same
smoothing effect, or smoother movements at the same accuracy.
Type 2 is recommended; type 1 is set as a default value for reasons of compatibility.
The maximum jerk is set in the time constant MD32410 $MA_AX_JERK_TIME.
Recommended values for type 1:
Min. 0.03 s; max. 0.06s.
Recommended values for type 2:
Min. 1 position-control cycle; max. 16 position-control cycles
At a position-control cycle of 2ms, this corresponds to 0.002 to 0.032 seconds.
Type 3 requires the setting of
MD32410 $MA_AX_JERK_TIME
To parameterize a simple bandstop filter, we recommend setting MD32410
$MA_AX_JERK_TIME=0,
However, MD32410 $MA_AX_JERK_TIME > 0 is used to set a specific denominator frequency,
which makes it possible to implement a bandstop filter with amplitude increase for
frequencies beyond the blocking frequency.
MD32402 $MA_AX_JERK_MODE is only active if MD32400 $MA_AX_JERK_ENABLE has been set to
1.
