Select the lowest frequency of all rotary axes for the default setting of the
CLP filter (defaultCutterLoc).
2. Set the jerk
While the path jerk (MP_axPathJerk) is determined via the following error
(servo lag) at the transition from acceleration to constant feed rate, you set the
transition jerk (MP_axTransJerk) at the reversal point of the axis.
Step 1: Set the axis-specific path jerk (MP_axPathJerk)
Basic settings:
Set a very high value for the maximum path jerk (so that there is no
limitation):
CfgLaPath: MP_maxPathJerk and MP_maxPathJerkHi
(Hi values apply to rapid traverse in general)
Use the advanced HSC or triangle filter:
MP_shape = AdvancedHSC or
MP_shape = Triangle
Enter the machine frequency in MP_frequency
Deactivate feed-rate smoothing:
MP_filterFeedTime = 0 (software option 2)
Set a very low transition jerk value for the measurement because the path
jerk and transition jerk overlap:
MP_axTransJerk = 1
