B1: Continuous­path Mode, Exact Stop, LookAhead
3.4 Dynamic adaptations
The parameter assignment is changed as follows:
MD20465 $MC_ADAPT_PATH_DYNAMIC[1] = 4
MD20460 $MC_LOOKAH_SMOOTH_FACTOR = 1.0
This results in a path velocity profile with adaptation of the dynamic path response and with minimum, and thus
virtually deactivated, smoothing of the path velocity:
The smoothing factor is set to 0% instead of 1% (in accordance with the default!):
MD20460 $MC_LOOKAH_SMOOTH_FACTOR = 0.0
A smoothing factor of 100% comes into effect with this parameter assignment.
This gives rise to a path velocity profile with smoothing of the path velocity and adaptation of dynamic path
response:
