3.4.4 Interaction between the "smoothing of the path velocity" and "adaptation of the path
dynamic response" functions
The following examples serve to illustrate the interaction between the "smoothing of the path velocity" and
"adaptation of the path dynamic response" functions in continuous-path mode.
Example 1
Acceleration mode: BRISK
The path involves the 3 axes X = AX1, Y = AX2, Z = AX3.
The following parameters are assumed:
MD20465 $MC_ADAPT_PATH_DYNAMIC[0] = 3
MD20460 $MC_LOOKAH_SMOOTH_FACTOR = 80.0
MD32440 $MA_LOOKAH_FREQUENCY[AX1] = 20
MD32440 $MA_LOOKAH_FREQUENCY[AX2] = 20
MD32440 $MA_LOOKAH_FREQUENCY[AX3] = 20
