For every number degree of freedom the user has to delimit its region by UpStreamand DownStreamlocations.
DownStream sets points that define the upper boundary of the moving frame tracking as array of points (in robot units) . Each the array’s element is a limit definition of given degree of freedom (array index). The size of the array is the moving frame’s number of degrees of freedom. DownStream is the upper boundary of the region. The upstream and downstream units are from the moving frame system units (both are from the same units).
The up/down stream limits are used for scaling position in the robot coordinate system. Those values are absolute in the robot word.
< Moving Frame >.DownStream[ ] = <position value>
Versions 4.0.26 and higher
Array of Locations
Array size is according to NDOF
According to the moving frame type
Task or Terminal
The number of points must be as the number of independent axes in the moving frame. Must be set before linking.
Common shared A as location of XYZR
Common shared B as location of XYZR
Common shared C as location of XYZR
CNV.ndof = 3
CNV.DownStream = B
CNV.DownStream = C
