JohnR Posted March 12, 2011 Share Posted March 12, 2011 I am running a motion program to move 2 axes in a coordinate system. I have define the LookAhead to 10000 and setup the move as follow FRAX(X,Y) linear abs F(1) //; ( Engineering Units / sec ) //; move the Axes X(2) Y(-2) //; wait for move to complete Dwell(10) The Coord status does not show the LookAheadActive being true at all. If I delete the LookAhead and run the same program It seems to act the same as with the LookAhead defined. How can I determine if my lookahead is actualy running ? Should the Coord[1].LookAheadActive be true for the entire move ? Thanks Link to comment Share on other sites More sharing options...
Omron Forums Support Posted March 14, 2011 Share Posted March 14, 2011 Did you enable segmentation? To use special lookahead, you must set Coord[x].SegMoveTime > 0. You must also set Coord[x].LHDistance > 0. Please refer to the Power PMAC Saved Data Structure Elements manual for more details. Link to comment Share on other sites More sharing options...

It was my LHDistance was set to 0 Why dosen't the LHDistance show up in the Coordinate System Setup Variables display? John Link to comment Share on other sites More sharing options...
