windell747 Posted September 9, 2015 Share Posted September 9, 2015 Hi All, Is there any way to limit the acceleration of an axis that is running currently in PVT mode? thank you, windell Link to comment Share on other sites More sharing options...
bradp Posted September 10, 2015 Share Posted September 10, 2015 With PowerPmac you should be able to activate multiblock lookahead. This is from page 689 of the ppmac usermanual Jan 6 2015. Lookahead with PVT Moves The trajectories from PVT mode moves can be passed through the special lookahead buffer for dynamic limiting, just as those from linear and circle mode moves are, if the coordinate system is in segmentation mode (Coord[x].SegMoveTime > 0). Each segment derived from the commanded PVT mode move is checked for possible violations of position, velocity, and acceleration limits for every motor, and the time for the segment is extended if necessary to avoid exceeding any of these limits. As with linear and circle mode moves, the path generated is not changed, only the speed at which the path is traversed is. Link to comment Share on other sites More sharing options...
