The problem is that at the join of conveyors moving at different speeds, the loop stops to pick up the dog interval of the next conveyor.<BR />I've created a simple model representing this problem. How can I prevent the loop from stopping?<BR />The simple model is attached.<BR />Thanks in advance.<BR />Regards.</P> Tue, 10 Mar 2026 07:30:00 GMT https://forums.autodesk.com/t5/flexsim-forum/stopped-in-power-and-free-due-to-change-of-dog-interval-and/m-p/14048785#M100329 rocio_alvarez9R3F7 2026-03-10T07:30:00Z https://forums.autodesk.com/t5/flexsim-forum/stopped-in-power-and-free-due-to-change-of-dog-interval-and/m-p/14048932#M100334 <P>Each conveyor simulates its own dogs.
