Extended FunctionsFunction module “basic positioner”4.24.4 Traversing blocksDescriptionUp to 64 different traversing tasks can be saved. The maximum number is setusing parameter p2615 (maximum number of traversing tasks).All of the parameters that describe a traversing task are effective when a block ischanged, i.e. if:The appropriate block number is selected using binector inputs p2625 to p2630(block selection, bits 0...5) and started using the signal at binector input p2531(activate traversing task).A block change is made in a sequence of traversing tasks.Traversing blocks are parameterized using parameter sets that have a fixedstructure:Block number (p2616[0...63])Every traversing block must be assigned a task number (in STARTER “No.”).The traversing blocks are executed in the sequence of the block numbers.Numbers with task number –1 are ignored, in order to e.g. reserve space foradditional traversing blocks at a later stage.Task (p2621[0...63])1: POSITIONING3: ENDLESS_POS4: ENDLESS_NEG5: WAIT6: GOTO7: SET_O8: RESET_OMotion parameters– Target position or traversing distance (p2617[0...63])– Velocity (p2618[0...63])– Acceleration override (p2619[0...63])– Deceleration override (p2620[0...63])Task mode (p2623[0...63])The execution of a traversing task can be influenced by parameter p2623 (taskmode).
