1)Is newly initiated means: For absolute encoders, the absolute value is newly read out, and for incremental encoders, a restart will take place as after POWER ON.

2)For incremental encoders, r2684.11 ("Reference point set") is reset, and for

absolute encoders, also the status of the adjustment (p2507).

3)For incremental encoders, r2684.11 ("Reference point set") is reset, and for absolute encoders, the adjustment status (p2507) is not reset because the EDS differs from the original one.

7.9.4Traversing blocks

Description

Up to 64 different traversing tasks can be saved. The maximum number is set using parameter p2615 (maximum number of traversing tasks). All parameters which describe a traversing order are effective during a block change, i.e. if:

●The appropriate traversing 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.
