Operation:
Error message is
generated. Position actual

preprocessing is newly
initiated 1)
and reference bit 3) is
reset.
7 3 EDS0 EDS1 EDS2 encoder_1 xxx disabled MDS switching alone
during pulse disable or
operation has no effect
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.

7.9.4 Traversing 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.
