The following table contains a few examples for data set changeover. The initial data set is
always DDS0.

"Is newly initiated" means: For absolute encoders, the absolute value is read out again and for incremental encoders a
restart is performed as after a POWER ON.
For incremental encoders r2684.11 ("Reference point set") is reset, and additionally for absolute encoders the status of
adjustment (p2507).
For incremental encoders r2684.11 ("Reference point set") is reset, and for absolute encoders the status of adjustment
(p2507) is not reset in addition, because the encoder data set is different from the original.
