"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
3)
(p2507) is not reset in addition, because the encoder data set is different from the original.

parameter p0494 is dependent on an encoder data set; for example which can be used for
the data set switchover for interchangeable machining heads.
