Is newly initiated means: For absolute encoders, the absolute value is newly read out, and for
1)
incremental encoders, a restart will take place as after POWER ON.
For incremental encoders, r2684.11 ("Reference point set") is reset, and for
2)
absolute encoders, also the status of the adjustment (p2507).
For incremental encoders, r2684.11 ("Reference point set") is reset, and for
3)
absolute encoders, the adjustment status (p2507) is not reset because the
EDS differs from the original one.

Pulse inhibit: Position
actual value conditioning is
newly initiated and
1)
reference bit is reset.
3)
Operation:
Fault message is
generated. Position actual
value
preprocessing is newly
initiated
1)
and reference bit is
3)
reset.
MDS switching alone
during pulse inhibit or
operation has no effect
