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.

Changeover response
---
Changeover during pulse
inhibit or operation has no
effect
Pulse inhibit: Position
actual value conditioning is
newly initiated and
1)
reference bit is reset.
2)
Operation:
Fault is output. Position
actual value conditioning is
newly initiated and
1)
reference bit is reset.
2)
Pulse inhibit: Position
actual value conditioning is
newly initiated and
1)
reference bit is reset.
3)
Operation:
Fault is output. Position
actual value
preprocessing is newly
initiated
1)
and reference bit is
3)
reset.
MDS changeover alone
during pulse inhibit or
operation has no effect
