The referencing bit (r2684.11) is reset for a DDS changeover. If, in the new DDS, the EDS already has an adjusted

encoder, then the referencing bit is set again.

Deactivate Pulse inhibit/operation:
d Referencing bit is reset.
Position tracking for EDS0
is no longer calculated
and, as a consequence,
the actual position value
also changes (the offset
correction of the position
tracking is canceled).
When switching back to
DDS0, the position
tracking for EDS0 is newly
initiated and the
referencing bit is reset.
only makes sense to
switch back to DDS0
without a new adjustment
in DDS0 if the user did not
make a new adjustment in
DDS8 and the permissible
tolerance window (p2722)
was not exited.
Activated Pulse inhibit/operation:
Position tracking for EDS6
is newly initiated and the
referencing bit is reset.
When switching back to
DDS0, the same applies
to EDS0.
