0 0 EDS0 EDS1 EDS2 encoder_1 xxx enabled ---
1 0 EDS0 EDS1 EDS2 encoder_1 xxx enabled Switching during pulse
inhibit or operation has
no effect
2 0 EDS0 EDS1 EDS2 encoder_1 yyy disabled Pulse inhibit/operation:
Encoder adjustment and
referencing bit
2)
are
reset.
Position tracking is no
longer calculated; it is
not reset until there is a
new encoder
adjustment.
3 0 EDS0 EDS1 EDS2 encoder_2 xxx enabled
4 0 EDS0 EDS3 EDS2 encoder_2 xxx enabled
5 1 EDS4 EDS1 EDS2 encoder_1 xxx enabled
6 2 EDS5 EDS6 EDS7 encoder_1 zzz enabled
Pulse inhibit/operation:
Position tracking is
continued and
referencing bit
2)
is reset.
7 3 EDS0 EDS1 EDS2 encoder_1 xxx enabled MDS changeover alone
during pulse inhibit or
operation has no effect.
8 0 EDS0 EDS1 EDS2 encoder_1 xxx disabled Pulse inhibit/operation:
Position tracking for
EDS0 (of the DDS0)
newly set
1)
and
reference bit
3)
is reset.

relevant
Pulse inhibit/operation:
Position tracking for
EDS (of the DDS0)
newly set
1)
and
reference bit
3)
is reset.
1)
Is newly initiated means: For absolute encoders, the absolute value is newly read out.
2)
For absolute encoders, r2684.11 ("Reference point set") is reset, and also the status of the
adjustment (p2507).
3)
For absolute encoders, r2684.11 ("Reference point set") is reset and the adjustment status
(p2507) is not additionally reset because the EDS differs from the original one.
