Position Changeover
tracking response
Load gear
deactivated Pulse
inhibit/operation:
Referencing bit is
reset. Position
1)
tracking for
EDS0 is no
longer calculated
and, as a
consequence,
the position
actual 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. It only
1)
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
1)
switching back to
DDS0, the same
applies to EDS0.
