Load gear
Activated -
Activated Changeover during pulse
inhibit or operation has no
effect
Deactivate Encoder adjustment and
d referencing bit are reset.
Position tracking for EDS0
is no longer calculated
and must be re-adjusted
when switching back to
DDS0.
Activated Position tracking for EDS0
is continued and the
referencing bit is reset.
Activated Pulse inhibit/operation:
Position tracking for EDS0
is continued and the
referencing bit is reset.
Activated Position tracking for EDS4
is newly initiated and the
referencing bit is reset.
When switching back to
DDS0, the same applies
to EDS0.
Activated Position tracking for EDS5
is newly initiated and the
referencing bit is reset.
When switching back to
DDS0, the same applies
for EDS0.
Activated MDS changeover alone
during pulse inhibit or
operation has no effect
