detector
When

is

ON.
the
current
tool
position
is
set
to
coordinates
0(0,
0,
0).
In
other
words,
the
current
tool
position
is
temporarily
assumed
to
be
the coordinate
origin
until
the
appropriate
coordinate
system
is
set.
O
In
a
slate
where
G92
(reference
coordinate
system)
is
not
set.
a
work
coordinate
system
is
shifted
from
the
origin
of
the
machine coordinate
system.
O
In
a
state
where
G92
(reference
coordinate
system)
is
set,
a
work
coordinate
system
is
shifted
from
the
origin
of
the
reference
coordinate
system.
Q
If
G92
is
instructed
in
a
stale
where
a
work
coordinate
system
is
set,
the
reference
coordinate
system
is
set
so
that
the
current
tool
position
becomes the coordinate
values
instructed
by
G92,
and
at
the
same
time
the
work
coordinate
system
is
shifted
from
the
origin
of
that
reference
coordinate
system.
@
If
work
coordinate
system
cancel
(G52)
is
instructed,
the
work
coordinate
system
returns
to
the
reference
coordinate
or
machine
coordinate
system.
The
same
applies
when
the local
coordinate
system
is
canceled.
