NOTE
O
The
G53
command
must
always
be
issued
under
the
following
conditions
(otherwise,
alarm
“322"
may
result):
•
Not
in
a
mirror
image
•
Not
in
a
canned
cycle
or
tool
radius
compensation
C
•
The
immediately
preceding
01-group
G
code
is
any
of
GOO.
G01,
or
G60.
•
G53
and
GOO
are
not
instructed
in
the
same
block.
O
If
the
G53
command
is
executed
when
machine
lock
is
ON,
the
current
value
display
moves
until
a
command
value
by
which value
must
otherwise
be
moved
if
machine
lock
is
OFF,
is
reached
before
completion.
If
machine
lock
ON/OFF
is
switched
over
in
the middle
of
the
G53
block,
the
machine
will
not
he
correctly
positioned.
However,
if
one
whole
block
of
G
53
is
executed
in
a
machine
lock
OFF
state,
the
machine
is
correctly
positioned
as
in¬
structed
regardless
of
whether there
was
machine
lock
intervention
previously.
Q
Be
sure
to
use
the
G53
command,
in
the
G90
mode.
If
G53
is instructed
while
still
in
the
G91
mode,
the
coordinate
value is
handled
as
the value
of G90
mode.
®
If
G53
is
instructed
in
a
state
where tool
length
offset
or
tool
position
offset
is
applied.
movement
is
made
with
the
corrected

temporarily
canceled.
It
is
generally
recom¬
mended
to
instruct
G53
after
canceling
the
tool
length
offset
or
tool
