LIST
OF
6
CODES
AND
GROUPS
of
G
codes.
An
"initial

which
the
control
assumes
at
the time
it
is
switched

The
preparatory
functions
are
programmed
with
the address
G
and
two
digits.
Table
2.14.1.3
shows
the list
of
G
codes.
There
are
nine
groups

Notes:

G90
is the
initial
state
when the
parameter
No.
78
is
"0."
When
it
is
"I,"
the
initial
state
is
G91.
2.
GOO
is the initial
state
when the
parameter
No.
09
is
"0."
When
it
is
"l,
"
no
change
occurs.
When
a
reset
is
made
during
a
tool
radius
com¬
pensation
(G41,
G42)
or
canned
cycle
execution,
the
G40
or
G80
state
is
assumed.
In
normal
command
data
display,
only
one
of
G
codes
in
the
A
or
D
group,
and
a
part
of
the
delta
(A)
group
are
displayed.
When
NUMBER
is
set to
99,
all
G
code
groups
can
be
displayed.
(Refer
to
4.3.
1
Display
of
Command
Data.
)
In
the
EDT
mode,
all
G
codes
given
in
the
block
are
displayed,
regardless
of
the
NUMBER
setting.
G43,
G44
and
G49
codes
in
the
AA
group
and
G45
through
G48
in
the
A
group
can
be
given
together
with
the
following
G
codes
in
the
A
group,
within
the
same
block.
G
codes
in
groups
A
through
G
are
modal.
When
a
modal
G
code is
once
programmed,
it
remains
effective
until
another
G
code
in
the
same
group
is
given.
G
codes
in
the
delta
group
(A)
are
non-
modal.
They
are
effective
only
in
the block
containing
them.
G
codes
in
the
double
delta
group
{AA
)
are
modal
only
for
each
specified
axis.
Two
or more
G
codes
in
groups
A
through
G
can
be
programmed
in
one
block.
However,
when
two
or more
G
codes
of
the
same
group
are
pro¬
grammed
in
one
block,
the
last
given
G
code
has
priority.
G
codes
in
the
delta
group
cannot
be
program¬
med
in
combination
with
other
G
codes
in
one
block.
They
must
be
programmed
in
an
sepa¬
rate
block.
(Exceptions
to
this
rule
are
shown
in
Table
2.
14.
1.2.)
When
an
A
-group
G
code
is
given
in
canned
cy¬
cle mode
(G73,
G76,
G81
through
G89),
the
can¬
ned
cycle
is
cancelled,
and
the
D
group
code
becomes
G80.
