specify
the tool

compensa¬
tion
planes
(G41/G42),
in
addition
to
the
circular
interpolation
planes.
Unless
otherwise
specified,
XY
plane
(G17)
is
automatically
selected
when
power
is switched
on.
The
plane
oncircular
interpolation
is determined
automatically
by
the
combination-
of
the address
codes
used
X,
Y
or
Z
(or
0+
)
and
I,
J
or
K.
Where
no
plane
can
be
determined
due
to
the
omission
of
address
codes
or
otherwise,
the
specifications
of
plane
by
means
ofG17,
G18
or
G19
becomes
effective.
In
principle,
when
giving'
circular
interpolation
command
(G02or
G03),
the
interpolation
plane
is
designated
by
G17,
G18
or
G19
in
advance.
