Loading
a part
program which has
a
pro¬
gram
number.
NOTES
.
Program number "OOOOO"
is
always
in
the
registered
state,
so
it cannot
be erased.
This
program
number should
not
be used.
1.
a.
Select EDIT mode.
b. Depress the PROG
key.
c.
Load the
NC
tape to the tape reader
equivalent external device.
2.
The tape which has
no
program number may
be
stored
as
described before.
However,
write a
program number
to
the
head of
the
tape,
in
principle. The
operation of "Oxxxx
IN"
described
before causes
only
program
number registration.
It
does
not
cause the
storing of
information of "OOOOO"
into the
part
program memory.
Only the program
number
on tape is
stored
into
the memory.
Assume
that
a tape
having
no
program
num¬
ber
is
stored and then all
part
programs
are
punched
out
by
depressing
"0,"
"9,"
"9," "9," "9," and
"OUT"
keys. Since this
tape
contains
programs with
no
program

Then the system starts
to
read the tape and
enlists the

as
the

The system
checks
for
a
duplicat
of the program number as
in

Operation ends with error if the
designated
program number
is
not
found
on
the tape.
When
