NUMBER
The least
input
increment is
the
minimum
unit
that
can
be
programmed
and
is
represented
in
millimeters
(
or
in
inchest
or
degreest).
2.2.1
4-DIGIT
SEQUENCE
NUMBER
Sequence
number
is
a
reference
number
for
the
block
and
does
not
affect
the
machining
operation
and
order.
Therefore,
sequential
numbers,
dis¬
continuous
numbers,
same
numbers
and
no
num¬
ber
are
acceptable.
But
it
is
recommendable
to
use
numbers
in
numerical
order.
Sequence
number
is
represented
by
four
digits
from
0001
to
9999
with
the
preceding
N.
The
leading
zeros
can
be
suppressed.

NOTE:
When
a
number
of
5
digits
or
over
is
given
as
a
sequence
number,
the latter
4
digits
are
effective.
When
the
same
sequence
number
used
for
several
blocks
is
searched,
address
search
stops
after
reading
out
the
block
found
first.
The
block
without
a
sequence
number
can
be
found
by
searching
the
address
data
in
the
block.

2.3.1
LEAST
OUTPUT
INCREMENT
The least
output
increment
is
the minimum
unit
of
movement
by
which
the
machine
can move
and
is
represented
in
millimeters
per
pulse
(or
in
deg/pulse
).
NOTES:
•
If
NC
tape
programmed
by
0.001
mm
is
fed
in¬
to
or
stored
in
an
equipment
set
by
0.
01
mm
increment,
the
machine
will
move
ten
times
the
intended
dimensions.
•
If
the increment
system
is
switched when
the
contents
of
NC
tape
are
stored
in
memory
+,
the machine
will
move
by
ten
times
or
one
ten¬
th
of
the
commanded
dimensions.
•
When
the
stored
program
is
punched
out
on
the
tape+,
the stored
figures
are
punched
out
"as
stored"
regardless
of
switching
of
the incre¬
ment
system
.
