2.1.3 DECIMAL POINT PROGRAMMING
Numerals containing a decimal point may be used
as the dimensional data of addresses related to
coordinates (distance) , angle, time and speed.
They can be input” from punched tape or MDI.
Decimal points can be used in the following ad-
dress words.
Coodinate words;
X, Z, U, W, I, K, R
Angle words: A, B
Feedrate word: F, E
Time words: U, P
EXAMPLE

X15.0000 in.
220.5000 in.

(for F24)
F25. 60 mm/min

When data without a decimal point is input, the
control regards
11111as o.001 mm (or 0.0001 inch).
2.1.4
LABEL SKIP FUNCTION
In the following cases the label skip function
becomes effective, and LSK is displayed on the
CRT .
. When the power supply is turned on.
. When the RESET operation is executed.
While the label skip function is effective, all data
on the punched tape up to the first EOB code are
neglected.
When LSK is displayed on the CRT in
the MEM (memory) or EDIT (editing) mode, it in-
dicates the presence of a pointer at the leading
end of the part program.
2. 1.5
BUFFER REGISTER
During normal operation, one block of data is
read in advance and compensation is computed
for the follow-on operation.
In the tool radius compensation”- mode, two
blocks of data or up to 4 blocks of data are read
in advance and compensation computing required
for the next operation is executed. One block
can contain up to 128 characters including EOB .
The blocks including the following
M codes
are not read in advance .
. MOO, MO1, M02, M30
. M codes ( 6 maximum) set by parameter com-
manding to stop advance–reading.
Notes :
1. This function is effective for G22 and G 23
where the control is provided with Radius
Programming for Circular Interpolation option.
2.
Block-to-block stop time due to the time
required to compute tool radius compensa-
tion is not eliminated or remains.
To reduce
this stopping time, use 2.7.3
Buffering
Function (M93, M92) (optional).
When opera-
tion of consecutive blocks up to 5 in M93
mode, inter-block stoppage time is reduced
to zero.
2.2 PROGRAM NUMBER AND SEQUENCE
NUMBER
2.2.1 PROGRAM NUMBER
Program numbers may be prefixed to programs
for the purpose of program identification.
Up to 4 digits may be written after an address
character
“O” as program numbers. Up to 99
program numbers can be registered in the con-
trol, and up to 199 or 999 can be registered em-
ploying an option.
One program begins with a program number, and
ends with
M02, M30 or M99. M02 and M30 are
placed at the end of main programs, and M99 is
placed at the end of subprograms.
PROGRAM WITH PROGRAM WITH
PROGRAM NO. 10 PROGRAM No. 1224
ER (or % at 1S0 code) is punched on both end
parts of the tape.
Notes :
1. The blocks for optional block skip such as
/M02; , /M30; ,
/M99; are not regarded as end
of programs.
2.
It & possible with a parameter change
(#6201Do) , to make the reading of M02, M30,
and M99 ineffective as a program end, and
to make the succeeding ER (EIA) or % (ISO)
as a sign of program end.
