2.1.3 DECIMAL POINT PROGRAMMING
Numerals containing a decimal point may be used
as the dimensional data of addresses related to
coordinates (distance) , time and speed.
Decimal points can be used in the following ad-
dress words.
Coordinate words: X, Y, Z, I, J, K, A, B,C,
U, V, W, Q, R
Time word: P
Feed rate word: F
EXAMPLE
[ mm] [ i n c h ]
X15. X15.000 mm or x15.0000 inches
— Y 2 0 . 5 0 0 m m or 5000 inches
– O mm/min or inches/rein
( f o r ( f o r
— Dwell 1.000 sec
Normally, when data without a decimal point is
input, the control regards as O. 001 mm
(or 0.0001 inches, or 0.001 deg.).
2.1.4 LABEL SKIP FUNCTION
In the cases named below, the label skip function
becomes effective , and LSK is displayed on the
C R T .
. When the power supply is turned on.
. When the RESET key is pushed.
While the label skip function is effective, all data
on the punched tape up to the first EOB code are
n e g l e c t e d .
When LSK is displayed on the CRT
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 , block of data is
read in advance and compensation computing is
made for the follow-on operation.
In the tool radius compensation C 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 .
2.1.6 MULTI-ACTIVE REGISTERS t
For the portion of part programs sandwiched in
between M93 and M92, up to blocks of data are
read in advance.
M code
I
Meaning
M 92 Multi-active register off
M93 Multi-active register on
Note: When power is applied or the control is
reset, the control is in the state of M code
marked with
Inter-block stoppage can be eliminated when the
program is so made that the automatic operation
time of advance reading of 4 blocks is longer than
processing time of advance reading of next 4
blocks of data.
Note :
Advance reading is not made for every 4 blocks
but is always ready to be made up to 4 blocks in
M93 mode.
NUMBER AND SEQUENCE
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
program numbers. up to 99
program numbers can be registered in the con-
trol, and up to 199 or 999 can be registered
employing an option.
One program begins with a program number, and
ends with M02,
or M99. and are
placed at the ends of main programs, and M99 is
placed at the ends of subprograms.
PROGRAM WITH PROGRAM WITH
PROGRAM NO. 10 PROGRAM NO. 1234
ER (or at ISO code) is punched on the tape at
the top and end of the program.
Notes :
The blocks for optional block skip such as
, /M30; , are not regarded as ends
of programs .
. To make the reading of M02, M30, and M99 in-
effective as a program end, and to make the
succeeding ER or % (I SO) as a sign of
program ends is possible with a parameter
change. (
