This manual is primarily intended with 9” CRT
character display (basic) to give operators in–
structions for YASNAC LX3 programming, and
operation.
This manual applies to the basic and optional
features of YASNAC LX3. The optional features
are marked with adagger. For the specifications
of your YASNAC LX3, refer to the machine tool
builder’s manual.

PREFACE
When reading this manual keep in mind that the
information contained herein does not cover every
possible contingency which might be met during
the operation. Any operation not described in
this manual should not be attempted with the
control,
The functions and performance as NC machine are
determined by a combination of machine and the
NC control. For operation of your NC machine,
the machine tool builder’s manual shall take prl–
ority over this manual.
The illustration of machine control station should
be used for your reference in understanding the
function. For detailed array of operator’s devices
and names, refer to machine tool builder’s
manual.
TJnless otherwise specified,
apply to the description of

1. INTRODUCTION
YASNAC LX3, IIultraspeed dual processor CNC”
is acombination of two high-performance 16-bit
microprocessors running in parallel. Incorporat-
ing our modern system technique, it is designed
to provide the highest lathe performance.
The dual processor CNC system drastically re-
duces the data processing time to meet high-
speed cutting. Block-to-block stop time de-
creased by the use of high-speed buffer func-
tion and buffering function.
.Enhanced cutting capability includes amaximum
of 24 meters /rein feed command, precise feed E
command, 500-milimeter lead thread cutting,
continuous thread cutting, multiple thread
cutting, and variable pitch thread cutting.
To meet FMS trends, program interrupt func-
tion, tool life control, user macro, tool set
error correction, stored stroke limit per tool,
and other functions can be installed.
.Part program memory can be extended to a
maximum of 320 meters .Its data input loutput
interface is available with FACIT, RS232C and,
in addition, RS422 serial interface capable of
high-speed long distance transmission.
.Programming is further facilitated by improved
tool radius compensation function, G50–work
coordinate system setting, angle–specified line–
ar interpolation, and combined beveling/round-
ing function.
.The servo function uses adrastically miniatur-
ized and low-noise, newly transistorized PWM
control unit and ahigh-performance DC servo
motor.
The position feedback is available with the
standard pulse generator (PG) system and,
the inductosyn-applied complete closed loop
system.

2.1 TAPE FORMAT
2. 1.1 TAPE FORMAT
Avariable block format conforming to JIS# B
6313 is used for YASNAC LX3.
Table 2.1 shows the tape format. Numerals
following the address characters in Table 2.1
indicate the programmable number of digits.

Note: The decimal point may be omitted in
actual programming. For making aprogram
including decimal points, refer to 2. 1.3
Decimal Point Programming.
The leading zeros can be suppressed for all ad-
dress codes. Plus signs need not be program-
med, but all minus signs must be programmed.
In the manual, EOB code in aprogram example
is represented by a semicolon (;) .In actual
programming, CR (EIA code) or LF /NL (1S0
code )should be used instead of the semicolon
(;).
