YASNAC LX3

CNC SYSTEM FOR TURNING APPLICATIONS

Before initialoperation read these instructionsthoroughly,and retain forfuture reference.

YASKAVW

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. are marked with a dagger. For the specifications of your YASNAC LX3, builder’s manual.

The optional features

refer to the machine tool

YASNAC LX3 OPERATOR’S STATION

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. 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.

For operation of your NC machine,

1. INTRODUCTION

YASNAC LX3,

is a combination of two high-performance 16-bit

microprocessors running in parallel.

ing our modern system technique, it is designed

to provide the highest lathe performance.

The dual processor CNC system drastically reduces the data processing time to meet highspeed cutting. creased by the use of high-speed buffer function and buffering function.

. Enhanced cutting capability includes a maximum

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 function, tool life control, user macro, tool set error correction, stored stroke limit per tool, and other functions can be installed.

2. PROGRAMMING

. Part program memory can be extended to a

maximum of 320 meters . 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, G 50–work coordinate system setting, angle–specified line– ar interpolation, and combined beveling/rounding function.

. The servo function uses a drastically miniatur-

ized and low-noise, newly transistorized PWM control unit and a high-performance DC servo motor.

The position feedback is available with the standard pulse generator (PG) system and, the inductosyn-applied complete closed loop system.

2.2.1 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 can be registered in the control, and up to 199 or 999 can be registered employing an option.

One program begins with a program number, and ends with placed at the end of main programs, and M99 is placed at the end of subprograms.

2. 2.2 SEQUENCE NUMBER

2.3 COORDINATE WORDS

Integers consisting of up to 4 digits may be writ-

ten following an address character N as sequence

numbers.

Sequence numbers are reference numbers for

blocks, and do not have any influence on the

meaning and sequence of machining processes.

Therefore, they may be sequential, non-sequen-

tial, and duplicated numbers, also not using

any sequence number is possible. sequential numbers are convenient as sequence numbers.

When searching for sequence numbers, be sure

to search or specify program numbers beforehand.

Notes :

Generally,

1. Five or more digits must not be written as a

sequence number.

When two or more blocks have the same sequence number, only one is retrieved and read, and no more searching is performed.

3. Blocks without sequence numbers can also be searched for with respect to the address data contained in the blocks.

Inch/MM input is selected by setting #6001D0. Inch/MM input selection by G20/G21 is optional. Selection of multiplication factor xl /x10 is made by parameter #6006D 5.

Tool offset value must always be written in O. 001 mm (or O. 0001 inch) , and offset is possible in these units.

In O. 01 mm increment system, the following operation must be made in the unit of O. 01 mm.

. Programming for operation in TAPE mode. o Write operation in MDI mode. o Programming for operation in MEMORY mode. . Program editing operation in EDT mode .

Notes :

If NC tape programmed by O. 001 mm is fed

into or stored in an equipment set by O. 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 tenth of the commanded dimensions.

When the stored program is punched out on the tape+, the stored f?gures are punched out “as stored” regardless of switching of the increment system.

Multiplication factor 10X (10 times the input unit) is effective for distance command only. It does not function on the designation of time, angle”, etc. 10X is set as effective ( #6006D5 = 1) , the same address word is multiplied by 10 or not depending on type of G command.

commands are modal. Although the spindle stops at the M05 command, the S command is retained.

Therefore, when M03

(or M04) is given, the spindle runs accord-

ing to the S command.

(4) When S command is changed after the spin-

dle start by M03 or M04, S command should be given within the range of spindle speed selected by spindle gear.

Notes :

The lower limit of the spindle speed depends on the spindle drive. Refer to the machir,e tool builder’s manual for the low-speed limit. Negative S commands must not be programmed.

When the control is provided with the S 4digit command function, the “Spindle speed override” option can be built into it.

With machine tools with which the main spindle gear ratio changes can be specified by M codes, first write the applicable M code to preselect the desired gear ratio, and then, write the S command.

Refer to the data of

the machine tool builder for the number of

gear ratios, the speeds at various gear ratios,

and other details.

When the control is provided with this func -

As mentioned above, when the tool specified by the address T and 4 digits is moved, the offset value corresponding to the tool offset number is added to the command value in the program algebraically and the tool tip is moved to the offset position.

When there is no move command in the block, the tool moves only by the offset value. Once, the tool offset number is designated, the tool moves always to the offset position until another number is designated. When the other offset number is designated or the offset value is changed, the offset value is compensated for by the amount of the difference between the old and new offset values.

Notes :

When the program No. specified by address

1. P and the sequence No. specified by Q are not found, alarm code 041 is displayed.

While command L for the number of repetitions

2. is under execution, the remaining number of repetitions can be displayed. For details refer to 4.3.2.2.

This function can be used when subroutine

When subroutine programs are nested more

2.7.7 M 3-DIGIT BCD OUTPUT+

When the control is provided with the M 3-digit BCD output option, it can command M 3–digit

codes between MOO and M999.

(1) M codes between MOO and

M11O

and M999 are output in 3-digit BCD

codes.

(2) M90 through M109 are internal processing

M codes, and no BCD code for them is output. See 2. 7.2 PROCESSING .

The specific usages of the M 3-digit codes

(4)

depends on machine tool design. ‘Refer to machine tool builder!s manual.

2.7.8 HIGH-SPEED M FUNCTION

This function is used to execute the M function at

high-speed without the need of the ending

response.

The M code is not output when the M code is

commanded, but the M decode output is setlreset. Thus, there is no need for the M code decode

processing and

controller.

The M code that perform the high-speed M

function processing is preset in the parameter.

(There are both a setting parameter and a

resetting parameter. )

When resetting
