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.

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. )

Note that if the end point is designated in the

shaded area, the alarm is not displayed and the

tool will continue to move endlessly.

The end point coordinate should be precisely commanded when the circular interpolation is

apphed to the tool nose radius compensation, or the tool may not move properly. Generally, it is recommendable to calculate up to the next

digit of least input increment and count fractions over 1/2 as one and disregard the rest.

HOW to enter compensation mode

(5)

a. Compensation mode is set when both the tool

offset number by T code and G41 (or G42 through G44) are instructed. When this mode is set, tool nose radius compensation is started. More precisely, compensation mode is entered when the AND condition between T code and G code is established. Hence, the order in which these codes are specified does not affect the operation.

c. If the block of G41 (or G42 through G44)

Since G41 (or G42 through G44) involves such a movement, it is necessary to specify GOO or GO1 in th last or current block for the G code of 01 group. Specification of a G code other than GOO, GO1, and Gll will

result in alarm “026. “

end point of the finalblock in compensation mode, or the block immediately before

that for which G40 or T 3700 has been

specified. (Consequently, if a retracting which results in acute–angle contour is specified in G40 or T 3E 00 block, no uncut portion is produced. ) Then, the tool moves so that the virtual tool nose matches the end point of the move command specified in G40 or T all00 block.

The purpose of this feature is to retain a

another macro program. Quadruple nesting is permitted for simple call and modal call combined. Multiple call is disabled for the macro

call by arbitrary G code, or M code or T code.

Multiple Call by G66 Modal Call

modal call, each time a move command is ex-

ecuted, the designated macro is run.

This is also valid for the move command in the macro called by multiple call.

The macros are sequen-

tiallyexecuted from the one designated latest.

b. For both types I and II, addresses I, J, and K should be designated in this order. The other addresses may be designated in any order.

c. In the argument designation part, negative sign and decimal point may be used regardless

of the address.

d. In

G65 and G66 blocks, G65 and G66 should

always be specified before each argument designation.

This holds true with the macro call by

2.8,23.5 Operation Commands

Various operations can be performed between variables and between variables and constants . The operation expression is represented in the form of #i = <expression> , in which < expression> is a general arithmetic operational expression produced by combining variables and constants with operators and functions. The available operations and functions are as follows. Instead of fi and #k, constants may be used.

(1) Variable Definition and Replacement

#i = #j . . . definition, replacement.

(2) Add-Type Operations

#i. #j+#k . . .

#i=#j -#k . . . #i=#j OR#k . . .

Sum. Difference. Logical sum (for each of

32 bits) .

#i=#j XOR #k...

Exclusive logical sum

(for each of 32 bits).

(3) Multiply-Type

#i=#j *#k . . .

#i=#j /#k . . . #i=#j AND #k...

Operations

Product.

Quotient.

(f& each of 32 bits) .

Note: In OR, XOR , or AND operation, the variable value (or constant) is converted into the binary 32–bit equivalent and the operation is performed on each bit.

(4) Functions

(6) Change of Operational Order by [ ]

Priority may be given to an operation by enclosing it in brackets [ ] . Up to quintuple (five-

hold) nesting of brackets is permitted including those of functional operations.

Sample

(7) Considerations for Operational Commands

a. The constant without decimal point used in

<expression > is assumed to have a decimal point

at its end.

When used in conditional Expression IF or

WHILE, function ROUND truncates the fractions.

c. When used in address data, function ROUND

rounds off the part below the least significant digit.

Sample (a)

12.3758

#10 =

When the least significant digit of address

X is O. 001 mm, the following command

Goo x [ROUND [ #lo]];

means GOO x12.376 ;

because 8 of 12.3758 is rounded.

This command is also equivalent to

] h]

This is because the data of #10 and #11 in @ and @ blocks are substantially rounded before being executed.

If @ block is

@ GOO U- [#10 +#11] ;

then, the movement is made by the following

amount:

U- [#10 + #H] = U - [12.3758 + 13.1236]

= U - [25.49@ —

- U - [25. 499]

On the other hand, block movement of

~+@is

rJ#10 + U#ll = U12. 376 + U13. 124

Hence, the program of @ is not correct.

(8) Operational Errors

The data format and the operational errors in the macro programs are as follows:

a. Data Format

The numeric data handled in macro programs are of the floating point format.

= U25. 500

where, M is sign + data 52–bit binary,

E is sign + data 10-bit binary.

b. Operational Errors

Each time an operation is performed, the following error is caused and is accumulated. The number of significant digits is 15 to 16, which compensates the error sufficiently.

2.8,23.6 Control Commands The commands which control the flow of the

micro–program are of the following two types:

a. Branch command . . . ssion>] GO TO n ;

b. Repeat Command . . . WHILE [ < conditional

expression > ] DO m ,

(1) Branch Command

a. IF [ < conditional expression >] GO TO n ;

If < conditional expression>of this command is established, a branch is made to the block of sequence number n within the same program. When a variable or an expression is used for n, the branch destination may be changed. If the condition is not satisfied, the program proceeds to the next block.

IF [ f conditional expre-

Conditional expressions are EQ , NE, CT, LT, GE, and LE. They are represented as follows:

A variable and <expression > may be

#i EQ#j (#i= ?#j) #i NE#j #i GTi!j #i LT#j (#i < #j) #i GE#j #i LE#j (#i Z #j)

and < expression> may be used for #i

Meaning

Notes:

The sequence number must be located at the head of the block when it is called for by a branch command. the sequence number is ignored as shown below:

(2) Difference between Macro Program and Sub-

program.

a. User macros G65 and G66 allow argument

designation but the subprogram (M98) does not.

The macro program directly branches to the

macro program body without executing any command that was specified in G65 or G66 block and has no relationship with the macro. With the

subprogram, however, a branch is performed after the execution of the command (ifany) other than P and L in M98 block.

The maximum nesting level of macro program

c. is quadruple including G65 and G66 calls, of subprograms is also quadruple but separately.

If macro programs are specified via MDI

d. during automatic operation, the maximum nesting level is restricted to quadruple. With subprograms,

in tape mode or memory mode, or separately in

MDI mode,

up to four levelS of nesting are permitted

(7) Parameter Setting of Program Number

Classification

(3) Relationship with MDI Operation

a. MDI writing permits the macro call and the

execution of the called macro,

b. MDI writing does not permit or execute macro body commands such as operational commands and

control commands.

When a macro program being executed is

stopped by the single block stop function, any MDI writing command not related to the macro may be specified and executed.

(4) Relationship with Address Search

The address search function is not permitted to search for the sequence numbers in the macro

body.

(5) Relationship with Single Block Switch

a. The operational command and control command blocks do not single–block stop if the single block switch is turned on. is enabled for the other macro program blocks.

b. However, when setting number #6004D1 = 1, the single block switch is enabled for the opera–

2.8.24 PROGRAM MIRROR IMAGE (G 68, G 69~

Program

mirror image is the feature to reverse the NC program operation in all directions around the work center line (Z-axis) by the use

of G command.

(1)

G68; . . .

Program mirror image on. The program mirror image on state is held until G 69 is speci–

fied.

G69; “-”

Program mirror image off. The program mirror image off state is held until G68 is speci– fied.

When program mirror image is on, the X-

axis operation by the NC program IS in-

verted with Z-axis being the center line.

The manual operations (manual continuous feed and handle /step feed) are not affected by this feature.

(2)

Details of program mirror image

When the PROGRAM mirror image feature is on, the movement by the NC program is

inverted with Z-axis ‘being the center line. The following inversion is processed in the NC unit:
