1. INTRODUCTION

YASNAC J50L,“UltraspeeddualprocessorCNC” isa combinationoftwo high-performance16-bitmicroprocessors runningin parallel.Incorporatingour modern system technique,itisdesignedtoprovidethehighestlatheperformance.

The dual processor CNC system drasticallyreduces the data processing time to meet highspeed cutting. creased by the use of high–speed buffer func– tionand buffering function.

Enhanced cutting capabilityincludes a maximum of 24 meters/reinfeed command, precise feed E

command, 500-milimet-erlead thread cutting, continuous thread cutting, multiplethread cutting, and variable pitch thread cutting.

To meet FMS trends, program interruptfunction,toollifecontrol,user macro, toolset error correction, stored stroke limitper tool, and other functionscan be installed.

2. PROGRAMMING

Part program memory can be extended to a maximum of 320 meters. Its data input/output interfaceis availablewith FACIT, RS232C and, in addition,RS422 serialinterfacecapable of high-speed long distancetransmission.

Programming is further facilitatedby improved toolradius compensation function,G 50–work coordinatesystem setting,angle-specifiedlinear interpolation,and combined beveling/round– ing function.

The servo functionuses a drasticallyminiaturized and low–noise, newly transistorizedPWM controlunit and a high–performance DC servo motor.

The positionfeedback is availablewith the

standard pulse generator (PG ) system and,

the inductosyn-appliedcomplete closed lcQp system.

1. This function is effectivefor G 22 and G 23 where the control is provided with Radius Programming for CircularInterpolationoption.

Block-to-block stop time due to the time required to compute toolradius compensa– tionis not eliminatedor remains.

To reduce this stopping time, use 2.7.3 Buffering Function (h193,M92) (optional). When operation of consecutiveblocks up to 5 in M93 mode, inter–blockstoppage time is reduced to zero.

PROGRAM NUMBER AND SEQUENCE

NUMBER

2.2.1PROGRAM NUMBER Program numbers may be prefixed to programs

for the purpose of program identification. Up to 4 digitsmay be written afteran address

character “O“ as program numbers. program numbers can be registeredin the control,and up to 199 or 999 can be registered employing 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.

up to 99

In the followingcases the labelskip function

becomes effective,and LSK is displayed on the CRT .

. When the power supply is turned on. . When the RESET operationis executed.

While the labelskip functionis effective,alldata on the punched tape up to the firstEOB code are neglected.

When LSK is displayed on the CRT in the MEM (memory) or EDIT (editing)mode, itindicatesthe presence of a pointer at the leading end of the part program.

BUFFER REGISTER

2.1.5 During normal operation, one block of data is

read in advance and compensation is computed for the follow-on operation.

In the toolradius compensation”tmode, two blocks of data or up to 4 blocks of data are read in advance and compensation computing required

for the next operationis executed. One block

can contain up to 128 characters including EOB .

The blocks including the followingM codes are not read in advance .

. MOO, MO1, M02, M30 . M codes (6 maximum) set by parameter com-

manding to stop advance-reading.

PROGRAM WITH PROGRAM NO. 10 PROGRAM NO.

ER (or % at 1S0 code) is punched on both end parts of the tape.

Notes:

1. The blocks for optionalblock skip such as /M02;, /M30;, /M99; are not regarded as end

of programs.

2. It is possiblewith a parameter change (#6201Do), to make the reading of M02, M30, and M99 ineffectiveas a program end, and

to make the succeeding ER (EIA) or % (ISO)

as a sign of program end.

SEQUENCE NUMBER

2.2.2

Integers consistingof up to 4 digitsmay be written followingan address character N as sequence numbers.

Sequence numbers are reference numbers for blocks, and do not have any influenceon 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.

Generally, sequentialnumbers are convenient as sequence numbers.

When searching for sequence numbers, be sure to search or specifyprogram numbers beforehand.

Notes:

1. Five or more digitsmust not be written as a sequence number.

When two or more blocks have the same se– quence number, only one is retrievedand 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.

2.2.3.

OPTIONAL BLOCK SKIP (/1-/9j+)

Those blocks in which “/n” (n = (1 - 9) is included are neglected between In and the end of that block, when the externaloptionalblock skip switch for that number “n” is on.

thisfunctionis ineffective.

3. The block skip /2 - /9 is an option function, and /1 is a basic one.

COORDINATE WORDS

2.3

Generally,

commands for movements in axis direc– tions and commands for settingcoordinatesystems are calledcoordinatewords, and coordinate words consistof address characters for desired axes and numerals representing dimensions of directions.

2.3.2 SIMULTANEOUS CONTROLLABLE AXES

dependent on the machine specificationand are

determined by the machine toolbuilders.

The

rapid traverse rates determined by the machine are set by parameters in advance for-individual axes.

The upper limitfor X-axis speed is halfthe listedvalues. The optimum value of upper limitis set according to the machine. Refer to the machine toolbuilder’smanual,

When a move command and an S code are issued

in a block, execution willdepend on the machine

tooldesign and construction (Whether the S command is executed together with the move com-

mand or afterthe completionof toolmovement) .

Refer to the machine toolbuilder’smanual.

Once specified,S-code is modal and effective

untilthe next S-code.

When the spindlestops at M05 (spindlestop), S-command is stored in memory of the unit.

The area in which toolpositionoffsetvalues, tool radius compensation values, and other comPensa– tiondata are stored is calledOffset Memory.

(3) Write these data in the memory, before start-

ing to operate the machine under automatic control. For the writing procedure, refer to 4.3.5,“Displaying and WritingTool Offset Values.“

For writingintoTool Coordinate

Memory, followthe procedure described in

6.2.3,“Work Measurement Value DirectInputt.“

TOOL POSITION OFFSETS

2.6.3

When the tooloffsetnumber is specified,the off-

set value corresponding to the tooloffsetnumber is added algebraicallyto the command value in the program and the toolis moved to the offset position. Therefore, the differencebetween the coordinatevalues of the programmed tooltipand the actualtooltip must be stored intotooloffset memory in advance as the offsetvalue.

When the coordinatevalue of the actualtooltip

has changed due to toolwear or some other rea-

sons, the toolpositionoffsetvalues should be

set again.

Thus, the programmed machining is

attainedwithout correctingthe program.

Tool positionoffsetis executed by designating the tooloffsetnumber corresponding to the actual toolmust be designated.

Tool offsetstartsat the block in which the T-code is commanded. When T-code is read, the tool selectionsignal (BCD ) is fed and the toolstartsto move by the offsetvalue corresponding to the tooloffsetnumber. Since T code is modal, itis retaineduntil the other T code is designated.

EXAMPLE

This function is used to execute the M functionat 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 set/reset.

Thus, there is no need for the M code decode processing and FIN processing in the programmable controller.

The M code that perform the high-speed M

functionprocessing is preset in the parameter.

(There are both a settingparameter and a resettingparameter.)

When resettingby the parameter, it can be

set to hold or reset the decoding output.
