Yaskawa has made every effort to de scribe individual func ti ons a nd their relationships to oth er fun ct ions
as accurate ly a s possible. However, there are many things that cannot or must not be performed and it is
not possible to describe al l of th ese . Accordingly, readers are requested to understand that un le ss it is
specifically stat ed that something can be pe rformed, it should be assumed that it cannot be perfor med.

Also, bear in mind that the performanc e a nd functions of an PCNC m a chine tool are not de te rm ined
solely by the PCNC unit. The entire contr ol system consists of the mechanical system, then machine
operatio n pa nel and other machine related equ ip ment in addition to the PCNC. Therefore, read the
manuals publ ished by the machine tool builder for detailed information rela ti ng t o the ma chine.

1.2 Protective Functions

1.2.1 Emergency Stop

Press the emergency stop button immediately if a problem occurs with the system or line. The
execution of all c om m ands stops instantaneously when the emergency stop button is pressed.
Servo power supply of the PCNC is shut OFF and dynamic br ake is applied to stop all
mechanical movement. In the emergency stop state, the PCNC is in the alarm stat e “3002”. If the
emergency stop signal is “opened”, the PCNC stops the en tire operation, and the SVMX and
BKX signals are “opened”.

PCNC

This operation is executed by setting the pins on the board. The pins differ between J300M
and J100M.

1.2.2 Overtravel

The overtravel function stops axis feed operation when an axis reaches the travel limit; for the
detection of travel limit, a limit switch and a dog are used and if an axis reaches the travel limit,
the limit switch outputs a signal a nd th e function stops axis feed operati on i n response to this
input. The axis rea ched and stopped at the tr avel limit can be moved manually into the axis mov­able range.

When the overtravel input is “opened”, axis movement is stopped in the manner as indicated in
Table 1.3. In response to thi s inpu t, the alarm output (ALM) i s “closed” and the corresponding
alarm message is di sp la ye d on the screen.

If the overtravel inpu t is “opened”, select the manual mode (jog, pulse handle) and move the axis
in the direction opposite to the direction for which the overtravel input is “opened” to “close” the
input. After that press the [RESET] key on the NC operation panel, the alarm output and display
are canceled.

YASNAC PCNC Operating Manual Chapter 1: Outline of YA SNAC System

1. After the oc currence of an ala r m d ue to the “open” of the overtravel input, the M, S, and
T code read output signa ls (MF, SF and TF) are not turned OFF.

2. If it is necessary to in te rrupt the operatio n ca ll ed by M, S and/or T code, set th e i nte rl ock
by an external seque nce.

3. The alarm numbers at the occur rence of overtravel are 2001 to 2005. If the overtra v e l
alarm occurs, axis move is stopped. Note that the servo is not turned OFF.

1.2.3 Stored Stroke Limit

To ensure improved safety in operation, this function prevents axis from entering the preset entry
prohibited are as bo th in manual and autom atic operation.

(

1) Stored Stroke Limit

To use the stored stroke limi t fu nction, the axis movable area is set by parame te rs wit h the

coordinate values in the machine coordinate system. Th e a rea outside the set bou nda ry is
established as the entry prohibited area. If an axis enters the entry prohibited area, the
function stops axis movement and displays an alarm message. The functi o n is made va lid
upon completio n of th e manua l re f er en ce point return after the power is turned ON. In
automatic operation, if even o ne axis caus es the alarm, all axis are stopped.

In manual operati on, only the axis tha t caused an alarm is stopped.

FIGURE 1.2.3. 1: Stored Stroke Limit

1 - 10

YASNAC PCNC Operating Manual Chapter 1: Outline of YA SNAC System

(2) Stored Stroke Limit B, C (G22, G23) *

The area either outside or in s id e the boundary set by par ameters or by the commands in a

program is established as the entry prohibited area. The boundary is set with the coordi­nate va lues in the m achine coordinate system. W h ether the entry prohibited area is esta b­lished outside or inside the boundary can be determined by the setting for a par ameter.
The function is made valid upon completion of the reference point return after turning ON
the power.

• With the stored stroke limit C, set the boundary of the area and inside or outside the

boundary by parameters.

• Accord in g to the setting for the parameter or the input signal , one of the stor e d str o ke

limit C (third to fifth prohibited area ) ca n be ma de valid.

1.2.4 Interlock Inputs

The interlock input is the signal used to disable axis mov em ent, and is provided for each axis.

• When an axis is interlocked during movement, it is stopped after deceleration.

• When the interlock is re leased, the axis con tinues mo ving to co mplete th e remainin g com-

mands. Upon com ple tion of the commands, the program advances to the next block.

• For simu ltaneous two or three axis interpolation commands, interpolation operation is dis­abled if one of the s e two or three axis is int erlocked.

(1) OPTIONAL STOP Switch ON

When the OPTIONAL STOP switch is ON, the machine stops operating with the CYCLE
START lamp on the mach ine operatio n pane l lit after the execution of the block that
includes M01. Th e CYCLE START lamp goes OFF if the FIN signal is returned. The
operatio n r es tarts when the CYCLE START switch is pr es s ed.

(2) OPTIONAL STOP Switch OFF

The M01 command is disregarded. If the O PTIONAL STOP switch setting is changed
during the exec ut ion of an automatic operation, it is disregarded for the block presently
executed. Th e new setting becom es va li d from the block which is r ea d aft er the switch
setting has been changed.

2.7.2 Optional Block Skip

The OPTIONAL BLOCK SKIP sw it ch i s used to set whether or not the dat a in the block which
includes the “/” (slash) code should be disregarded in automatic operation. Note that if the switch
setting is changed during operation, the new setting is not valid for the blocks having been read to
the buffer area.

(1) OPTIONAL BLOCK SKIP Switch ON

When the OPTIONAL BLOCK SKIP switch is ON, the commands specified after the “/”
(slash) code are disregarded (up to the end of the block). For the blocks in which the “/”
code is specified, the commands specified preceding the “/” code are execut ed.

(2) OPTIONAL BLOCK SKIP Switch OFF

The blocks whi ch include the “/” (slash) code are executed. If the OPT IONAL BLOCK
SKIP switch setting is changed during the execution of an automatic operation, it is
disregarded for the block presentl y executed and also for the bloc ks ha ving been read to
the buffer area. Th e new setting becomes valid from the block wh i ch i s rea d aft er the
switch setting has been changed.

and OFF the block skip function for the individual designation of “/2” to “/9”.

2.7.3 Dry Run

When automatic mode operation (TAPE, MEM, MD1) is executed with the DRY RUN switch
set ON, feedrates specified in a program are disregarded and axis move commands are executed
at the fe ed rate set w ith the JOG FEEDR ATE sw itch. Sin ce the F cod e s p ecified i n a p r ogram is
displayed during the execution of a program, the program can be checked efficiently by using this
function.

Feedrate to be used in posit io ning (G00) can be selected from the rapid traverse rate or jo g feed­rate according to the setting for parameter pm2000 D0 as indicated in T able 2.2.

2.8 Operation Intervention During Automatic Operation

This section descri bes the procedure used fo r ma nua l and MDI operation int e rve nti on during
automatic operation.

CAUTION!

• Do not restart automatic ope r at ion after stopping automatic operation and then performing “tool
selection” in manual operation or “1 line MDI” operation.

The r eas on f or this is that the “tool s el ect io n” operation may cause the coordinate system to be c hang ed, leading
to unexpected operation if automatic operation were restarted. This could cause tool damage due to interference
and accidents causing personal injury.

Reset the NC after a ny manual interven tion.

• After stopping automatic opera tion and performing a manu al int er vention, do not restart autom at ic
operation without resett in g first.

If automatic operation is started with the “mirror image” or “manual absolute” function in effect, unexpected opera­tion maybe performed. This could cause tool damage due to interference, and accidents causing personal injury.

Reset the NC after any manual intervention.

2.8.1 Manual Ope r ation Intervention during Auto matic Operation

operation, the axes are decelerated and stopped immediately. When the operation
mode is chan ged from one automatic mode to anothe r automatic mod e, operation
stops at the block end.

2. If automatic operatio n is restarted without returning the axes to the previously located
position after manual operation intervention, how the tool paths to be generated after the
restart of automatic operation differs depending on the setting of the MANUAL ABSO­LUTE switch on th e machine operation panel. For details of the switch, refer to 2.8.4,
“Manual Absolute”.

3. In the manual mode, l-line MDI operation is possible. For details of the operation, refer
to 2.5.4, “1-line MDI”.

optionally, simultaneous 3-axis operation is allowed.

ì

Select the axis feed distance per graduation of the pul se ha ndle by placing the
MANUAL PULSE MULTIPLY switch on the machine operation panel at an
appropriate po sition. By this switch, it is possible to select 1, 10, or 100 pulses
per graduation of the ma nual pulse generat or.

ö

When the pulse handle is turned during t he execution of autom atic operation, move­ment of the axis which is selected in step

ó

above is added to the axi s mov e di stance
specified in the pro g ra m. W hen the pulse handle is turn ed in the clockwis e di rection,
the selected axi s moves in the positive direction and when it is turned in the counte r­clockwise dire ct ion, the axis, moves in the nega t ive direction.

ú

Restart the automatic operation after turning the AUTO MODE HANDLE OFFSET
switch OFF. Succeeding operation is executed with the axis shifted by the pulse han­dle operation . W he n th e coordinate system set-up command (G92, etc.) is executed
after, the shift amount is not included, but the coordinate system is set according to the
specified values.

2.8.4 Manual A bsol u te

If a cutting tool is moved manually by interrupting automatic operation, how the manually moved
distance should be treated when restarting automatic operation can be determined by the setting of
the MANUAL ABSO LUTE swit ch on the mac hine operat ion panel.

(1) MANUAL ABSOLUTE Switch ON

After the intervention of manual operation, the program coordinate system is not changed.
Subsequently, the remaining com mands in the interrupte d bl ock are executed by shifting
from the programmed path when automatic operation is restarted. When the block
appearing next to the operation restarted block is the circular interpolation block (G02,
G03), circular interpolation is exec ut ed w ith the paths shifted from th e programmed
paths.Wh en the G00 or G 01 mod e com man ds are gi ve n, the s hif t dis tan ce is can cele d, an d
the path s return to th e progra mmed paths.

3.1USER INTERFACE OVERVIEW

The MMI is divided into several areas. At the very top i s the stat us ba r, which displays system
status and alarm and warning messages. Below the status bar is the toolbar, which provides quick
and easy access to comm onl y use d functions such as copy and undo. The top level menu buttons
and the Reset button appear at the botto m of the scre en. Along the right hand sid e a re the second
level menu ite ms and oc cas ional ly, shortcu t butt ons to othe r scre ens. The rem ainde r of the MMI is
what will be referred to as the screen. This area changes based on what is selected in the top and
second level menus. Thi s chapt er provides a detailed descript io n of th ese components.

3.1.1 Status Bar

The status bar occupie s the top of the scre en, and displays data pertaining to the state of the sys­tem, as shown in Figure 3.1. 1. 1 on pa ge 7. It is split into sections that displ a y the bat t ery indica­tor, NC execution status, motion stat us, alarm me ssage, warning message time a nd da te .

FIGURE 3.1.1.1. Status Bar

3.1.2 Battery Indicato r

At startup, if there is a battery alarm, a broken batter y icon is displayed. Otherwise, a solid
battery is shown to indicate that everything is normal. After two minutes, this normal battery

indicator wil l disappear. If a battery alarm occurs, a red "Batter y Ala rm" message is displaye d in
the warnin g message ar ea. If other warnings occur whil e the batter y alarm exists, they will tempo­rarily overwr it e the battery alar m, but it wi ll be redi splayed when they are cl eared.

3.1.3 NC Execution Status

The execution status area (otherwise known as “Running status 1”) can have several va lu es, as
indicated by Table 3.1.3.1 on page 7.

3.1.5 Alarm Message

When an alarm oc curs, it is displayed in the ala rm message area with black text on a red ba ck­ground. If there are multiple alarms, only the highe st priority alarm i s sho wn. To get more infor­mation about the currently shown alarm , or to see what other al arm s m ay have occurred, use the

Alarm button to view the Alarm:NC Alarm screen.

3.1.6 Warning Message

When a warning oc curs, the text is displayed here on a yellow background. Warn ing messages
clear after 3 seconds. Warnings indicate a lower priority error which doe s not cause operation to
stop. Some common warning messages ar e shown in “Common Warning Messages” on page 9.

When th e system is in MDI mo de, multip le line MDI d ata can be entered in the progra m display
area of both the Run:Production and Run:Proveout screens. Editing in the program display area is
identical to editing in the Program:Editor screen. Several parameters affect how MDI mode
behaves; these are listed in Table 3.1.9.2 on page 13. The contents of the MDI buffer are not lost
when switching mode s, so an y text ent er ed while in MDI mode should still app ear w he n re-e nter­ing MDI mode. The white arrow indicates the line from which the program will be executed. If

start to change the num ber shown. This edit mo de is indicated by a yellow background. Pressing
the return key co mmits the new value. Pressin g th e escape key, or clicking outside of the field,
will cancel any chan ges made.

The number field alwa ys shows one digit to the left of the decim a l poi nt , and four to the right (or
three in me tric mode), e. g. , zero appear s as “0.0000.” Typing digits without entering a decimal
point causes the entere d di gi ts to shift in fro m the right (“0.0001,” the n “0.0012,” then “0.0123,”
etc.). When the decimal key is pressed, the previously entered digits will jump to the left of the
decimal, leaving four zeros to the rig ht.

The minus key acts li ke the change-sign key on a calculator. No matter whe n it is pressed, it
always ch anges the sign of the current num b e r.

Whenever t he de cimal key is pr esse d, a deci mal is pla ce d at th e cur ren t inse r tion poi nt. A ny p rev i­ous decimal disappears. If the decimal is pressed accidentally, pressing backspace will restore the
previous one. In cases whe re an entered value is invali d (for examp le, if it’s out of some specified
range) an error messag e will be shown onc e Ente r is pre ssed.

Some instances of number fields can be found on the Tools:Offsets and Setup:Workshift screens.

3.2.6 File Browser

Many scre en s in the use r interface require a f ile to be selected from a direct ory. These s creens use
a file browser, which is a co ll ec ti on of component s t ha t ca n be used to chan ge di rectories and
select items within directories. Whil e th e imp lementation may dif fer slightly from scre en to
screen, there are some basic components that all file browsers share. The Save As dialog shown in
Figure 3.2.6.1 on pa ge 24 is duplicated here to serve as an exampl e fi le brow se r. Instances of
other file browsers are the tabs on the Program:File screen and the dialogs that a ppear when New
or Copy This are pressed on the Program:Editor screen.

The file browser perm it s navigation to the files in the t op-level directories sh own in the Save In
(or Look In or Directory) drop-d ow n m enu, and files in any subdirectories of the top-level direc­tories. T o change directories, first select the top-level directory using the Save In drop-down
menu. Whenever a directory is selected, its contents are displayed in the file list area below the
Look In drop-down menu. In the file list area, a sub-directory can be opened by touching to high-

light the subdirectory to enter, then clicking on t h e Open Folder b utton. To select a fi le,
touch it to highlight it. The current directory name for the file browser may be displayed on some

screens. Other screens, such as the Save As dialog, may also display the sele cted file.

When moving through a directory tre e, it may be desirable to go back up to the parent
director y. The Up One Level button is used to do this. When the current directory is a
top-level directory, this button is disabled.
