FOREWORD

This manual describes cautionary items that must be taken into consideraticm when operating
the YASNAC J300L (with basic NC operation panel, 9-inch CRT) as well as the basic config­uration and operation procedure of it.

Some information is presented in tables in the Appendix so that readers can easily find the
necessary information. In the specification table, section numbers are given for each specifi­cation to allow quick access to a detailecl explanation if necessary.

The YASNAC J300L comes with a programming manual in addition to thi~;operating manu­al. Use these manuals in conjunction with each other to ensure productive operation.

CAUTIONS

This manual describes all the option functions (identified by the “*” symbol) but some of
these may not be available with your YASNAC J300M. To determine the option functions
installed in your NC, refer to the specification document or manuals published by the ma­chine tool builder.

Unless otherwise specifiecl, the following conditions apply in programming explanations
and programming examples.

. Metric system for input and metric system for output/moveme.~t

●

: Zero point in the base coordinate system

+

●

: Reference point

@

Yaskawa has made every effort to describe individual functions and their relationships to oth­er functions as accurately as possible. However, there are many things ttat cannot or must
not be performed and it is not possible to describe all of these. Accordingly, readers are re­quested to understand that unless it is specifically stated that something can be performed,
it should be assumed that it cannot be performed.

Also bear in mind that the :performance and functions of an NC machine tool are not deter­mined solely by the NC unit. The entire control system consists of the mechanicals ystem,
the machine operation panel and other machine related equipment in addition to the NC.
Therefore, read the manuals published by the machine tool builder for derailed information
relating to the machine.

~ CAUTION

Page

Before carrying out cutting operation with a new program, confirm

safety by performing single block operation and dry run operation.

If this check operation is not performed, unexpected operation maybe per­formed due to mis-setting of the amount of offset, leading to tool damage
due to interference, and resulting accidents involving injuries to perscm­nel.

The end user must not change parameters relating to machine ac-

curacy, travel axis control and spindle axis control.

The NC parameters are set to the optimum values for each machine, and
changing them could therefore result in unexpected operation. This could
cause tool damage due to interference, and resulting accidents involving
injuries to personnel.
Reset the NC after any manual intervention.

Strictly observe the cautions in the user’s manual when using pro-

gramming functions.

Ignoring these cautions could lead to accidents involving injuries to per­sonnel and malfunctions.

PROTECTIVE

FUNCTIONS

1.2.1

1.2.2

Emergency Stop

Press the emergency stop button immediately if a problem occurs with the NC or sys­tem. The execution of all commands stops instantaneously when the emergency stop
button is pressed. Servo power supply of the NC is shut OFF and dynamic broke is applied
to stop all mechanical movement. In the emergency stop state, the NC is in the alarm state
“3002”. In the state the emergency stop signal input (CN02-19 pin on JANCD-JCP03 board)

is “opened”, the NC stops the entire operation, and turns OFF SVMX (CN2-17 pin on
JANCD-JCP03 board) and BKX (CN-18 pin on JANCD-JCP03 board).

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 and the function stops axis feed operation in response

to this input. The axis reached and stopped at the travel limit can be moved manually

into the axis movable range.

When the overtravel input is “opened”, axis move is stopped in the manner as indicated in

Table 1.1. In response to this input, the alarm output (ALM) is “closed” and the correspond-

ing alarm message is displayed on the screen.

If the overtravel input 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, and the
alarm output and display are canceled.

1.2 PROTI:CTIVE FUNCTIONS

1. After the occurrence of an alarm due to the “open” of the overtraval input, the M,
S, and T code read output signals (MF, SF, and TF) are not turmd OFF.

2. If it is necessary to interrupt the operation called by M, S, and/or T code, set the
interlock by an external sequence.

3. The alarm numbers at the occurrence of overtravel are 2001 to 2035. If the over-

travel alarm occurs, axis move is stopped. Note that the servo is Ilot turned OFF.

1.2.3 Stored Stroke Limit

To ensure improved safety in operation, the function prevents axes from l>ntering the preset
entry prohibited areas both in manual and automatic operation.

The area either inside or outside the boundary specified by parameters or either G36 or
G38 is defined as the entry prohibited area. If an axis enters the defined entry prohibited
area, an alarm (“2011” to “2015”) occurs. By the setting of “pm500(j D6 = l“, the entry
of an axis into the entry prohibited area does not cause an alarm and only the stroke
check monitor output signal (#3640, #3641) is output.

Entry prohibited area

The area outside the boundary set by the parameters for entry prohibited area No.

1 (stored stroke limit A) is defined as the entry prohibited area. Generally, this is
used instead of overtravel limit. The parameters set the upper limit point Al and
lower limit point B1.

Interlock inputs

The interlock input is the signal used to disable axis movement, and is pro!:ided for each axis.

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

● When the interlock is released, the axis continues moving to complete the re-

maining commands. Upon completion of the command:,, the program ad­vances to the next block.

● For simultaneous three axis interpolation commands, interpolation operation

is disabled if one of these two or three axes is interlocked.

the reference point return should be executed.

2. The axis for which reference point return has been completed can be moved in the
reference point return direction manually only if the reference point return switch
is turned OFF.

3. If commands have been read to the buffer area during automatic operation, manu­al reference point return must not be executed. If manual return operation is

2.5.3 Manual Reference Point Return to the Second Reference Point*

The axes are automatically positioned at the second reference point. This operation allows
positioning at the second reference point independent of the present axis position, whether
it is in the negative side or positive side from the second reference position. Follow the proce­dure indicated below.

@ Select thejogorrapidmode byplacingthe MODE SELECT switch in the JOG

or RAPID position.

@ Turn ON the ZRN2 (second zero point return request) switch on the machine

operation panel.

@ Keep the JOG switch corresponding to the axis and direction of reference

point return. The corresponding axis is positioned at the second zero point at
the jog feedrate or rapid traverse rate according to the selected mode.

● If the ZRN2 switch is turned OFF while an axis is moving to the second refer-

ence point, the axis stops moving. To restart the second reference point return
operation, turn ON the ZRN2 switch and turn OFF the JOG switch having
been pressed once, then press it once again.

● If the JOG switch is pressed again to be turned OFF while the X-axis is moving

to the second zero :point, the axis stops moving. In this case, press the JOG
switch again to turn it ON, and the X-axis restarts moving to the second zero
point. With the Y- and Z-axis, this is also applied.

2.6 AUTOMATIC OPERATION (1)

This section describes basic information necessary for performing automatic operation.

~, CAUTION

. Before carrying out cutting c)peration with anew program, confirm safety by per-

forming single block operation and dry run operation.

If this check operation is not performed, unexpected operation may be performed due to
mis-setting of the amount of cdlset, leading to tool damage due to interference, and re­sulting accidents involving injuries to personnel.

● Strictly observe the cautions in the user’s manual when using programming

functions.

Ignoring these cautions could lead to accidents involving injuries to personnel and mal­functions.

2.6.1 Preparation of Automatic Operation

After turning ON the power, the axes must be positioned at the start point defined in a pro­gram before starting automatic operation. Set the coordinate system to be used for machining
either manually or by specif ying appropriate commands in a program. Several examples are
given below to explain how the the coordinate system should be set. For details, refer to the

manuals published by the machine tool builder.

(1) Setting the Coordinate System

The origin of the coordinate system to be used for executing the commands should be
set,

(a) When G50 is not specified in the program

The coordinate system for which the origin is set at other than the reference point
for the program not containing the coordinate system setting command (G50) is
called a coordinate system for machining. The procedure for setting a coordinate
system for machining is indicated below.

Return the axes to the reference point by following the manual reference point
return procedure (see 2.4.2.).

Select the MDI mode by placing the MODE SELECT switch on the machine
operation panel in the MDI position.

2.7 AUTOMATIC OPERATION (2)

2.7.1

Optional Stop

The OPTIONAL STOP iwitch is used to select whether or not the MO1 (o~tional stop) com­mand should be executed in the automatic mode (TAPE, MEM, MDI).

OPTIONAL STOP Switch ON

(1)

When the OPTIONAL STOP switch is ON, the machine stops operating with the
CYCLE START lamp on the machine operation panel lit after the execution of the block
that includes MO1. The CYCLE START lamp goes OFF if the FIN signal is returned.
The operation restarts when the CYCLE START switch is pressed.

(2)

OPTIONAL STOP Switch OFF

The MO1 command is disregarded. [f the OPTION.AL STOP switch :setting is changed
during the execution of an automatic operation, it is disregarded for the block presently
executed. The new setting becomes valid from the block which is read after the switch
setting has been changed.

2.7.2 Optional Block Skip

H

The OPTIONAL BLOCK SKIP switch is used to set whether or not the data in the block
which includes the “i” (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 buffer area.

2.7.3 Dry Run

When automatic mode operation (TAPE, MEM, MDI) is executed with the DRY RUN
switch set ON, feedrates specified in a program are disregarded and axis move commands
are executed at the feedrate set with the JOG FEEDRATE switch. Since the F code specified
in a program is displayed during the execution of a program, the program can be checked
efficiently by using this function.

Feedrate to be used in positioning (GOO)can be selected from the rapid traverse rate or jog
feedrate according to the setting for parameter pm2000 DO as indicated in Table 2.2.

2. When the optional block skip B function is selected, the switches are provided
corresponding to “/2” to “/9” individually and by using these switches, it is pos­sible to turn ON and OFF the block skip function for the individual designation
of “/2” to “/9”.

2.7.4 Machine Lock

The MACHINE LOCK switch allows the program to be executed in the following manner
– to operate the machine with the present position data fixed, or to execute the program to

update the present position data withoui actually operi~ting the machine. The switch can be
operated only while the operation is stc)pped in the block stop or feed hold state.

2.7 AUTOMATIC OPERATION (2)

(1) MACHINE LOCK Switch ON

As the program commands are executed manually or automatically, the position data
are updated according to the execution of the commands while the machine is not actu­ally operated. With this setting, the M, S, and T functions are executed normall y. This
are used for manually presetting the display or for checking the tape. Note that the refer­ence point return operation is not executed if the switch is placed in the MACHINE
LOCK position.

OPERATION INTERVENTION DIJIRING AUTOMATIC
OPERATION

This section describes the procedure used for manual and MDI operation intervention during
automatic operation.

~ C,AUTIO-kl -

Do not restart automatic operation after stopping automatic operation and then

~

performing “tool selection” in manual operatiorl or”1 line MDI” operation.

Thereasonforthis is that the’’tool selection’’ operation may cause the coordinate system
to be changed, leading to unexpected operation if automatic operatiorl were restarted.
This could cause tool damage due to interference, and resulting accidents involving in-

juries to personnel.

Reset the NC after any manual intervention.

~ After stopping automatic operation and performing a manual intervention, do

not restart automatic operation without resetting 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 resulting accidents involving injuries to personnel.
Reset the NC after any manual intervention.

2.8.1

Manual Operation Intervention during Automatic Operation

To carry out a manual operation during automatic operation, follow the sieps indicated be-

Interrupt the operation by using the FEED HOLD or SINGL~3-BLOCK switch
on the machine operation panel.

Record the position where the operation has been interrupted after displaying
the present position data by pressing the [EXTERN] (f3) key of the POS. job
at the COMN screen.

Select the manual mode (RAPID, JOG, STEP or HANDLE) with the MODE
SELECT switch on the machine operaticm panel.

Return the axes to the position where manual operation (selt 2.3 “MANUAL
OPERATION (l)”.) has been started (the position recorded in step @)).

Return the MODE SELECT switch to the operation mode (MEM or MDI)
position selected before manual operation intervention.

Press the CYCLE START switch on the machine operation panel to restart the
interrupted automatic operation.

2.8.2 MDI

1. If the operation mode is changed from automatic to manual without stopping the
operation, the axes are decelerated and stopped immediately. When the operation
mode is changed from one automatic mode to another automatic mode, operation
stops at the block end.

2. If automatic operation 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 the 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, “l-line MDI”.

Operation Intervention during Automatic Operation

To carry out an MDI operation during automatic operation, follow the steps indicated below.

Interrupt the automatic operation by turning the SINGLE-13LOCK switch on
the machine operation panel ON. The machine stops after the completion of
the block being executed when the switch is turned ON. In this case, several
blocks of commands might have been read into the buffer area.

2.8 OPERATION INTERVENTION DURING AUTOMATIC OPERATION

2.8.3 Automatic Handle Mode Offset *

During automatic operation (TAPE, MD1, MEM), distance of axis shift carried out by using
the pulse handle can be added by this function. This function allows compensation for errors
in mounting workpieces, etc. Follow the procedure indicated below.

Turn ON the AUTO MODE HANDLE OFFSET switch on the machine opera­tion panel.

Select the axis to be moved with the HANDLE AXIS swirch on the machine
operation panel. If the simultaneous 3-axis control by using the pulse handles
is selected optionally, simultaneous 3-axis operation is allowed.

Select the axis feed distance per graduation of the pulse handle by placing the
MANUAL PULSE MULTIPLY switch on the machine operation panel at an
appropriate position. By this switch, it is possible to select 1, 10, or 100 pulses
per graduation of the manual pulse generator.

When the pulse handle is turned during the execution of a~.tomatic operation,

movement of the axis which is selected in step@ above

iIs added to the axis

move distance specified in the program. When the pulse handle is turned in
the clockwise direction, the selected axis moves in the positive direction and

when it is turned in the counterclockwise direction, the axis moves in the nega-

tive direction.
Restart the automatic operation after turning the AUTO MODE HANDLE

OFFSET switch OFF. Succeeding operation is executed v,ith the axis shifted

by the pulse handle operation. When the coordinate system set-up command

(G92, etc.) is executed after that, the shift amount is not included but the coor­dinate system is set according to the specified values.

After the intervention of manual operation, the program coordinate system is not
changed. Subsequently, the remaining commands in the interrupted block 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 executed with the paths shifted from the pro­grammed paths. When the GOOor GO1 mode commands are given, the shift distance
is canceled, and the paths return to the programmed paths.

2.9 AUTOMATIC OPERATIONS AT ENHANCED LEVEL

In this section, enhanced level functions of YASNAC J300 are described.

2.9.1 Return to the Setup Point

The function executes positioning at a jog feedrate at the position where the coordinate sys­tem has been established (setup point). If the SRN input signal is “closed”, axis movement

at a jog feedrate stops after the completion of positioning at the setup point. Further jog feed
is not possible unless the SRN input signal is “opened”.

2.9.2 Return to the Operation Interrupted Point*

The “return to operation interrupted point” function is provided to return the axes to the pre-

viously located position where automatic operation has been interrupted to carry out manual
operation for measuring the machined dimensions or removing chips.

r-7

Fig. 2.14 Return to Operation Interrupted Point

The operation procedure is explained below.

Interrupt the automatic operation by pressing the SINGLE-BLOCK or FEED
HOLD switch on the machine operation panel.

Select a manual mode by placing the MODE SELECT switch on the machine
operation panel in the JOG, RAPID, HANDLE, or STEP position.

Move an axis in the manual mode to retract the cutting tool appropriately.
Carry out required operation such as measuring the workpiece, removal of

chips, etc.
Turn ON the INTERRUPTION POINT RETURN switch cm the machine op-

eration panel.

2.9 AUTOMA1”IC OPERATIONS AT ENHANCED LEVEL

Press the MANUAL PULSE MULTIPLY switch on the machine operation
panel corresponding to the direction to the machining interrupted point (the
point where the operation mode has been changed from automatic to manual).
The axis moves to the machining interrupted point at the selected feedrate and
it stops moving when it reaches the machining interrupte,~ point.

Turn OFF the INTERRUPTION POINT RETURN switch on the machine op­eration panel.

Return the operation mode to an automatic mode and press the CYCLE
START switch on the machine operation panel. The automatic operation re­starts.

If the axes are positioned on the machining interrupted point, t~lrn OFF the IN-

1.

TERRUPTION POINT RETUllN switch. Otherwise, jog feed o~such axes is not
possible.

If the NC is reset after changing the operation mode from autonlatic to manual,

2.
the present position is taken as the machining interrupted point. This means that
the axes are positioned on the machining intermpted point and, subsequent] y,jog
feed operation is not allowed unless the IN~ERRUPTION POINT RETURN
switch is turned OFF.

If automatic operation is interrupted by manual operation for a second time after

3.
the automatic operation was once interrupted by manual operation and then the
automatic operation was recovered, the point where the operation mode was last
changed from automatic to manual is taken as the machining interrupted point.

2.9.3 Saving the Present Position Data

The signal to save the present pc~sition data is provided. When the PST input signal is
“opened”, the NC saves the present position data to the internal memory at the timing the
signal is opened. Then, it executes the following operation using the offset data written in
the MDI operation to store the result of operation to the offset data memory.

Value to be written into the offset data memory

= (Value input in the MDI operation) - (Present position value saved in the NC memory)

The present position data is cleareci and the LED stops blinking by the reset operation (press­ing the [RESET] key on the NC operation panel or “opening” the external reset input signal).

2.9.4 Program Restart *

By using the program restart function, it is possible to restart an interrupted operation in such
cases where execution is interrupted due to breakage of a cutting tool or to r{>startthe program
continuous] yfrom the block where the operation was stopped the previous day. By designat­ing a sequence number of the block, the function allows the program to be restated from the
specified block.

2.9 AUTOMATICOPERATIONSK” ENHANCEDLEVEL

(3) Remarks on Program Restadand Related Functions

The program restart function establishes various conditions during the execution of se­quence number search so that the ccmditions at the restart will be the same as those when
the program was interrupted. However, some program commands require extra care.
These are indicated below.

(a) Program restart position

The position for the restart of program is generated in the NC. ‘rherefore, the axes

are regarded to move as programmed during the search for the program restart posi­tion. If the function is executed in the mode called by the following G codes, the
point specified in a program and actual positioningpoint differ from each other and

in such modes, the point specified in the program is regarded as the end point: auto-

matic reference point return (G28), reference point return check (G27), return from

reference point (G29), second - fourth reference point return (G30), and machine

coordinate system (G53).

(b) Input signal

There are commands that perform different operations depending on the input sig-

nals. With one type of signal, the status at the start of search for the program restart

is retained, and with another type of signal, they are completely disregarded.

c The signals that retain the status at the start of search:

Mirror image (M95, M94), block delete,, machine lock, and F1-digit selection

● The signals that are disregarded:

Feed hold, single-block, auxiliary function lock, skip, program interrupt
(M91, M90), and optional stop

● The distance which the axes were moved before cycle star! is cancelled disre-

garding of the ON/OFF status of the marwal absolute signal and the commands
are executed in the workpiece coordinate system called al the completion of
search.

2-45

.— ....--.. ——. . ,-., ,- —.. —. ——. ——.. .

(c) Using a macroprogralm

When a microprogram is used, care must be paid on system variables.

●

All interface input/output signals (#1000 - #1031, #1032, #1100 - #1131, and
#1132) are processed as “O”.

●

Although the clock (#3001, #3002) is read and written normally, the time

Therefore, correct results cannot be expected.

count at the restart of the program is not guaranteed.

●

The control of single-block stop and wait for the completion of auxiliary func­tion (#3003) is disregarded and the specification of control is made invalid.

●

The control for feed hold, feedrate override, and exact stop (#3004) is disre­garded and the specification of control is made invalid.

●

Although the position data (#5000 - ) is read normally, the data generated in
the NC is used for the operation. For the servo error data (#5101 - #5105), “O”
is read.

●

Concerning the RS-232C data output 2 (BPRNT, DPRNT), if the program is
restarted at the RS-232C open command, an alarm occurs at the execution of
the RS-232C output command.

If the CYCLE ST~T switch is pressed while the PROGRAM RI ITURN switch
is ON, the warning message “RESTARTING PROG!” is displayed.

After the completion of search fc)rprogram restart, operation intervention is not

3.
allowed in other than manual mode until program restart is exacuted. If the
CYCLE START switch is pressed in the MDIl, TAPE or MEM mode, alarm
“0292” occurs and the message “IMPOSSIBLE TO START THE, COMMAND
WHEN RESTARTING PROGRAM” is displa yed.

If the PROGRAM RETURN switch is ON, it is not possible to move an axis

4.
manually. Operation of jog switches and manual pulse generator k disregarded.

When requesting the program restart, conditions such as the input signals and tool

5.
offset must be the same as those at the interruption of the program. Otherwise,
correct restart position and conditions cannot be established. Manual operation
that is carried out in the program restart operation is allowed only with the
MANUAL ABSOLUTE switch set ON.

During the search for program restart, the FEED HOLD switch and the SINGLE-

6.
BLOCK switch are disregarded. If the NC is reset during the search, the search
is interrupted immediately. If this occurs, it is necessary to request the program
to restart once again.

This function executes processing on the assumption that the coordinate system

7.
has been established correctly before the restart of operation. Therefore, if the
restart request is given without executing the reference point return after turning
the power ON, alarm “0411” to “:0415” occurs and the message “REFERENCE
POINT RETURN NOT COMPLETED” is displayed. With the incremental
command program, if the coordinate system setting command is not given at the

beginning of the program, the restart position cannot be generated correctly.

8.

If the sequence number given with the restart request is not found, alarm “0290”
occurs and the message “PROGRAM RESTART SEQUENCE N“LJMBERNOT
FOUND” is displayed.

9.

Upon completion of the search, if reference point return is executed by changing
the mode to manual, or if manual coordinate system setting is executed, alarm
“0291” occurs and the alarm message “COORDINATE SYSTHM SHIFTED
AFTER PROGRAM RESTART’ is displayed.

10.

Program restart is impossible for DNC operation., tape operation, and high-speed
cutting mode operation.

3.2.4 Key Buffer Edit Function

For the data keyed in by key operation and displayed at the key buffer area on the CRT screen,
insertion and deletion of characters are allowed. This key buffer area edit function is helpful
to correct the entered data in the following cases.

● The user finds an error immediately after keying in the data.

● The keyed in data could not be entered with the “INPUT ERROR!” warning

message displayed even when the [WRI key was pressed.

Key Buffer Cursor

—

underlined cursor is the key buffer cursor. It moves to the right as characters are keyed
in and is displayed after the last character.

(2)

With characters keyed into the key buffer area, the underlined cursor moves in response
to the operation with the cursor rightfleft keys. The underlined cursor is valid in the key
buffer area but not for the contents displayed on the screen. However, if there are no
characters keyed into the key buffer, the underline cursor is valid fclr the contents dis­played on the screen. Examples of the key buffe~ edit operation are explained below.
