SBV=1 : Single block operation in custom macro statements is suppressed using macro system variable

#3003. Execution of custom macro statements is stopped after each block execution.

NOTE

1 In the cutter or tool nose radius compensation mode, the block look-ahead

operation is performed even in single-block operation to calculate a path
intersection after offsetting. So, a macro statement is also executed when read in
advance. Therefore, turn off the cutter or tool nose radius compensation mode,
when the single block operation is enabled for custom macro statements by
SBM=1 or SBV=1.

2 When the single block operation is enabled for custom macro statements by

SBM=1 or SBV=1, a custom macro statement block is assumed to be an NC
statement block that does not involve movement. Therefore, the motion may
differ between the normal operation and the single block operation.

When M99 is executed by the single block operation, operation stops after executing the next block of
M99. However, when the single block stop is invalidated by the system variable #3003, and the single
block stop is validated again by the system variable #3003, the single block stop is done with the first
M99. However, when bit 0 (M99) of parameter No.11648 is set to 1, operation can be stopped with M99.
When the CNC is in the automatic operation stop state during single block operation, the mode can be
changed to manual data input (MDI), manual handle feed (HNDL), incremental feed (INC), or jog feed
(JOG), by using the mode select signals (MD1, MD2, and MD4).

NOTE

1 In the cutter or tool nose radius compensation mode, the block

look-ahead operation is performed even in single-block operation to
calculate a path intersection after offsetting. So, a macro statement
is also executed when read in advance. Therefore, turn off the
cutter or tool nose radius compensation mode, when the single
block operation is enabled for custom macro statements by SBM=1
or SBV=1.

2 When the single block operation is enabled for custom macro

statements by SBM=1 or SBV=1, a custom macro statement block

CAUTION

1 Operation in thread cutting

When the SBK signal turns to 1 during thread cutting, operation stops after
execution of the first non-thread cutting block after the thread cutting command.

2 Operation in canned cycle

When the SBK signal turns to 1 during canned cycle operation, the operation
stops at each positioning, approach, drilling and retreat instead of the end of the
block. The SPL signal turns to 1 while the STL signal turns to 0, showing that the
end of the block has not been reached. When the execution of one block is
completed, the STL and SPL signals turn to 0 and the operation is stopped.

3 When a parameter M99(No.11648#0) is set to 1, the tool path might be different

because of a single block operation and a continuous operation, when the block
where the movements do not exist is commanded just before or just behind M99
in the cutter compensation and tool nose radius compensation mode.

High-speed Program Check Function

Overview

High-speed program check function has following features.
-

The program format check and the stroke limit check are available without axes movements.

The program check is executed with the maximum feedrate of CNC system and without the
acceleration/deceleration regardless of the specified data.

After the program check is completed, the reference position return is not necessary because the
workpiece coordinate system preset is executed automatically at the end of the high-speed program
check mode.

B-64693EN-1/01

5. AUTOMATIC OPERATION

- 837 -

By this, after ending the high-speed program check mode, the automatic operation can be executed
with the data before the start of the high-speed program check mode.

Explanation

Basic operation procedure of the high-speed program check

(1)  Set the high-speed program check mode.
(2)  Perform a cycle start operation. The high-speed program check is then performed.
(3)  After program execution is completed and the check ends, the high-speed program check mode ends.

Start of High-speed program check mode

The high-speed program check mode is started under both of the following conditions.
-

The signal PGCK <Gn290.5> for high-speed program check is 1.

MEM or DNC mode is selected.

When the mode is except MEM or DNC mode, the high-speed program check mode is not started even if
the signal PGCK <Gn290.5> is 1.

End of High-speed program check mode

The high-speed program check mode is ended under one of the following conditions.
-

The signal PGCK <Gn290.5> is changed from 1 to 0.

A mode except MEM or DNC is selected during the high-speed program check mode.

NOTE

The alarm PS5365 occurs when the signal PGCK <Gn290.5> is changed while a
program is executing.

Program Check Start

The program check is started when the signal ST <Gn007.2> for cycle start signal is changed from 1 to 0
at the high-speed program check mode.
Then, the program execution is started without axes movements.

Stroke Limit Check

Following the stroke limit check is executed without axes movements during the high-speed program
check mode.
-

Stored stroke check 1

Stored stroke check 2, 3

Stroke limit check before move

NOTE

The stroke limit check during the high-speed program check mode is similar to
the normal stored stroke limit check. (The alarm 500 etc. occurs at exceeding the
stroke limit.)

As for the details of occurrence alarms, refer to chapter of stored stroke check in
Operator's Manual.

Program Check Feedrate

During the high-speed program check mode, the feedrate of program execution becomes the maximum
feedrate of CNC system regardless of the specified feedrate.
The feedrate clamp, override and dry run are not effective.

CAUTION

The program check execution feedrate at circle interpolation is according to the
bit 7 (PGF) of parameter No. 1490 setting.

NOTE

1 The execution time of dwell is the same as a normal operation.
2 The PS011 alarm occurs when there is no F command in a normal operation.

However, it is executed at maximum speed without the alarm in the high-speed
program check mode even if there is no F command.

Acceleration / deceleration

During the high-speed program check mode, the acceleration/deceleration after interpolation and before
interpolation is not executed regardless of the acceleration/deceleration setting value.
(Acceleration/deceleration time constant becomes to 0.)

Workpiece Coordinate System Preset

When the high-speed program check mode is ended, the workpiece coordinate system preset is executed
automatically.
Therefore, the program execution can be done without doing the reference position return after the
program check.

WARNING

When the coordinate system is set before the high-speed program check mode is
turned on by the work coordinate system setting G92 (machining center system
and G code system B or C of the lathe system), G50 (G code system A of the
lathe system) and the local coordinate system setting G52, their setting values
are deleted by the execution of the work coordinate system preset.

NOTE

1 When the bit 3 (PGR) of parameter No. 3454 is set to 0, set the bit 6 (WPS) of

parameter No. 3006 to 1 to do workpiece coordinate system preset at the end of
the high-speed program check mode. When the bit 3 (PGR) of parameter No.
3454 is set to 1, workpiece coordinate system preset is executed at the end of the
high-speed program check mode regardless of the bit 6 (WPS) of parameter No.
3006 setting.

2 When the bit 3 (PGR) of parameter No. 3454 is set to 1 in multi-path system, all

paths must be in the high-speed program check mode simultaneously. If some
paths are in the high-speed program check mode, the automatic operation can
not be executed in other paths.

Machine Coordinate Display For Program Check

During the high-speed program check mode, it is possible to change the display of machine coordinates
from the actual machine coordinates to the machine coordinates for the program check by setting bit 7
(PGM) of parameter No.11320.

B-64693EN-1/01

5. AUTOMATIC OPERATION

- 839 -

And it is possible to change the display of machine coordinate for each axis from the actual machine
coordinate to the machine coordinate for the program check by setting bit 4 (PGA) of parameter No.3115.

NOTE

1 When the signal EAX* <Gn136> for control axis select (PMC axis control) is set

to 1, the machine coordinate of the axis shows the actual machine coordinate
regardless of the parameter PGM and PGA setting.

2 The diagnosis data No. 301 (machine position) always shows the actual machine

coordinate (the machine position from the reference position) regardless of the
parameter PGM and PGA setting.

Display during High-speed program check mode

During the high-speed program check mode, "PRG-CHK" blinks on the lower right of the CNC display.

Tool life

If tool life management command or tool management command is specified during the high-speed
program check mode, tool life is not counted.

Auxiliary function

When the bit 6 (PGS) of parameter No. 3001 is set to 0, the auxiliary function is not executed during the
high-speed program check mode. This is same as when the signal AFL <Gn005.6> for auxiliary function
lock is 1. That is, M, S, T, and B function code signals and strobe signals are not output.
When the bit 6 (PGS) of parameter No. 3001 is set to 1, the M, S, T, and B function code signals and
strobe signals are output during the high-speed program check mode. This is same as the normal
operation.

WARNING

Please note that the spindle rotates by S command under the either of following
conditions during the high-speed program check mode. To prohibit the rotation of
the spindle in the high-speed program check mode, take countermeasure in PMC
ladder using the signal PRGMD<Fn290.5>.

-  Lathe system
-  Constant surface speed control is effective
-  T type gear selection method (bit 4 (GTT) of parameter No. 3706 =1)

CAUTION

1 When the bit 6 (PGS) of parameter No. 3001 is set to 1, the M, S, T, and B codes

are output to the PMC. Therefore, if it is not necessary to execute the M, S, T,
and B command during high-speed program check mode, please modify ladder
sequence not to execute M, S, T, and B code by referring to the signal <Fn290.5>
for the high-speed program check mode.

2 If M code (Parameter No.11275), which turns on each axis workpiece coordinate

system preset signal, is commanded in the high-speed program check mode with
bit 6 (PGS) of parameter No. 3001=0, the alarm PS5364 occurs. In the machine
that uses such a program, set bit 6 (PGS) of parameter No. 3001 to 1.

3 In case of using the tool management function, set bit 6 (PGS) of parameter No.

3001 to 1 and execute the window function (code 329) by T code and M code as
well as usually operation in order to execute the tool compensation correctly with
D99 and H99.

Data save at start of high-speed program check mode

When the bit 3 (PGR) of parameter No. 3454 is set to 1, the following data are saved at the start of the
high-speed program check mode.

•

Modal G-code

•

F, S, T, M, B, H, D-code

•

Tool life management data

•

Tool management data

•

Variable data changed by programmable data entry (G10)
-

Tool offset values

External workpiece origin offset values

Workpiece origin offset values (1 to 6)

Workpiece origin offset values of additional workpiece coordinate systems (1 to 48 or 1 to 300)

Rotary table dynamic fixture offset values (Machining center system)

Parameters

Tool data of the path interference check function (Lathe system and multi path system)

Workpiece coordinate system shift values (Lathe system)

Graphic parameters

•

Macro variables
-

Local variables #1 to #33

Common variables #100 to #149 (#199), #500 to #531 (#999)

NOTE

1 The data of the periodic maintenance screen are not saved.
2 When the bit 6 (PGS) of parameter No. 3001 is set to 1, the M, S, T, and B codes

are not saved.

3 In multi path system, the data in all paths is saved when one path becomes the

high-speed program check mode.

Data restore at end of high-speed program check mode

In case that the bit 3 (PGR) of parameter No. 3454 is set to 1, the data, which are changed during the
high-speed program check mode, are restored to the data at the start of the high-speed program check
mode when ending the high-speed program check mode.
By this, after ending the high-speed program check mode, the automatic operation can be executed with
the data before the start of the high-speed program check mode.
The data to be restored are the same as those of described on "Data save at start of high-speed program
check mode".

WARNING

1 In multi path system, the data in all paths is saved when one path becomes the

high-speed program check mode, and the data in all paths is restored when all
paths get out of the high-speed program check mode. That is, when there is
different timing of changing the high-speed program check signal
PGCK<Gn290.5> in each path, the completion of the high-speed program check
mode in a path might influence the operation of other paths. For instance, if the
high-speed program check mode of a path is turned off when machining is in
progress on another path, it might face dangerous situation because the data of
other paths during machining also changes. Therefore, in multi path system,
please keep the timing of the state of the high-speed program check mode
simultaneously in all paths when you set bit 3 (PGR) of parameter No. 3454 to 1.
Please do not have both paths of the high-speed program check mode and paths
of normal mode in a multi path system.

B-64693EN-1/01

5. AUTOMATIC OPERATION

- 841 -

WARNING

2 The coordinate value set by the work coordinate system setting G92 (machining

center system and G code system B or C of the lathe system), G50 (G code
system A of the lathe system) and the local coordinate system setting G52 is not
restored.

CAUTION

1 After restoring the data, the absolute coordinate is calculated from machine

coordinate by using the restored data.

2 In case that the relative position display is preset (the bit 3 (PPD) of parameter

No. 3104 is set to 1) in the coordinate system setting, the relative coordinate is
not restored and presets same value as the absolute coordinate.

3 The data of the periodic maintenance screen are not restored.
4 When the bit 6 (PGS) of parameter No. 3001 is set to 1, the M, S, T, and B codes

are not restored.

5 The save/restore of the data before/after the program check of the high-speed

program check function is realized by saving all data before the program check
and restoring all data after the program check. Therefore, even when the data is
changed without the program command such as the PMC window during the
program check, the changed data returns to the value before the program check.

Limitation

High-speed program check signal

The alarm PS5365 occurs when the signal PGCK <Gn290.5> is changed from 0 to 1 or from 1 to 0 while
a program is executing.

Stroke limit check

When a command that exceeds a stroke limit is specified in the high speed program check mode, an
overtravel alarm occurs after the stroke limit is exceeded regardless of the bit 7 (BFA) of parameter No.
1300 setting.
The process of the overtravel alarm cancellation is as follows.
(1) Change to the mode except MEM or DNC.

(2) Push

key or input reset signal.

The alarm cancellation of stroke limit check 1 is based on the bit 4 (OF1) of parameter No. 1301.
Therefore, when the parameter OF1 is set to 0, the alarm is cancelled by the above process and when this
parameter is set to 1, the alarm is cancelled automatically when the high-speed program check mode is
ended.

Bit 4 (OF1) of parameter No. 1301:

If the axis is moved into the allowable range after an OT alarm is generated by stored stroke check 1,
0:

The alarm is not canceled before a reset is made.

The alarm is immediately canceled.

Stroke limit check before move

When there is a movement command that exceeds the stroke limit in the high-speed program check mode,
an alarm of the stroke limit check before move and a usual overtravel alarm might occur at the same time.

Stored stroke check 2, 3

In case that there is narrow forbidden area, the alarm might not be able to be detected in the block which
crosses the forbidden area in the high-speed program check mode.
