G CODE PREVENTING BUFFERING

Overview

By specifying G04.1, buffering of the following block from the block of G04.1 is prevented until
finishing the block of G04.1. (At the following, preventing buffering by G04.1 is called non-buffering
command by G code. On the other hand, preventing buffering by M codes, command of only G31,
command of only G53 and etc. are called non-buffering commands of normal.)

The processing time of non-buffering command by G code is reduced compared with non-buffering
commands of normal. Also, the position of releasing preventing buffering can be specified by the distance
to go in the previous movement block. Therefore, the cycle time of automatic operation can be reduced by
using non-buffering command by G code instead of non-buffering commands of normal.

Specification

By specifying G04.1, the block which includes G04.1 becomes the prevented block of buffering.

Format

G04.1 (P_

)

;

: The operation mode of G04.1.

Compatible operation to preventing buffering by command of only G31 or G53 is
possible when P1 or P2 is specified with G04.1 in the same block.

P1: Compatible operation to preventing buffering by command of only G31.

P2: Compatible operation to preventing buffering by command of only G53.

However, alarm PS2085, “G04.1 FORMAT ERROR” occurs when P code except
P1 and P2 is specified.

: Distance to go for releasing preventing buffering (Synthetic distance to go in all
axis)

However, alarm (PS2085) occurs when the address I is specified in the state of
setting the bit 5 (MRR) of parameter No.11279 to 0.

NOTE

1 When P1 is specified, the system variables (#100151 to #100182) of skip

position are updated by executed position of the block that includes G04.1.
(When the system up to 20 axes, the system variables (#5061 to #5080)
compatible with FS16 is uploaded too.)

2 About preventing buffering by M codes or command of only G31 or command of

only G53, those behaviors are different respectively. When each preventing
buffering is exchanged for G04.1, it is necessary to use the compatible operation
mode.

3 Unit system as for the address I depends on the reference axis.
4 The address I is commanded by radius value regardless of diameter/radius

specification of the reference axis.

5 Positive value should be specified as for the address I. If negative value is

specified, the command of the address I is invalid.

6 The command of address I is invalid when the previous block of G04.1 is not the

movement command.

Explanation

About G04.1

G04.1 is a one-shot G code. When the commands except sequence number, P codes and comment are
specified with G04.1 in the same block, alarm PS2085, “G04.1 FORMAT ERROR” occurs.

About processing time

Because the processing time of non-buffering command by G code is reduced compared with
non-buffering commands of normal, the execution time of the block which includes non-buffering
command is reduced.

Speed-up of non-buffering command by G code invalid signal NHSW<G0579.6>

Speed-up of non-buffering command by G code is invalid when Speed-up of non-buffering command by
G code invalid signal NHSW<G0579.6> is set to “1”. And the processing time of non-buffering
command by G code is equal with non-buffering commands of normal.

Suppressing single block stop

Single block stop is not performed in G04.1 block when bit 6 (MSB) of parameter No.11279 is set to 1.
In this case, the function of preventing buffering in G04.1 block is not invalid.

NOTE

Single block stop is not performed in G04.1 block regardless of the state of
#3003 when bit 6 (MSB) of parameter No.11279 is set to 1.

When parameter MMR is set to 0

If G04.1 is specified just behind the movement block, the buffering of the block behind G04.1 is started
when the movement block finishes and each axis reaches to in-position.

Example)
In case of the following program, the buffering of the block behind N03 is started when the movement
command of N02 finishes and each axis reaches to in-position (N02 block finishes).
Therefore, the macro statement of N04 is executed after finishing N02.

When parameter MMR is set to 1

If G04.1 is specified just behind the movement block, the buffering of the block behind G04.1 is started
when the distance to go of the previous movement block reaches to the specified distance to go (distance
to go is specified by address I).

Example)
In case of the following program is executed, the buffering of the block behind N03 is started when the
distance to go of the movement command of N02 reaches to the distance to go (distance to go is specified
by address I).
Therefore, the macro statement of N04 is executed after reaching the distance to go of N02 to 3.0mm or
below.

N01 G90 G00 X0 Y0
N02 G01 X100.0 Y100.0 F1000.0
N03 G04.1 I3.0
N04 #100=#101+#102
N05 G01 X0.0 Y200.0 F1000.0

…

And, if the following command is specified in the blocks which are ahead or behind G04.1 block, the
movement commands are overlapped.
-

Cutting feed – Cutting feed block

Rapid traverse – Rapid traverse block with rapid traverse block overlap

Movement block – Movement block with smart overlap

NOTE

1 The delay occurs from starting the buffering of the block behind G04.1 to

executing it. And, the delay time is uneven.

2 When the distance to go by the address I is short, the movement command

might be not overlapped.

Limitation

Display of the currently executing program

The block of non-buffering command by G code is not displayed in the currently executing program.
However, the block of non-buffering command by G code is displayed in the currently executing program
when speed-up is invalid by the condition which is described in “Condition to treat non-buffering
command by G code as non-buffering commands of normal”.

Condition to treat non-buffering command by G code as non-buffering commands

of normal

When one of the following conditions is satisfied, speed-up of non-buffering command by G code is
invalid, and the processing time of non-buffering command by G code is equal with non-buffering
commands of normal. Moreover, non-buffering command by G code is treated as non-buffering
commands of normal.
-

Speed-up of non-buffering command by G code invalid signal is set to “1”.

The single-block operation is enabled.

Non-buffering command by G code is specified in the same block as the program number.

In manual handle retrace function, the checking mode synchronizing an operation with a manual
handle pulse is selected.

Animation or path drawing of dynamic graphic display is operated.

Bit 7(HMA) of parameter No.11279 is set to 1, and non-buffering command by G code is specified
during Relation of cutter compensation, Multiple repetitive canned cycle G70 to G73.

Manual handle retrace function

In  Manual handle retrace function,  a  backward movement cannot be executed while  the block of
non-buffering command by G code is executing except the checking mode synchronizing with a manual
handle  pulse.  The backward movement ends  when an operation enters  the next block of non-buffering
command by G code during the backward movement. And ‘RVED’ is displayed.
However, in the checking mode synchronizing with a manual handle pulse, the backward movement can
be executed when non-buffering command by G code  was executed once during  forward movement,
because the non-buffering command by G code is treated as non-buffering commands of normal in this
case.

Retrace

The backward movement cannot be executed by Retrace function in the block of non-buffering command
by G code. The backward movement ends when the next block of non-buffering command by G code just
starts executing during the backward movement. And ‘RVED’ is displayed.

Relation of cutter compensation

Non-buffering command by G code cannot be specified during the following cutter compensation
functions. Alarm PS0010, “IMPROPER G-CODE” occurs when such a command is specified. Use
non-buffering commands of normal during the following cutter compensation functions, or set bit 7
(HMA) of parameter No.11279 to 1.
-

Cutter compensation and tool nose radius compensation

NOTE

Non-buffering command by G code cannot be specified just after the cancel
command of cutter compensation, tool nose radius compensation. Moreover,
non-buffering command by G code cannot be specified while the vector of cutter
compensation is being held.

Multiple repetitive canned cycle

Non-buffering command by G code cannot be specified during Multiple repetitive canned cycle G70 to
G73. Alarm PS0010 occurs when such a command is specified. Use non-buffering commands of normal
during Multiple repetitive canned cycle G70 to G73, or set bit 7 (HMA) of parameter No.11279 to 1.

Chamfering and corner R, Optional chamfering and corner R and Direct drawing

dimension programming

In the condition to treat non-buffering command by G code as non-buffering commands of normal, alarm
PS0051, “MISSING MOVE AFTER CNR/CHF” occurs when non-buffering command by G code is
specified during Chamfering and corner R or Optional chamfering and corner R. And alarm PS0312,
“ILLEGAL COMMAND IN DIRECT DRAWING DIMENSIONS PROGRAMMING”occurs when
non-buffering command by G code is specified during Direct drawing dimension programming.

Block start interlock signal

Block start interlock signal

*BSL<Gn008.3> is invalid for non-buffering command by G code. However,

block start interlock signal

*BSL<Gn008.3> is valid in the condition to treat non-buffering command by

G code as non-buffering commands of normal.

When the speed-up is invalid

When the speed-up for G04.1 is invalid, the address I is ignored even if the address I is specified.
Example for the ignoring)
-

Speed-up of non-buffering command by G code invalid signal NHSW<G0579.6> is set to “1”

Feed hold stop

When a feed hold stop is operated in the previous block of G04.1, the operation of G04.1 after restart is
changed according to the number of blocks read ahead.
<When the number of blocks read ahead is 1>

The address I is ignored.

The address I is not ignored.

When a feed hold stop is operated in the previous block of G04.1, and the number of blocks read ahead is
1, the address I in the block of G04.1 is ignored.

Synchronous, composite, and superimposed control, Axis synchronous control,

Flexible synchronization control
