LIMITATIONS
D MDI operation
The macro call command can be specified in MDI mode. During
automatic operation, however, it is impossible to switch to the MDI mode
for a macro program call.
D Sequence number
A custom macro program cannot be searched for a sequence number.
search
D Single block
Even while a macro program is being executed, blocks can be stopped in
the single block mode.
A block containing a macro call command (G65, G66, or G67) does not
stop even when the single block mode is on. Blocks containing arithmetic
operation commands and control commands can be stopped in single
block mode by setting SBM (bit 5 of parameter 6000) to 1.
Single block stop operation is used for testing custom macro programs.
Note that when a single block stop occurs at a macro statement in cutter
compensation C mode, the statement is assumed to be a block that does
not involve movement, and proper compensation cannot be performed in
some cases.
(Strictly speaking, the block is regarded as specifying a
movement with a travel distance 0.)
D Optional block skip
A / appearing in the middle of an <expression> (enclosed in brackets [
] on the right-hand side of an arithmetic expression) is regarded as a
division operator; it is not regarded as the specifier for an optional block
skip code.
By setting NE8 (bit 0 of parameter 3202) and NE9 (bit 4 of parameter
D Operation in EDIT mode
3202) to 1, deletion and editing are disabled for custom macro programs
and subprograms with program numbers 8000 to 8999 and 9000 to 9999.
This prevents registered custom macro programs and subprograms from
being destroyed by accident. When the entire memory is cleared (by
pressing the
RESET
and
DELETE
keys at the same time to turn on the power),
the contents of memory such as custom macro programs are deleted.
D Reset
With a reset operation, local variables and common variables #100 to
#149 are cleared to null values. They can be prevented from clearing by
setting, CLV and CCV (bits 7 and 6 of parameter 6001). System variables
#1000 to #1133 are not cleared.
A reset operation clears any called states of custom macro programs and
subprograms, and any DO states, and returns control to the main program.
D Display of the PROGRAM
As with M98, the M and T codes used for subprogram calls are not
RESTART
displayed.
D Feed hold
When a feed hold is enabled during execution of a macro statement, the
machine stops after execution of the macro statement. The machine also
stops when a reset or alarm occurs.

The BPRNT command outputs characters and variable values in binary.
(i) Specified characters are converted to the codes according to the
setting data (ISO) that is output at that time.
Specifiable characters are as follows:
- Letters (A to Z)
- Numbers
- Special characters (*, /, +, -, etc.)
An asterisk (*) is output by a space code.
(ii) All variables are stored with a decimal point. Specify a variable
followed by the number of significant decimal places enclosed in
brackets. A variable value is treated as 2-word (32-bit) data,
including the decimal digits. It is output as binary data starting from
the highest byte.
(iii) When specified data has been output, an EOB code is output
according to the setting code (ISO).
(iv) Null variables are regarded as 0.

The DPRNT command outputs characters and each digit in the value of
a variable according to the code set in the settings (ISO).
(i) For an explanation of the DPRNT command, see Items (i), (iii), and
(iv) for the BPRNT command.
(ii) When outputting a variable, specify # followed by the variable
number, then specify the number of digits in the integer part and the
number of decimal places enclosed in brackets.
One code is output for each of the specified number of digits, starting
with the highest digit. For each digit, a code is output according to
the settings (ISO). The decimal point is also output using a code set
in the settings (ISO).
Each variable must be a numeric value consisting of up to eight
digits. When high-order digits are zeros, these zeros are not output
if PRT (bit1 of parameter 6001) is 1. If parameter PRT is 0, a space
code is output each time a zero is encountered.
When the number of decimal places is not zero, digits in the decimal
part are always output. If the number of decimal places is zero, no
decimal point is output.
When PRT (bit 1 of parameter 6001) is 0, a space code is output to
indicate a positive number instead of +; if parameter PRT is 1, no
code is output.

Never specify the output device FANUC Cassette or Floppy for punching.
When specifying a DPRNT command to output data, specify whether
leading zeros are output as spaces (by setting PRT (bit 1 of parameter
6001) to 1 or 0).
To indicate the end of a line of data in ISO code, specify whether to use
only an LF (CRO, of bit 4 of parameter 6001 is 0) or an LF and CR (CRO
of bit 4 of parameter 6001 is 1).

NOTE
1
It is not necessary to always specify the open command
(POPEN), data output command (BPRNT, DPRNT), and
close command
(PCLOS) together. Once an open
command is specified at the beginning of a program, it does
not need to be specified again except after a close
command was specified.
2
Be sure to specify open commands and close commands
in pairs. Specify the close command at the end of the
program. However, do not specify a close command if no
open command has been specified.
3
When a reset operation is performed while commands are
being output by a data output command, output is stopped
and subsequent data is erased. Therefore, when a reset
operation is performed by a code such as M30 at the end
of a program that performs data output, specify a close
command at the end of the program so that processing such
as M30 is not performed until all data is output.

Explanations
Use of the interruption type custom macro function allows the user to call
a program during execution of an arbitrary block of another program.
This allows programs to be operated to match situations which vary from
time to time.
(1) When a tool abnormality is detected, processing to handle the
abnormality is started by an external signal.
(2) A sequence of machining operations is interrupted by another
machining operation without the cancellation of the current operation.
(3) At regular intervals, information on current machining is read.

Explanations
D Interrupt conditions
A custom macro interrupt is available only during program execution. It
is enabled under the following conditions
- When memory operation or MDI operation is selected
- When STL (start lamp) is on
- When a custom macro interrupt is not currently being processed
D Specification
Generally, the custom macro interrupt function is used by specifying M96
to enable the interrupt signal (UINT) and M97 to disable the signal.
Once M96 is specified, a custom macro interrupt can be initiated by the
input of the interrupt signal (UINT) until M97 is specified or the NC is
reset. After M97 is specified or the NC is reset, no custom macro
interrupts are initiated even when the interrupt signal (UINT) is input. The
interrupt signal (UINT) is ignored until another M96 command is specified.

When UINT is kept on
The interrupt signal (UINT) becomes valid after M96 is specified. Even
when the signal is input in M97 mode, it is ignored. When the signal input
in M97 mode is kept on until M96 is specified, a custom macro interrupt
is initiated as soon as M96 is specified (only when the status-triggered
scheme is employed); when the edge-triggered scheme is employed, the
custom macro interrupt is not initiated even when M96 is specified.

Details of Functions
Explanations
D Subprogram-type
There are two types of custom macro interrupts: Subprogram-type
interrupt and macro-type
interrupts and macro-type interrupts. The interrupt type used is selected
interrupt
by MSB (bit 5 of parameter 6003).
(a) Subprogram-type interrupt
An interrupt program is called as a subprogram. This means that the
levels of local variables remain unchanged before and after the interrupt.
This interrupt is not included in the nesting level of subprogram calls.
(b) Macro-type interrupt
An interrupt program is called as a custom macro. This means that the
levels of local variables change before and after the interrupt. The
interrupt is not included in the nesting level of custom macro calls. When
a subprogram call or a custom macro call is performed within the interrupt
program, this call is included in the nesting level of subprogram calls or
custom macro calls. Arguments cannot be passed from the current
program even when the custom macro interrupt is a macro-type interrupt.
D M codes for custom
In general, custom macro interrupts are controlled by M96 and M97.
macro interrupt control
However, these M codes, may already being used for other purposes (such
as an M function or macro M code call) by some machine tool builders.
For this reason, MPR (bit 4 of parameter 6003) is provided to set M codes
for custom macro interrupt control.
When specifying this parameter to use the custom macro interrupt control
M codes set by parameters, set parameters 6033 and 6034 as follows:
Set the M code to enable custom macro interrupts in parameter 6033, and
set the M code to disable custom macro interrupts in parameter 6034.
When specifying that parameter-set M codes are not used, M96 and M97
are used as the custom macro control M codes regardless of the settings
of parameters 6033 and 6034.
The M codes used for custom macro interrupt control are processed
internally (they are not output to external units). However, in terms of
program compatibility, it is undesirable to use M codes other than M96
and M97 to control custom macro interrupts.
D Custom macro interrupts
When performing a custom macro interrupt, the user may want to
and NC statements
interrupt the NC statement being executed, or the user may not want to
perform the interrupt until the execution of the current block is completed.
MIN (bit 2 of parameter 6003)is used to select whether to perform
interrupts even in the middle of a block or to wait until the end of the
block.
Type I
(i) When the interrupt signal (UINT) is input, any movement or dwell

(ii) If there are NC statements in the interrupt program, the command in
the interrupted block is lost and the NC statement in the interrupt
program is executed. When control is returned to the interrupted
program, the program is restarted from the next block after the
interrupted block.

macro interrupt signal
invalid when execution starts of a block that contains M97.
While an interrupt program is being executed, the interrupt signal
becomes invalid. The signal become valid when the execution of the
block that immediately follows the interrupted block in the main program
is started after control returns from the interrupt program. In type I, if the
interrupt program consists of only macro statements, the interrupt signal
becomes valid when execution of the interrupted block is started after
control returns from the interrupt program.
D Custom macro interrupt
during execution of a
block that involves cycle
operation
For type I
Even when cycle operation is in progress, movement is interrupted, and
the interrupt program is executed. If the interrupt program contains no
NC statements, the cycle operation is restarted after control is returned to
the interrupted program. If there are NC statements, the remaining
operations in the interrupted cycle are discarded, and the next block is
executed.
For type II
When the last movement of the cycle operation is started, macro
statements in the interrupt program are executed unless an NC statement
is encountered. NC statements are executed after cycle operation is
completed.

PROGRAMMING
15. CUSTOM MACRO
B-63534EN/02
D Custom macro interrupt
There are two schemes for custom macro interrupt signal (UINT) input:
signal (UINT)
The status-triggered scheme and edge- triggered scheme. When the
status-triggered scheme is used, the signal is valid when it is on. When
the edge triggered scheme is used, the signal becomes valid on the rising
edge when it switches from off to on status.
One of the two schemes is selected with TSE (bit 3 of parameter 6003).
When the status-triggered scheme is selected by this parameter, a custom
macro interrupt is generated if the interrupt signal (UINT) is on at the time
the signal becomes valid. By keeping the interrupt signal (UINT) on, the
interrupt program can be executed repeatedly.
When the edge-triggered scheme is selected, the interrupt signal (UINT)
becomes valid only on its rising edge. Therefore, the interrupt program
is executed only momentarily (in cases when the program consists of only
macro statements). When the status-triggered scheme is inappropriate,
or when a custom macro interrupt is to be performed just once for the
entire program (in this case, the interrupt signal may be kept on), the
edge-triggered scheme is useful.
Except for the specific applications mentioned above, use of either
scheme results in the same effects. The time from signal input until a
custom macro interrupt is executed does not vary between the two
schemes.

program, specify M99. A sequence number in the interrupted program
can also be specified using address P. If this is specified, the program is
searched from the beginning for the specified sequence number. Control
is returned to the first sequence number found.
When a custom macro interrupt program is being executed, no interrupts
are generated. To enable another interrupt, execute M99. When M99 is
specified alone, it is executed before the preceding commands terminate.
Therefore, a custom macro interrupt is enabled for the last command of
the interrupt program. If this is inconvenient, custom macro interrupts
should be controlled by specifying M96 and M97 in the program.
When a custom macro interrupt is being executed, no other custom macro
interrupts are generated; when an interrupt is generated, additional
interrupts are inhibited automatically. Executing M99 makes it possible
for another custom macro interrupt to occur. M99 specified alone in a
block is executed before the previous block terminates. In the following
example, an interrupt is enabled for the Gxx block of O1234. When the
signal is input, O1234 is executed again. O5678 is controlled by M96 and
M97. In this case, an interrupt is not enabled for O5678 (enabled after
control is returned to O1000).

NOTE
When an M99 block consists only of address O, N, P, L, or
M, this block is regarded as belonging to the previous block
in the program. Therefore, a single-block stop does not
occur for this block. In terms of programming, the following
and
are basically the same.
(The difference is
whether Gff is executed before M99 is recognized.)

D Custom macro interrupt
A custom macro interrupt is different from a normal program call. It is
and modal information
initiated by an interrupt signal (UINT) during program execution. In
general, any modifications of modal information made by the interrupt
program should not affect the interrupted program.
For this reason, even when modal information is modified by the interrupt
program, the modal information before the interrupt is restored when
control is returned to the interrupted program by M99.
When control is returned from the interrupt program to the interrupted
program by M99 Pxxxx, modal information can again be controlled by
the program. In this case, the new continuous information modified by
the interrupt program is passed to the interrupted program. Restoration of
the old modal information present before the interrupt is not desirable.
This is because after control is returned, some programs may operate
differently depending on the modal information present before the
interrupt. In this case, the following measures are applicable:
(1) The interrupt program provides modal information to be used after
control is returned to the interrupted program.

D Custom macro interrupt
When the interrupt signal (UINT) is input and an interrupt program is
and custom macro
called, the custom macro modal call is canceled (G67). However, when
modal call
G66 is specified in the interrupt program, the custom macro modal call
becomes valid. When control is returned from the interrupt program by
M99, the modal call is restored to the state it was in before the interrupt
was generated. When control is returned by M99Pxxxx;, the modal call
in the interrupt program remains valid.
D Custom macro interrupt
When the interrupt signal (UINT) is input while a return operation is being
and program restart
performed in the dry run mode after the search operation for program
restart, the interrupt program is called after restart operation terminates
for all axes. This means that interrupt type II is used regardless of the
parameter setting.

PATTERN DATA INPUT FUNCTION
16
This function enables users to perform programming simply by extracting
numeric data (pattern data) from a drawing and specifying the numerical
values from the MDI panel.
This eliminates the need for programming using an existing NC language.
With the aid of this function, a machine tool builder can prepare the
program of a hole machining cycle (such as a boring cycle or tapping
cycle) using the custom macro function, and can store it into the program
memory.
This cycle is assigned pattern names, such as BOR1, TAP3, and DRL2.
An operator can select a pattern from the menu of pattern names displayed
on the screen.
Data (pattern data) which is to be specified by the operator should be
created in advance with variables in a drilling cycle.
The operator can identify these variables using names such as DEPTH,
RETURN RELIEF, FEED, MATERIAL or other pattern data names. The
operator assigns values (pattern data) to these names.
