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.

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.

D Constant values that can

Explanations

Specify these commands in the following order:

Open command: POPEN

Before specifying a sequence of data output commands, specify this

command to establish a connection to an external input/output device.

Data output command: BPRNT or DPRNT

Specify necessary data output.

Close command: PCLOS

When all data output commands have completed, specify PCLOS to

release a connection to an external input/output device.

D Open command POPEN

POPEN

POPEN establishes a connection to an external input/output device. It

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.

Specify the channel use for setting data (I/O channel). According to the

specification of this data, set data items (such as the baud rate) for the

reader/punch interface.

I/O channel 0 : Parameters (No.101, No.102 and No.103)

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).

15. CUSTOM MACRO

NOTE

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.

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.

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.

Abbreviated macro words enclosed in brackets [ ] remains

unchanged. However, note that when the characters in

brackets are divided and input several times, the second

and subsequent abbreviations are converted and input.

O can be specified in brackets [ ]. Note that when the

characters in brackets [ ] are divided and input several

times, O is omitted in the second and subsequent inputs.

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.

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.

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

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.

B-64124EN/01

PROGRAMMING

15. CUSTOM MACRO

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.

15. CUSTOM MACRO

PROGRAMMING

B-64124EN/01

D Return from a custom

To return control from a custom macro interrupt to the interrupted

macro interrupt

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).

When an M99 block consists only of address O, N, P, L, or

in the program. Therefore, a single-block stop does not

occur for this block. In terms of programming, the following

and

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.

359

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.

FUNCTION

PROGRAMMING

B-64124EN/01

PATTERN DATA INPUT FUNCTION

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.
