RELATION WITH CONVENTIONAL FUNCTIONS

This section explains relation with conventional functions when folder
names and file names are used.

12.3.1

Relation with Folders

This subsection explains how folders are used for operations and
editing.

- Automatic operation
Main

program

As the main program running for an automatic operation, a program in
a desired folder can be selected.

Subprogram (called by M98/G72.1/G72.2)
Macro program (called by G65/G66/G66.1/M96)

•

Subprogram call (M98)

•

Macro call (simple call G65/modal call G66, G66.1)

•

Macro interrupt (M96)

•

Figure copying (G72.1, G72.2)

When a call listed above is made, folders are searched in the following
order, and the program found first is called:
<1> Folders containing the main program
<2> Common program folder, which is an initial folder (LIBRARY)

Bit 7 (SCF) of parameter No. 3457 can be used to add the following
search folders.    (The folders are searched in the order listed below.)
The folder to be actually enabled is separately set by bits 1 to 3 of
parameters No. 3457.
<3>  MTB dedicated folder 2, which is an initial folder (MTB2)
<4>  MTB dedicated folder 1, which is an initial folder (MTB1)
<5>  System folder, which is an initial folder (SYSTEM)

Subprogram (called by M code/specific address/2nd auxiliary function)
Macro program (called by G code/M code/T code/one touch macro)

•

Subprogram call by M code/specific address/2nd auxiliary

function code

•

Macro call by G code/M code/T code

•

One touch macro call

For programs called as listed above, the folders to be searched are set
in bits 0 to 3 of parameter No.3457 in advance.    (The search order is
described below.)
The folders set as the search targets are searched, and the program
found first is called.
<1>  Common program folder, which is an initial folder (LIBRARY)
<2>  MTB dedicated folder 2, which is an initial folder (MTB2)
<3>  MTB dedicated folder 1, which is an initial folder (MTB1)
<4>  System folder, which is an initial folder (SYSTEM)

- Program editing

A program in any folder can be edited.

- Program I/O

The following functions are performed for default folders:

•

Program input from external devices

•

Program output to external devices

(Except the format with folder names)

The following functions are performed for a set background default
folder:

•

External I/O device control

- External data input

A set foreground default folder is searched for an external program.

- External workpiece number search

A set foreground default folder is searched for an external workpiece
number.

- Macro executor

Programs called by execution macros, conversational macros, and
auxiliary macros are programs in P-Code files regardless of the default
folder.
For programs on the macro executor, the folder function and file name
function are unavailable.

12.3.2

Relation with File Names

File names can be used with the following functions:

•

Subprogram call (M98)

•

Macro call (simple call G65/modal call G66, G66.1)

•

Interruption type macro call (M96)

•

Subprogram call in figure copying (G72.1, G72.2)

•

Program I/O with external devices

NOTE

1 When characters in <> are read, they are treated in

the same way as for characters in comments. So,
note that these characters are treated differently
from other significant information portions.

Refer to Appendix B “PROGRAM CODE LIST” for
details.

2 The <file-name> word must be placed immediately

after each word for calling (M98, G65, and so forth).

NOTE

1 Creating one folder results in the number of

programs yet to be registerable decreasing one.

2 The program storage size means the maximum

size of a program if the program is the one and
only program registered.

3 If more than one program is registered, the total

size of registerable programs reduces for the
following reason.
The Series 30

/31

/32

-A and Series 31

-A5

manage programs in page units.    The unit of
program storage is managed also in page units.
When a program is created, as many pages as
necessary to store the program are secured, and
the program is stored on these pages. Generally,
the last program storage page has an unused area
(left figure).    This unused area cannot be used to
store any other program.    For the sake of program
management, it is regarded as an area in use.
The Series 16

/18

uses a similar way of

management, but the unit of pages in it differs from
that in the Series 30

PROGRAM CONFIGURATION

Overview
- Main program and subprogram

There are two program types, main program and subprogram.
Normally, the CNC operates according to the main program.
However, when a command calling a subprogram is encountered in
the main program, control is passed to the subprogram. When a
command specifying a return to the main program is encountered in a
subprogram, control is returned to the main program.

Follow the direction of the

Fig. 13 (a) Main program and Subprogram

The CNC memory can hold up to 4000 main programs and
subprograms (63 as standard). A main program can be selected from
the stored main programs to operate the machine. See III-9 or III-10.4
for the methods of registering and selecting programs.
