The magnification is determined as shown below according to
the setting unit of the reference axis (specified by parameter
No.1031) and bit 0 (AUX) of parameter No.3405.

CAUTION

If a decimal fraction remains after multiplying the
specified value with a decimal point by a magnitude
in Table 11.4 (a), the fraction is truncated.

Example:

Specified value Output value
B0.12345

1234 (When inch input is used,
the reference axis is IS-B, and
parameter AUX is set to 1. The
magnification is 10000.)

NOTE

If the number of digits of the specified value
exceeds the allowable number of digits (set by
parameter No.3033), alarm PS0003 is issued.

When the specified value is multiplied by a
magnitude in Table 11.4 (a), the allowable number
of digits must be set for the resultant value.

Limitation

Addresses used for the second auxiliary functions (addresses specified
with B or parameter No. 3460) cannot be used as the addresses used
for controlled axis names.

12.1

FOLDERS

Overview

Folders can be created in program memory.

12.1.1

Folder Configuration

The following folders can be created:

•

Folder names are up to 32 characters long.

•

The following characters can be used in folder names:
Alphabetical characters (uppercase and lowercase letters),
numeric characters, and the symbols below:

−

_ .

Because "." and ".." are reserved folder names, they cannot be
used.

- Initial folders

When program memory is initialized, folders having predefined
structures and names are created. These folders are called initial
folders.

(1) Root

folder

The parent folder of all folders

(2) System

folder

(

SYSTEM

)

Contains subprograms and macro programs of the system.

(3) MTB dedicated folder 1 (MTB1)

Contains subprograms and macro programs created by the
machine tool builder.

(4) MTB dedicated folder 2 (MTB2)

Contains subprograms and macro programs created by the
machine tool builder.

(5) User

folder

Contains programs created by the user.
The following folders are further created in this folder:
(a) Path folders (PATHn: As many folders as the number of

paths are created.)
Each contains main programs, subprograms, and macro
programs used for the corresponding path.

(b) Common program folder (LIBRARY)

Contains subprograms and macro programs used
commonly.

NOTE

The initial folders can neither be deleted nor
renamed.

- User created folders

Folders other than the initial folders are called user created folders.
User created folders can be created in the following initial folders:

•

User

folder

•

Path

folders

User created folders can contain user created main programs,
subprograms, and macro programs.

NOTE

1 Folder names must each be unique in the same

folder.

2 Each time a user created folder is created, the

number of programs that can be registered
decreases by one.

3 Folder hierarchical levels of user created folders

are limited.
Up to three hierarchical levels starting from the
user folder (USER/) are permitted.

Folder Attributes

The following attributes can be set for folders except the root folder:

•

Edit

disable

•

Edit/display

disable

- Edit disable

Editing of the programs and folders in a folder can be disabled.
A program in the folder can be output to an external device.
A program cannot be input (registered) from an external device to the
folder.

- Edit/display disable

Editing and display of the programs and folders in a folder can be
disabled.
When this attribute is set for a folder, the programs and folders in the
folder become invisible. (The folder appears to contain nothing.)
A program in the folder cannot be output to an external device and a
program cannot be input (registered) from an external device to a
folder.

12.1.3

Default Folders

Default folders are folders on which operations are performed when
no folder is specified. There are two types of default folders as
follows:

•

Foreground default folder

•

Background default folder

- Foreground default folder

A folder used for foreground operations except automatic operations
and program editing is set.
The target operations include:

•

Program

input/output

•

External data input

•

External workpiece number search

- Background default folder

A folder used for background operations is set.
The target operations include:

•

Program

input/output

•

External I/O device control

NOTE

1 When the foreground or background default folder

is not set, a path folder, which is an initial folder, is
assumed.

2 Foreground and background default folder settings

are stored in default folder setting files.

3 When a program file, program folder, or program

folder management file is cleared, the default folder
setting file is cleared at the same time.

FILES

Overview

Desired file names can be given to part programs in program memory.

12.2.1

File Name

File names can be set as follows:

•

File names are up to 32 characters long.

•

The following characters can be used in file names:
Alphabetical characters (uppercase and lowercase letters),
numeric characters, and the symbols below:

−

_ .

Because "." and ".." are reserved file names, they cannot be used.

- File names and program numbers

File names are associated with program numbers as explained below.
When the file name of a program consists of "O" plus a numeric with
the following limitation, the program can be handled also by program
number.

•

The numeric must be a leading zero suppressed value from 1 to
9999.

When the file name of a program does not have the above format, the
program cannot be handled by program number.
When a file name consisting of "O" plus a numeric does not satisfy the
above limitation, the file cannot be created.

NOTE

1 File names must each be unique in the same

2 When the file name of a program is not treated as a

program number, the program is restricted as
follows:

- The program cannot be specified by program

number.

- Information output by program number is

impossible..
