such as the Handy File.

The following types of data can be entered and output :

1. Program

2. Offset data

3. Parameter

4. Pitch error compensation data

5. Custom macro common variable

Before an input/output device can be used, the input/output related

parameters must be set.

OPERATION

8. DATA INPUT/OUTPUT

Of the external input/output devices, the FANUC Handy File use floppy

8.1

disks as their input/output medium.

FILES

In this manual, an input/output medium is generally referred to as a

floppy.

Unlike an NC tape, a floppy allows the user to freely choose from several

types of data stored on one medium on a file-by-file basis.

Input/output is possible with data extending over more than one floppy

disk.

Explanations

What is a File

The unit of data, which is input/output between the floppy and the CNC

by one input/output operation (pressing the VREADW or VPUNCHW

key), is called a HfileI. When inputting CNC programs from, or

outputting them to the floppy, for example, one or all programs within the

CNC memory are handled as one file.

Files are assigned automatically file numbers 1, 2, 3, 4 and so on, with the

lead file as 1.

File 1

File 2

File 3

File n

Blank

Request for floppy

When one file has been entered over two floppies, LEDs on the adaptor

replacement

flash alternately on completion of data input/output between the first

floppy and the CNC, prompting floppy replacement. In this case, take the

first floppy out of the adaptor and insert a second floppy in its place. Then,

data input/output will continue automatically.

Floppy replacement is prompted when the second floppy and later is

required during file search-out, data input/output between the CNC and

the floppy, or file deletion.

tion of file k

Since floppy replacement is processed by the input/output device, no

special operation is required. The CNC will interrupt data input/output

operation until the next floppy is inserted into the adaptor.

When reset operation is applied to the CNC during a request for floppy

replacement, the CNC is not reset at once, but reset after the floppy has

been replaced.

D Writing memo

Once written in the cassette or card, data can subsequently be read out by

correspondence between the data contents and file numbers. This

correspondence cannot be verified, unless the data contents and file

numbers are output to the CNC and displayed. The data contents can be

displayed with display function for directory of floppy disk (See Section

III-8.8).

To display the contents,write the file numbers and the contents on the

memo column which is the back of floppy.

designation of N1,N1 to 9999, or N*9999 or reset.

Press soft keys [FSRH] and [EXEC]

The specified file is searched for.

Explanations

D File search by N-9999

The same result is obtained both by sequentially searching the files by

specifying Nos. N1 to N9999 and by first searching one of N1 to N9999

and then using the N-9999 searching method. The searching time is

shorter in the latter case.

the program. When no program number is specified here, the

program number used on the floppy or NC tape is assigned.

Press soft keys [READ] and [EXEC]

The program is input and the program number specified in step 7 is

assigned to the program.

Explanations

D Collation

If a program is input while the data protect key on the machine operator’s

panel turns ON, the program loaded into the memory is verified against

the contents of the floppy or NC tape.

If a mismatch is found during collation, the collation is terminated with

an P/S alarm (No. 79).

If the operation above is performed with the data protection key turns

OFF, collation is not performed, but programs are registered in memory.

NC tape

S The O-number of the program on the NC tape is assigned to the

program. If the program has no O-number, the N-number in the first

block is assigned to the program.

S When the program has neither an O-number nor N-number, the

previous program number is incremented by one and the result is

assigned to the program.

S When the program does not have an O-number but has a five-digit

sequence number at the start of the program, the lower four digits of

the sequence number are used as the program number. If the lower four

digits are zeros, the previously registered program number is

incremented by one and the result is assigned to the program.

S When a program is entered with a program number

The O-number on the NC tape is ignored and the specified number is

assigned to the program. When the program is followed by additional

programs, the first additional program is given the program number.

Additional program numbers are calculated by adding one to the last

program.

D Program registration in

The method of registration operation is the same as the method of

the background

foreground operation. However, this operation registers a program in the

background editing area. As with edit operation, the operations described

below are required at the end to register a program in foreground program

memory.

D Outputting a program

When program output is conducted after N1 to N9999 head searching, the

after file heading

new file is output as the designated n-th position. In this case, 1 to n-1

files are effective, but the files after the old n-th one are deleted. If an

alarm occurs during output, only the 1 to n-1 files are restored.

D Efficient use of memory

To efficiently use the memory in the cassette or card, output the program

by setting parameter NFD (No. 0101#7, No. 0111#7 or 0121#7) to 1. This

parameter makes the feed is not output, utilizing the memory efficiently.
