When the tool exceeds a stored stroke limit, an alarm is displayed and the

tool is decelerated and stopped.

When the tool enters a forbidden area and an alarm is generated, the tool

can be moved in the reverse direction from which the tool came.

Explanation

D Stored stroke check 1

Parameters (Nos. 1320, 1321 or Nos. 1326, 1327) set boundary. Outside

the area of the set limits is a forbidden area. The machine tool builder

usually sets this area as the maximum stroke.

D Stored stroke check 2

Parameters (Nos. 1322, 1323) or commands set these boundaries. Inside

(G22, G23)

or outside the area of the limit can be set as the forbidden area. Parameter

OUT (No. 1300#0) selects either inside or outside as the forbidden area.

In case of program command a G22 command forbids the tool to enter the

forbidden area, and a G23 command permits the tool to enter the

forbidden area. Each of G22; and G23; should be commanded

independently of another commands in a block.

The command below creates or changes the forbidden area:

In stored stroke check 2, even if you mistake the order of the coordinate

value of the two points, a rectangular, with the two points being the

apexes, will be set as the area.

When you set the forbidden area through parameters (Nos. 1322, 1323),

the data should be specified by the distance from the machine coordinate

system in the least command increment. (Output increment)

If it is set by a G22 command, specify the data by the distance from the

machine coordinate system in the least input increment (Input increment.)

The programmed data are then converted into the numerical values in the

least command increment, and the values are set as the parameters.

The following types of data can be entered and output :

1.Program

8. DATA INPUT/OUTPUT

OPERATION

B-63534EN/02

8.1

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

disks as their input/output medium.

FILES

In this manual, these 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

D 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

D 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.

File n

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.

Procedure

1

Make sure the input device is ready for reading.

For the two-path control, select the tool post for which a program to

be input is used with the tool post selection switch.

2

Press the EDIT switch on the machine operator’s panel.

3

When using a floppy, search for the required file according to the

procedure in III-8.2.

4

Press function key

PROG

, then the program contents display screen or

program directory screen appears.

5

Press soft key [(OPRT)].

6

Press the rightmost soft key

(next-menu key).

7

After entering address O, specify a program number to be assigned to

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

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

8

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 alarm (P/S No. 079).

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

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

D Program numbers on a

• When a program is entered without specifying a program number.

NC tape

⋅

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.

⋅

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.

⋅

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.

• 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.

[(OPRT)] [BG-END]

D Additional program input

You can input a program to be appended to the end of a registered

program.

In the above example, all lines of program O5678 are appended to the end

of program O1234. In this case, program number O5678 is not registered.

When inputting a program to be appended to a registered program, press

the [READ] soft key without specifying a program number in step 8.

Then, press the [CHAIN] and [EXEC] soft keys.

S In entire program input, all lines of a program are appended, except for

its O number.

D File output location

When output is conducted to the floppy, the program is output as the new

file after the files existing in the floppy. New files are to be written from

the beginning with making the old files invalid, use the above output

operation after the N0 head searching.

D An alarm while a

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.

D On the memo record

Head searching with a file No. is necessary when a file output from the

CNC to the floppy is again input to the CNC memory or compared with

the content of the CNC memory. Therefore, immediately after a file is

output from the CNC to the floppy, record the file No. on the memo.
