Relationship with Other Functions

Relationship between the screen switching function and a return from the
alarm screen during switching between paths

(1) When bit 5 (PSC) of parameter No. 3208 is set to 0, if paths are

switched by the path switching signal or switching to the loader,
the screen last selected in the path appears again.
At this time, even if a return from the alarm screen to the
previous screen is performed in one path, a return is not
performed in the other path and the alarm screen remains
displayed.

(Example)

<1> When the message key is pressed on the offset screen of

path 1, the alarm screen (path 1) appears.

<2> When switching to path 2 is performed on the alarm screen

of path 1, the position screen of path 2 appears (when the
screen last displayed in path 2 is the position screen).

<3> When the message key is pressed on the position screen of

path 2, the alarm screen (path 2) appears.

<4> When the alarm is cleared or the message key is pressed on

the alarm screen of path 2, a return to the position screen
(path 2) is performed.

<5> When switching to path 1 is performed, the alarm screen

(path 1) appears.

(2) When PSC of parameter No. 3208 is set to 1, if paths are

switched by the path switching signal or switching to the loader,
the screen displayed immediately before the path switching
appears again.
At this time, if a return from the alarm screen to the previous
screen is performed in one path, the screen of the path in which a
return was performed appears in the other path.

The above types of data can be input and output on the screens for
displaying and setting those types of data.
If NC data such as programs and parameters is to be written to a
memory card, and if a file with the same name already exists, it is
possible to select whether to overwrite the existing file or cancel
writing with appropriate operation.
This function is enabled by setting bit 1 (COW) of parameter No.
11308.

The external I/O device set in NC parameter No. 0020 is selected. See
the table below for details.

NOTE

External I/O devices can handle file names of up to
12 characters each. NC programs on the memory
of the CNC can each be assigned any file name of
up to 32 characters, but the name is restricted to
up to 12 characters in the input/output to and from
external I/O devices.

OVERWRITING FILES ON A MEMORY CARD

Screen display

When an attempt is made to output NC data to a memory card, and if
the specified file name or the default file name is the same as an
existing file name on the memory card, a confirmation message
"OVERWRITE?" appears. (Bit 1 (COW) of parameter No. 11308 = 1)

Fig. 8.1 (a) Screen display example

Procedure

On the output screen for the desired function, perform the following
operation.
1

Press the soft key [PUNCH].

Press the soft key [EXEC]. If a file with the same name does not
exist on the memory card, the file is output in this step.

If a file with the same name exists on the memory card, soft keys
[REWRITE] and [CAN] appear.
Pressing the soft key [REWRITE] causes the file to be
overwritten.
Pressing the soft key [CAN] causes output to be canceled.

Example) Output from the parameter screen (for 7.2/8.4/10.4-inch

display unit)

Press the function key

Press the soft key [PARAMETER].

Enter the EDIT mode or state emergency stop.

Press the soft key [(OPRT)].

Press the soft key [PUNCH]. The soft key display switches from
the one in Fig. 8.1 (b) to the one in Fig. 8.1 (c).

Press the soft key [EXEC]. Because no file name is specified, the
file is output with a file name of CNC-PARA.TXT, but if a file
with the same name exists on the memory card, the soft key
display switches from the one in Fig. 8.1 (c) to the one in Fig. 8.1
(d), with a confirmation message appearing.
If a file with the same name does not exist on the memory card,
the file is output directly.

8 Pressing the soft key [REWRITE] causes the file to be

overwritten.
Pressing the soft key [CAN] causes output to be canceled. If
wishing to output the file after changing the file name, specify a
file name after step 6, and perform step 7 again.

Example) Output from the parameter screen (for 15-inch display

unit)

Press the function key

Press the vertical soft key [PARAMETER].

Enter the EDIT mode or state emergency stop.

Press the horizontal soft key [PUNCH]. The horizontal soft key
display switches from the one shown in Fig. 8.1 (e) to the one in
Fig. 8.1 (f).

Press the horizontal soft key [EXEC]. Because no file name is
specified, the file is output with a file name of CNC-PARA.TXT,
but if a file with the same name exists on the memory card, the
horizontal soft key display switches from the one in Fig. 8.1 (f)
to the one in Fig. 8.1 (g), with a confirmation message appearing.
If a file with the same name does not exist on the memory card,
the file is output directly.

Pressing the horizontal soft key [REWRITE] causes the file to be
overwritten.
Pressing the horizontal soft key [CAN] causes output to be
canceled. If wishing to output the file after changing the file
name, specify a file name after step 4, and perform step 5 again.

message "OVER WRITE FAILED" is issued and
output is canceled in the following cases:

- The file to be overwritten is for read only.
- The memory card is pulled out while the

confirmation message appears.
