Depress the

key.

Then up to four pairs of alarm code and mes-

sage will be displayed, with more serious one
on a higher line.

Note : The alarm screen will appear during an alarm

state and therefore, depressing the

‘AGE key is not

necessary.

For more detail of this operation, see 7.6.3,

SIGNALS’.

The state of the input/output signal is also
given in the hexadecimal notation at the right-

most column for the ease of maintenance work.

Such NC data as tool offsets, setting data, and para-
meter data can be read from and written onto tape. A
tape reader can work to read data from tape. To write
data onto tape, a data input/output interface (option)
is needed.

Here we assume that this option is incorporated.

See Par. 4.7.2 for how to set the type of input/out-
put device (setting #6003) and baud rate (parameter
#6026).

4.4.1 INPUTTING TOOL OFFSETS FROM TAPE

Though tool offsets are normally input by MDI oper-

ation, they can also be entered by means of paper
tape.

The tape format of tool offsets is as follows.

1.000 ;

H02 X

2.000 ;

D03 x-10. O89 ;

Note :
Either H or D can
be used for address.

The input operation is as follows

A .

Select EDIT mode.

Depress the RESET key.

Depress the OFS key.

Set the tool offset data tape onto the tape
reader.

Depress the IN key.

The tape reader starts reading the tape.

“

”

while the data are read.

The tape reader stops when it has read

(or ER)

and “IN disappears from the CRT.
Now the tool offset data have been read into
memory.
