NC FUNCTION
315
A data protection key can be installed on the machine side for protection
of various NC data. The following three input signals are offered,
according to type of data to be protected.
KEY 1
Allows input of tool compensation amount and work zero point offset
amount.
KEY 2
Allows setting data input and macro variable input.
KEY 3
Allows part program input and editing.
This function displays a history of the key and signal operations,
performed by the operator, upon the occurrence of a failure or alarm. The
history can also be displayed for previously generated alarms.
The following history data is recorded :
MDI key/soft key operation sequences
Example : A to Z, <POS>, <PAGE↑>, [SF1]
On/off status transitions of selected input and output signals
Example : G0000.7↑, SBK↑
NC alarm information
Example : P/S0010
Time (date, time) stamp
Example : 97/09/25
09:27:55
The history data can be output to an input/output device, connected via
the reader/punch interface. Previously output history data can be input
from an input/output device.
When a machining program is executed, the machining time of the main
program is displayed on the program machining time display screen. The
machining times of up to ten main programs are displayed in
hour/minutes/seconds. When more than ten programs are executed, data
for the oldest programs is discarded.
