14.20 Diagnosis Data Output

14.20.1 Outline

Diagnosis data output is a function designed to output the information on when to exchange the life-limited parts of the NC
and its peripherals.
The information, which is output to ZR registers, can be used for preventive maintenance, including lifetime prediction.

14.20.2 Function Details

The output data is automatically reset at the time of replacing the specific product (NC unit, drive or motor). (Note)
If you have replaced the part (battery, etc.) only, you can reset the data by writing 0 in the ZR register. After the reset, reboot
the NC.
Note
(1) To avoid any unintended reset at a tentative replacement, the control performs automatic reset upon the first NC startup
after 24 hours have passed after the replacement. Using the ZR register value, you can adjust the length of time from
replacement until data clear.
Table below shows the data items to be output.
The control outputs the information for each servo axis or spindle. The information of spindle C axis is output to the spindle's
ZR registers.
The information of a spindle-mode servo axis is also output to the spindle's ZR registers.
