A (approx. 4 A if the main
controller power is on).
* To avoid breakdown, do not attempt to modify or extend the battery cable.
* The battery is always replaced together with the battery board. The battery cannot be replaced separately. Only
use the battery specified by IAI.
(2) Battery Alarm and Battery Error
Once the battery voltage has dropped to approx. 3.1 V, a battery alarm occurs (alarm code: 07A). This
alarm is output to PIO connector pin 7. The controller does not stop operating immediately upon occurrence
of a battery alarm. The alarm merely alerts the user that the battery must be replaced as soon as possible.
After a battery alarm occurs, the controller can still operate for approx. 220 hours (approx. 9 days) before a
battery error occurs.
To temporarily reset the battery alarm, input a reset signal or press the BEGIN/END key on the teaching
pendant for at least 2.5 seconds.
Note) The battery alarm function is supported on controllers of version H2 or later.
Once the battery voltage has dropped to approx. 2.5 V, a battery error occurs. This error (alarm code:
0E5) will be detected the next time the controller power is turned on. A battery error is detected only after
the controller power has been turned on.
The controller can no longer operate once a battery error occurs. You must replace the battery and
perform an absolute reset.
