3.1.1 Backup Battery (Absolute Specification)
(1) Battery specifications
Item Description
Model number AB-1
Classification Lithium battery
Manufacturer Toshiba Battery (ER6VP)
Nominal voltage 3.6 V
Rated capacity 2000 mAh
Weight Approx. 8.5 g
Battery retention time Note 1) Approx. 20,000 hours (at surrounding air temperature of 20 C)
Note 1) The absolute-data backup battery consumers approx. 100 A during backup. (When the main controller
power is on, the current consumption is approx. 4 A.)
* Do not modify or extend the cable. It may result in controller failure.
* The battery is replaced together with the battery board. The battery cannot be replaced alone. Be sure to use
the battery module specified by IAI.
(2) Battery alarm and battery error
A battery alarm (alarm code: 07A) will occur when the battery voltage drops to approx. 3.1 V. This alarm is
output to PIO connector pin No. 15. The controller operation will not be disabled right away after a battery
alarm occurs. The alarm merely indicates that the battery should be replaced soon. Once a battery alarm
occurs, the controller will generate a battery error in approx. 220 hours (around nine days).
A battery alarm can be temporarily reset by inputting a reset signal or pressing the BEGIN/END key on
the teaching pendant for at least 2.5 seconds.
Note) The battery-alarm function is supported by the 100/200-V controller of version M5 or later.
A battery error will occur when the battery voltage drops to approx. 2.5 V. Once the battery voltage drops
to this level, the controller will detect an error (alarm code: 0E5) the next time the power is turned on. A
battery error is detected only when the controller power is turned on.
The controller operation will be disabled once a battery error occurs. You must replace the battery, and
then execute an absolute reset.
