4. Replacing the absolute battery
The absolute battery is a consumable part. If a sign of low battery (warning message) occurs, this is
determined as expiration of the battery service life, and replace the absolute battery.
Depending on the operating conditions, the reference for battery replacement is that the total power off time
after the battery has been connected to the controller reaches about 8,000 hours (about one year).
WARNING
To avoid danger, never replace the absolute battery in servo on status. Otherwise electrical shock, robot
abnormal operation or controller malfunction may occur.
NOTE
For details about how to replace the absolute battery, refer to "4. Connecting the absolute battery" in Chapter 3.
5. Replacing the memory battery
The memory battery is a consumable part. If a trouble occurs in the backup data retention, this is determined
as expiration of the battery service life, and replace the memory battery.
Depending on the operating conditions, the reference for battery replacement is that the total power off time
reaches about four years.
CAUTION
• If the memory battery is removed, the data files (program, point, point comment, parameter, shift, hand, and
pallet, etc.) saved inside the controller will be lost. Therefore, be sure to save the data into an external storage
device before performing the replacement work.
• After the battery replacement work has been completed, load the data that has been saved into the external
storage device into the controller.
• When replacing the memory battery, the robot is put in the return-to-origin incomplete status. Be sure to perform
return-to-origin after the battery replacement
