5.3.5 Replacing the backup battery
An absolute encoder is used for the position detector, so the position must be saved with the backup battery
when the power is turned OFF. The controller also uses a backup battery to save the program, etc. These
batteries are installed when the robot is shipped from the factory, but as these are consumable parts, they must
be replaced periodically by the customer.
The guideline for replacing the battery is one year, but this will differ according to the robot's usage state.
Error No. 7520 :Battery consumption time is over
Error No. 133n :Encoder battery voltage low. (n indicates the axis number.)
(The encoder battery voltage of the robot arm is low.)
Error No. 7510 :Battery voltage low (R/C)
(The battery voltage of the controller is low.)
Error No. 7500 :No battery voltage
(The battery of the controller is depleted.)
If error No. 7500 occurs, the program data and other data in the controller is lost
and it becomes necessary to load the data again.
If any of the battery-related errors above occur and the robot continues to be used,
the data integrity of the memory cannot be guaranteed. If an error occurs, replace
the batteries of both the robot arm and controller promptly.
It is also recommended to save programs and position data on the personal
computer side via the personal computer support software and so forth in advance.
