Note:
To avoid data loss, replace the battery when any of the following circumstances occurs: 1. The servo drive
shows AL061 which means the voltage is too low. Refer to Chapter 13 for more information. 2. Use P0.002
(monitoring variable 26h) to check the battery power. When it displays 31, it means the voltage is under 3.1V.
When the voltage is under 2.45V, the motor's position record may be lost if the drive operates under battery
power, so you need to re-establish the absolute origin coordinates after installing a new battery. Thus, it is
suggested that you replace the battery when the main power to the servo drive is on.
