Note on maintenance
NOTICE
The absolute encoder data will be lost.
Removing the encoder connector without connecting the battery pack results in the
disappearance of the encoder absolute data.
When performing maintenance such as replacement of a wire harness in the robot, the
encoder connector may be necessary to be removed. In this case, be sure to connect
the battery pack to the battery backup connector before removing the encoder
connector. The battery connectors are dealt with in the chapter 9.2.1 "Changing battery
unit"on page 56.
