9.2.6 Notes for Maintenance
Battery Pack Connections
The connectors (crimped contact-pin) for the battery backup are installed at the end point of
the motors (BAT and OBT are marked). Connect the battery packs according to the following
procedure.
1. Remove the caps attached to the battery backup connectors of the motors.
2. Connect battery packs (HW9470932-A) to the battery backup connectors (BAT and
OBT are marked) located at the end point of the cables for the encoder. (Remove the
encoder connector and carry out maintenance checks with the battery packs con-
nected to the battery backup connectors.)
3. Confirm all connectors are connected after the maintenance checks, and remove the
battery packs. Reinstall the caps onto the battery backup connectors of the motors.
Fig. 29 Battery Pack Connection
When performing maintenance such as replacement of a wire harness in the manipulator,
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.
Removing the encoder connector without connecting the battery pack leads to disappear-
ance of the encoder absolute data.
For the battery pack connection, refer to " Fig. 29 Battery Pack Connection ".
Do not remove battery packs in the connector base.
