9.3.6.1 Battery Pack Connection for Motors
The connectors (crimped contact-pin) for battery backup are installed at
the end point of each motor (marked as BAT and OBT). Connect the
battery pack according to the following procedure.
1. Remove a cap attached to battery backup connectors of the motor.
2. Connect a battery pack (HW9470932-A) to the battery backup
connectors (BAT and OBT are marked) located at the end point of an
encoder cable. With the battery pack connected to the battery backup
connectors, perform maintenance check.
3. After the maintenance check, confirm all connectors are connected
and remove the battery pack. Reinstall the cap onto the battery
backup connectors of the motor.

NOTE
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 disappearance of the encoder
absolute data.
For the battery pack connection, refer to
.
NOTE
Do not remove battery pack in the connector base.
