Notes for Maintenance
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
.
9.4.1 Battery Pack Connection
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 cap attached to the battery backup connector of the
motors.
2. Connect the battery packs (HW9470932-A) with the battery backup
connectors (BAT and OBT are marked) located at the end point of the
cables for the encoder. (Under this condition, remove the encoder
connector and carry out the maintenance checks.)
3. Confirm all connectors connected after the maintenance check, and
remove the battery packs. Install the caps attached to the battery
backup connectors of the motors.
