1.1 Battery Pack Connection for Motor

• 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 Fig. 1-1 "Battery
Pack Connection".
Battery Pack Connection for Motor
The connectors (crimped contact-pin) for the battery backup are installed
at the end point of the encoder cables for the motor (BAT and OBT are
marked).
Connect the battery pack according to the following procedure.
1. Remove the caps attached to the battery backup connectors of the
motor.
2. Connect the battery pack (HW9470932) with the battery backup
connectors located at the end point of the encoder cable. (Under this
condition, remove the encoder connector and carry out the
maintenance checks.)
3. After the maintenance check, confirm that all the connectors are
connected, then remove the battery pack. Install the caps attached to
the battery backup connectors of the motor.
Do not remove the battery pack in the connector base.
