CAUTION
Fig.5-14 ： Replacing the battery
1) Confirm that the robot arm and controller are connected with a cable.
2) Turn the controller control power ON.
The position data is retained by the power supplied from the controller while replacing the battery. Thus, if
the cable is not connected correctly, or if the controller power is OFF, the position data will be lost.
3) Press the emergency stop button to set the robot in the emergency stop state. This is a measure for safety,
and must always be carried out.
4) Remove the two installation screws (1), and remove the battery cover (2).
5) Remove the old battery from the holder, and disconnect the lead connector.
6) Insert the new battery into the holder, and connect the lead connector. Replace all batteries with new ones at
the same time.
7) Carry out steps 4) to 6) in reverse to install the parts.
8) Initialize the battery consumption time.
Always carry out this step after replacing the battery, and initialize the battery usage time. Refer to the sep -
arate "Instruction Manual/Detailed Explanation of Functions and Operations" for details on the operation
methods.
Don't disconnect connector, etc. While replacing the battery, the encoder position
data is saved by the power supplied from the controller. Thus, if the cable
connection is incomplete, the encoder position data will be lost when the controller
power is turned OFF. Several batteries are used in the robot arm, but replace all old
batteries with new batteries at the same time.
