5.2. Maintenance Item
5.2.1. Battery Replacement
The absolute encoder is used for position recording. When the power is
interrupted, the backup battery must be used to memorize the current position of
the encoder. The robot has been installed with the battery at the time of shipment.
Usually, the battery replacement time is about one year, but this varies depending on
the condition of the arm used. Users need to check regularly and replace before the
battery runs out. The following figure shows how to replace the battery of the robot
arm:
Step1. Confirm the wiring between the robot arm and the controller and turn on
the controller.
Step2. Press the emergency stop problem.
Step3. Open the battery cover. (Hexagon socket head screw, M3×0.5P×6L)
Step4. Replace four spare batteries one by one, the battery is 3.6V. If all the
batteries are removed at one time, the encoder data will be lost and the
robot must be recalibrated.
Step5. Put the battery cover back to robot.
Please make sure that all 4 batteries are new and avoid mixing old and new.
