6.2.1 Backup Batteries Replacement
The absolute encoder of the motor is used to record the position of the robot. When the
controller power is turned off, the position data of each -axis is preserved by the backup batteries.
The batteries are installed when the robot is delivered from the factory. If the batteries are in use,
the annual change of batteries is needed. The service life of the batteries depends on the operating
conditions of the robot. In order to avoid the loss of position data, the batteries need to be
changed by the user periodically. The procedure for replacing the batteries of the robot is shown
in Figure 6-1 and described as below.
Step1.
Press the emergency stop button to prohibit the movement of the robot motion.
Step2.
Ensure the robot and controller are connected with the cables. Keep the power ON.
Step3.
Please remove the battery cover. The screws for battery cover are hexagon head screws
(M3×0.5P×6L) and the four batteries are 3.6V.
Step4.
Replace the battery one by one. If all batteries are removed at the same time, the
position data will be lost. If so, please reset the robot to the Zero-position. All batteries
should be changed one at a time.
Step5.
After replacing the battery, ensure to install the battery cover to prevent the robot being
damaged by dust and grease.
All batteries should be changed at one time. If the old
batteries are included, the service life of the batteries may
be reduced.
