9. Connecting the absolute battery
The absolute batteries shipped with the controller are unused, and the battery connectors
are left disconnected to prevent discharge.
After installing the controller, always be sure to connect the absolute batteries before
connecting the robot cable.
Absolute batteries should be connected to the BATT XY/ZR connectors on the front right of the
controller.
The same absolute battery (or batteries) is shared by the X and Y axes or by the Z and R axes.
Connect the X and Y axis absolute battery to either of the two "BATT XY" connectors, and the Z and
R axis absolute battery to either of the two "BATT ZR" connectors.
When the batteries are connected to both connectors (standard connection), the data retention time
will be doubled compared to a single battery connection.
