5.6 Absolute value system 
5.6.1 Absolute system setting 
In order to save the position data of absolute encoder, the battery unit needs to be installed. 
Install the battery on the battery unit of the encoder cable with the battery unit. 
If you do not use encoder cable with battery unit, please set P-79 to 1, that is, multi-loop absolute value 
encoder is used as incremental encoder.

Normally use absolute encoder and use battery 
to memorize position. 
Use  multi-loop  absolute  encoder  as 
incremental encoder and no longer remember 
position 
Use as absolute encoder, ignore the multi-loop 
overflow alarm 
 
5.6.2 Replace the battery 
When replacing the battery, please replace the battery while keeping the driver and motor connected 
well and the control power is connected. If the battery is replaced when the control power between the 
driver and the motor is closed, the data stored in the encoder will be lost. 
 
Note: Absolute Encoder Battery Model (This Battery Can't Charge) 
Battery unit for normal cable:CP-B-BATT 
Battery unit for tank chain cable: CPT-B-BATT 
 
Battery replacement steps 
When using encoder cable with battery unit 
(1) Only the control power of the servo unit is connected; 
(2) Open the cover of the battery cell; 
 
(3) Take out the old battery, install the new one.
