Since the X-SEL Controller adopts flash memory, there is a storage area by battery backup and a
storage area by flash memory according to the data to be stored.
In addition, even if data is transferred from the PC software or Teaching Pendant, the data is only
to be written in memory as shown in the chart below and the data is erased by power-off or
controller reset.
To ensure data storage, write the data you want to store in flash memory.

* Encoder parameters are not stored within the controller but in the EEPROM of the actuator’s
encoder itself. They are read into the controller at power-on or software-reset time.

Since the program, parameter, and symbol will be read from flash memory at restart time, the
data in memory becomes the original data before editing unless the data is written in flash
memory.
The controller always operates according to the data in memory (within the dotted box) excluding
parameters.

Note: SEL global data can’t be saved without the backup battery.
