INTELLIGENT ACTUATOR
Chapter 1 How to Save Data
Since the X-SEL Controller uses flash memory, some data are saved by battery backup while others are
saved in the flash memory.
When data is transferred from the PC software or teaching pendant to the controller, the data is only
written to the temporary memory and will be erased once the controller is powered down or reset.
For important data, always write to the flash memory so that they will not be lost.
1. Factory Settings: When the System-Memory Backup Battery is Used
(Other parameter No. 20 = 2 (System-memory backup battery installed))
* The encoder parameters are stored in the EEPROM of t KHDFWXDWRU¶VHQFRGHULWVHOIQRWLQWKHFRQWUROOHU
The encoder parameters will be read to the controller when the power is turned on or upon software
reset.
Data edited on the PC
or teaching pendant
Data will be retained while
the power is on and
cleared upon reset
Data will be retained even after the
power is turned off
