[2] Saving of data
XSEL controllers have areas saved by the backup battery and areas saved by the flash
memory.
Also note that even if you transfer data to your controller via the PC software or teaching
pendant, the data is only written to the temporary memories and will be cleared once the
power is turned OFF or controller is reset, as shown below.
So that your important data is saved without fail, write the data to the flash memory.
[System-memory backup battery is used]
Other parameter No. 20 = 2 (System-memory backup battery installed)
* Encoder parameters are stored not in the controller, but in the EEPROM of the actuator's encoder. Accordingly, they
are loaded to the controller when the power is turned on or software is reset.
Since programs, parameters and symbols are loaded from the flash memory upon restart,
these data in the temporary memories will return to the conditions before editing unless written
to the flash memory. The controller always operates according to the data in each temporary
memory (dotted box) (excluding parameters).
Content 1: Parameters other than those included in Content 2 below and encoder
parameters
Content 2: Driver card and I/O slot card (power card) parameters
Content 3: Flags, variables and strings
Data edited on the PC or
teaching pendant
Data is retained while
the power is ON,
but cleared upon reset
Data is retained even after
the power is turned OFF
