■Save/restore configuration (Un\G22)
This area is used to save the buffer memory settings to the flash ROM or restore the factory default settings.
To enable this setting, turn on 'Configuration save/factory default configuration restore request' (Y1F). ( Page 153
Configuration save/factory default configuration restore completed/request (X1F)/(Y1F))
When the processing is finished, 'Save/restore configuration' (Un\G22.0) and 'Save/restore configuration' (Un\G22.1) will
automatically turn off, and 'Configuration save/factory default configuration restore completed' (X1F) will turn on.

*1 These areas are not save target in the CANopen 405 mode.
*2 These areas are not save target in the11-bit CAN-ID Layer 2 message mode or 29-bit CAN-ID Layer 2 message mode.
If both bits 'Save/restore configuration' (Un\G22.0) and 'Save/restore configuration' (Un\G22.1) are turned on
simultaneously, the buffer memory and flash ROM will be reset to factory default settings.
If only 'Save/restore configuration' (Un\G22.1) is turned on, the buffer memory settings will not be saved in the
flash ROM when reset to the factory default settings. Therefore, save the buffer memory settings in the flash
ROM in advance.
The settings saved with CANopen Configuration Tool have priority over the settings saved with this function.
Note that the object dictionary is not saved/restored with 'Save/restore configuration' (Un\G22). To save/
restore the object dictionary, use the following method.
• CANopen Configuration Tool ( Page 82 "CANopen Configuration" window, Page 84 "CANopen node
settings" window)
• Object dictionary (Page 207 Store parameters, Page 208 Restore default parameters)
