Position No. 10001-20000 and user retained memory (RC-axis position in XSEL) are added to X-SEL-P/Q,
PX/QX controller with gateway function.
(Other parameter No. 20 = "0" (Backup battery not installed))
Programs, parameters and symbols are loaded from the flash memory after a restart. Unless written to the
flash memory, edited programs, parameters and symbols will return to the original data once the controller is
restarted.
The controller always operates according to the data (excluding parameters) stored in its memory (indicated
by dotted lines).
Note: SEL global data cannot be retained when a backup battery is not installed.
