Part 3 Controller Data Structure
2. When the System Memory Backup Battery is Not Used
2.1 Controller without Increased Memory Size
Other parameter No. 20 = 0 (System memory backup battery not installed)
The programs, parameters, symbols and positions are read from the flash memory at restart. The data in
the main CPU memory will remain the same as the original data before edit unless the edited data are
written to the flash memory. The controller always operates in accordance with the data in the main CPU
memory (excluding the parameters).
Note: SEL global data cannot be retained if the backup battery is not installed.
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
