(1) Operation mode
"Operation mode" of CPU is set by the state of DIP switch 2, 3, 5 of Motion CPU
module at the power supply on or reset of Multiple CPU system.
DIP switch setting, operation mode and operation mode overview are shown
below.

(b) Operation mode overview
• MODE LED turns on in orange.
• BOOT LED turns off.
• The operating system software can be installed.
• The user programs and parameters for ROM operation can be written to the FLASH ROM built-
in Motion CPU module.
• ROM writing is executed at ROM operating after operation check in the RAM operating mode.
The user programs and parameters stored in the SRAM built-in Motion CPU module are batch
written to the FLASH ROM built-in Motion CPU module.
• It becomes STOP state regardless of the RUN/STOP switch in front of Motion CPU module.
• The digital oscilloscope function cannot be used.
• MODE LED turns on in green.
• BOOT LED turns off.
• Operation is executed based on the user programs and parameters stored in the SRAM built-in
Motion CPU module.
• MODE LED turns on in green.
• BOOT LED turns on.
• Operation starts after reading the user programs and parameters stored in the internal FLASH
ROM to the internal SRAM at power supply on or reset of Multiple CPU system.
Even if the user programs and parameters are changed by SW6RN-GSV43P during ROM
operating mode, it returns to the contents of internal FLASH ROM at next power supply on or
system reset.
Also, even if the auto tuning data are reflected on the servo parameter of Motion CPU by
operating the servo amplifier with auto-tuning setting, it returns to the contents of internal
FLASH ROM at next power supply on or reset release.
