8.10.6 BOOT-DIP-Switch
During a restart/reset, the BOOT-DIP-Switch is used to determine whether to perform a firmware download from the SD/MMC
card or not.
BOOT-DIP-Switch in position “ON”  firmware download requested
BOOT-DIP-Switch in position “OFF”  firmware download not requested
When there is no SD/MMC card in the card slot of the servo positioning controller and the BOOT-DIP-Switch is in the position
“ON” (firmware download requested), the error 29-0 is triggered after a restart/reset.
This error stops all further performances. This means that there is no communication possible via the serial interface (RS232)
or USB.
