When the system is started in the normal way, the BOOT SYSTEM
automatically transfers files from flash ROM to DRAM, and the user need
not be concerned with the BOOT SYSTEM. If maintenance is to be
performed or if the flash ROM does not contain the necessary file, the
BOOT SYSTEM must be operated by displaying the appropriate menu.

keys, and turn on the power.
(2)“If flash ROM does not contain a file needed for the CNC to start”
As soon as the CNC is turned on, the BOOT SYSTEM starts
transferring files from flash ROM to DRAM. If flash ROM does not
contain the minimum file (NC BASIC) required for the CNC to start,
or if this file has been destroyed, CNC DATA SEARCH:ERROR is
displayed.
In this state, pressing the RESET
RESET
key causes the SYSTEM
MONITOR screen to appear.
The BOOT SYSTEM divides the files handled with flash ROM into two
main types, “system file” and “user file” and manages these two types of
files. The differences between the two types of files are as described
below:
Files containing FANUC–supplied software for controlling CNCs and
servos.
User–created files such as those containing PMC sequence programs
(ladder programs) and P–CODE macro programs
