FOREGROUND AND BACKGROUND
The NC has memory area to store programs.
The memory area is basically divided into two areas: the foreground area, for programs that
directly control the machine, and the background area, where the stored data cannot be used to
directly control the machine.

Register programs used for machining in the foreground area. A program stored in this area
cannot be edited during automatic operation.
2.
A program stored in the foreground area must be transferred to the background area so it
can be edited during automatic operation.
Program editing and program input/output to/from the background area are possible
regardless of the selected operation mode.
3.
A program input to or edited in the background area must be transferred to the foreground
area to be run.
