Chapter 9 NC Control Function
Chapter 9 describes how the motion controller user creates the motion program of the G-code format.
The motion controller can program motions through a kind of scripting language called the G code. Chapter 9 describes
the basic terms and conceptual explanations for the G code programming, and explains how to configure the program. It
also describes the command scripts such as G, M, and F supported by the motion controller.
9.1 NC Command
9.1.1 Definition of the NC Command
The motion control is used by the user to move the machine from any position to the desired position at the
specified speed or to control the input / output. At this time, the axis that moves the machine will operate in various
ways depending on each control environment. It is the motion control program that is used to control the movement
of various axes, and in the motion controller, when the G code is used among the control information constituting the
motion control program this is called the NC command.
9.1.2 Definition of the Command Character
