The controllers may operate under both Local and/or Global mode. In general, operating in Global mode simplifies controlling the entire system. However, Local Mode operation is necessary in some situations; Using local mode for setup and testing is useful since this isolates the controller. Specific modes of motion require operation in Local Mode. Also, each controller can have a program, including the slave controllers. When a slave controller has a program, this program would always operate in Local mode.

The following table describes the modes of motion and whether this mode will work in Global or Local Mode:

Mode of Motion	Basic description	Commands	Global	LOCAL
Relative Independent	Each axis operates independently and motion is	PR, AC, DC, SP	YES	YES
Axis Positioning	specified with a relative distance, velocity,
	acceleration and deceleration. The axis follows the
	prescribed velocity profile.
Absolute Independent	Each axis operates independently and motion is	PA, AC, DC, SP	YES	YES
Axis Positioning	specified with an absolute position, velocity,
	acceleration and deceleration. The axis follows the
	prescribed velocity profile.
Independent Jogging	Each axis operates independently and the axis	JG	YES	YES
	follows a prescribed velocity profile with no final	AC, DC
	endpoint. The motion is specified with velocity,	ST
	acceleration and deceleration. Motion stops on Stop
	command.
Linear Interpolation	2 thru 8 axes of coordinated motion. The path is	LM	NO	YES
	described by linear incremental segments and vector	LI, LE
	velocity, vector acceleration and vector	VS, VA, VD
	deceleration. The vector motion follows the
	prescribed velocity profile.
