Figure C-14. Coordinate System 2 Orientation (Clockwise or G2 Motion)
C.4.19.1. Clockwise Circular Axes Plane
By default, this command will produce circular motion in the X and Y axis plane as
shown in Figure C-15. However, this command can produce motion in any one of three
planes, where, each plane is defined by two of the three axes of the coordinate system.
The three axes of coordinate system #1 and #2 are defined by the G16 and G26
commands, respectively. The 2 axes plane that is used within coordinate system 1 and 2,
is selected by the G17/G18/G19 and G27/G28/G29 commands, respectively.

C.4.20. Coord2I
This task parameter specifies which task axis is the Coord2I axis for coordinate system 2.
This axis must be a linear type. The task X axis does not have to be the Coord2I axis.
Coordinate system axes Coord2I, Coord2J, and Coord2K are used only as axes identifiers
of a three dimensional system. Any task axis can be assigned to any of the three
coordinate system axes. This mapping in conjunction with the selected plane (see
Coord2Plane parameter) determine which task axes can be used for circular motion. This
parameter is 0 based, where 0 represents the first axis, typically named X.
The G26 command may be used to assign this parameter more easily within a CNC
program however, it will not be saved to the task parameter .Ini file, requiring it to be
set within all CNC programs.
