Input in absolute and incremental dimensions
The G90/G91 defaults for absolute or incremental dimensions are valid for the intermediate
and circle end points.
With G91, the circle starting point is used as the reference for the intermediate point and end
point.

: Circular interpolation through intermediate point
: End point in Cartesian coordinates. These specifications depend on
the travel commands G90/G91 or ...=AC(...)/...=IC(..)
: Circle center point in Cartesian coordinates (in X, Y, Z direction)
The identifiers have the following meanings:
:
I1
:
J1
:
K1
: Absolute dimensions (non-modal)
: Incremental dimensions (non-modal)
is modal.
Coordinate of the circle center point in the X direction
Coordinates of the circle center point in the Y direction
Coordinates of the circle center point in the Z direction
