Preparatory operation for the definition of tangential
tracking:
Activate tangential control for the specified following axis
Deactivate tangential control for the specified following axis
Activate the "Insert intermediate block at contour corners"
function
Delete definition of tangential tracking
Following axis: additional tangential following rotary axis.
Leading axes: path axes, which determine the tangent for
the following axis.
Coupling factor: Relationship between the angular change
of the tangent and the tracked axis
Default: 1
Note:
A coupling factor of 1 does not have to be programmed
explicitly.

Note:
With <

following axis are taken into account in the velocity
limitation of the leading axes. This setting is
especially recommended when using kinematic
transformations.
