22.2 Characteristics of "Tangential control" function
Problem definition
Follow-up control for the rotary axis must be implemented so that the axis is always
positioned at a specified angle to the tangent on a programmed path of two leading axes.

Figure 22-1 Example of a tangential control with an angle of zero degrees to the path tangent
In the figure, X and Y are the leading axes inside which the path is programmed. C is the
following axis, the position of which is determined by the control depending on the leading
axis path and the desired angle between the tangent and alignment in C.
The tangential control will function only if the leading axes are used as path axes. A leading
axis which is programmed as a positioning axis (POS or POSA) does not specify values
required for the follow-up control function.
