Assignment between leading axes and following axis

Programming
The programming is carried out using the pre-defined sub-program TANG. The following
parameters are transferred to the control:
● Following axis (additional rotary axis)
● Leading axis 1 (geometrical axis)
● Leading axis 2 (geometrical axis)
● Coupling factor
● Identifier of the coordinate system
Example
TANG(C,X,Y)

Activation of follow-up control

Programming
The programming is performed using the pre-defined TANGON subprogram. When the
tangential control is activated, the name of the following axis which must be made to follow is
transferred to the control. This specification refers to the assignment between master and
following axes made beforehand with TANG (see Section "Assignment between leading axes
and following axis (Page 509)"). An angle between the tangent and the position of the following
axis can be specified optionally when follow-up is activated. This angle is maintained by the
control for as long as the following axis is made to follow. The angle is added to the angle
stored in the following machine data:

11.3 Using tangential follow-up control
The appropriate axis names are used to spec‐
ify the axes.
The coupling factor is generally 1 (default set‐
ting).
The coupling factor can be omitted.
"B" = Basic coordinate system (default set‐
ting)
"W" = Workpiece coordinate system (not
available)
