Deactivating The Coupling (Tangof); Deleting A Coupling (Tangdel) - Siemens SINUMERIK 840D sl Programming Manual

Deactivating the coupling (TANGOF)

Via the predefined procedure TANGOF(...), a tangential coupling defined with TANG(...)
(Page 940) and activated with TANGON(...) (Page 943) is deactivated. The following axis is
then no longer aligned with the path tangent of the leading axis. However, the coupling of the
following axis to the leading axes is retained even after deactivation, which prevents the
following functions, for example:
● Plane change
● Geometry axis switchover
● Definition of a new tangential coupling for the following axis
Final cancellation of the connection of the coupling of the following axis to the leading axes is
not completed until the coupling has been deleted with TANGDEL(...) (Page 945).

Deleting a coupling (TANGDEL)

A tangential coupling defined with TANG(...) (Page 940) will be retained even after deactivation
of the tangential coupling with TANGOF(...) (Page 945). The existing tangential coupling then
continues to prevent, for example, the following functions:
● Plane change
● Geometry axis switchover
● Definition of a new tangential coupling for the following axis
With the predefined procedure TANGDEL(...), the existing tangential coupling is deleted after
the tangential coupling has been deactivated with TANGOF(...).
