22.3.2 Definition of axis coupling: TANG
Programming
The programming is carried out using the predefined subroutine TANG( ). The following
parameters are transferred:
Parameter Value
Following axis (rotary axis) Example: C
Leading axis 1 (geometrical axis) Example: X
Leading axis 2 (geometrical axis) Example: Y
Coupling factor Default 1
Identifier of the coordinate system "B"->Basic coordinate system, optional
Optimization "S" = Standard (default) or
"P" = Automatic adaptation of the time
characteristic for following and leading axis
The appropriate axis identifiers are used to specify the axes. The coupling factor is normally
1. The coupling factor of 1 can be omitted, the same applies for "B".
Example of abbreviated call: TANG(C, X, Y)
Examples of possible calls: TANG(C, X, Y,1)
TANG(C, X, Y,1,"B")
Example of complete call: TANG(C, X, Y, 1, "B","S")
22.3.3 Switching on the axis coupling: TANGON
Programming
The axis coupling is switched on using the predefined subroutine TANGON( ). The following
axis to be tracked is specified. This specification refers to the definition of leading and
following axes made beforehand with TANG.
An offset 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 machine data
MD37402 TANG_OFFSET. If the angle is zero both in TANGON and in the MD, the following
axis takes the direction of the tangent.
Example without offset angle: TANGON(C)
Example with offset angle at 90 degrees: TANGON(C, 90).
