The following axis position results from the overlay (summation) of the dependent motion
components (FA
the leading axes, and of the independent motion component (FA
The motion components of the following axis are calculated as follows:
Dependent motion component of leading axis 1:
Dependent motion component of leading axis 2:
Independent motion component of the following axis:
Following axis overlay
The overlay of dependent and independent motion components of the following axis is called
following axis overlay.
The independent motion component of the following axis can be programmed with the full
range of available motion commands.
2.5.1.2 Keywords and coupling characteristics
Keywords
Programming is done via language commands, e.g. coupled motion with TRAILON(X,Y,2).
Keywords replace the language commands in generic coupling.
This has the following advantages:
• Coupling characteristics can be programmed individually (see following example).
• Programming of multiple couplings can be done in one block (since keywords do not
