7.2.3 Technology objects required and synchronous relationships
The following technology objects must be set-up and interconnected with
one another in the following fashion in order to use the core “flying saw”
functions:
Technology objects
The required technology objects are listed according to their function within
the core “flying saw” functions in the following:
• Generating the master (leading) value from the motion of the material
web:
– TO Achse “MaterialAxis” as real positioning or synchronous axis
(maximum configuration)
To determine the position and velocity of the material web as
master (leading) value of the core “flying saw” functions and to
coordinate the motion of the axis – material web from the same
control.
• Coordinating the flying saw axis
– TO axis “FlyingSawAxis” as real synchronous axis
Synchronous relationships
The "flying saw" core functions require the following synchronous
relationships:

The MaterialAxis is the reference quantity for the “flying saw”. For this
purpose, it must be made available to the “flying saw FB” as “positioning
axis”.
