"Flying Saw“Prepared Solution

The "Flying saw" Prepared solution provides the software-based solution of a drive task. Flying
saws are used in many production processes. Specifically whenever material is to be machined
during a production process is running. This process does not necessarily has to be a sawing
process. Filling or drilling processes, for instance, are also possible. A primary characteristic of
a flying saw is the length or mark-controlled synchronisation to a production speed.

Tip

TIP!
If you keep the mouse pointer over a symbol on the toolbar for a short time, the
corresponding command is indicated in a "tooltip".

Variable

names

The conventions used by Lenze for the variable names of its system blocks, function blocks and
functions are based on the so-called Hungarian Notation. This notation makes it possible to
identify the most important properties (e.g. the data type) of the corresponding variable by
means of its name, e.g. DIGIN_bIn1_b.

You will find information about the conventions in the appendix of the DDS Online
documentation “Introduction to IEC 61131-3 programming”.
