SIMATIC S7-1500T Flying Saw
https://support.industry.siemens.com/cs/document/109744840/
The application example provides a flying saw on the controller platform SIMATIC S7-1500T. A continuous moving material (e.g. foil, metal, paper, corrugated, steal profiles, etc.) can be cut on the fly. Functions: Automatic mode, immediate cut, cut to length or cutting mark, virtual or real master.

Flying material processing is necessary if the process takes a certain time. Since the material movement shall not influence the material processing, the processing device need to move synchronous to the web.
Therefore the saw axis (following axis) synchronizes position based to the material (leading value).
Once moving synchronous, the material processing is started (e.g. sawing, cutting, embossing, die-cutting).
After the material processing is finished the processing device stops and usually returns to the start position.

The application example "Flying Saw" for fast and easy implementation of this kind of technology is available in two options:
Function block including example project "FlyingSawBasic"
Standard application from the Converting Toolbox "FlyingSawAdvanced"

Function block including example project "FlyingSawBasic"
The application example "FlyingSawBasic" provides a clear structured and ready-to-power-on solution to realize a flying saw with SIMATIC S7-1500T.
The appropriate example project "FlyingSawBasic" is mainly programmed in the programming language KOP/FUP and covers different areas of use.
The programs can be used directly or adapted to own needs. The included HMI project can be used directly for test and simulation purposes or can be adapted to the user specific case of application.

Standard application from the Converting Toolbox "FlyingSawAdvanced"
The components of the SIMATIC Converting Toolbox have a common philosophy. Beside the technological functions (e.g. winding, tension control, flying saw), the applications use a standardized interface to control all necessary axis functions. Therefore a uniform user interface is provided. Via this interface the user can operate all important axis functions (e.g. referencing, inching, positioning, etc.) as well as additional functions like setup mode.
The basis for this is the standard application "SIMAITC Axis Control" (48816191)
https://support.industry.siemens.com/cs/document/48816191/
In this way it is possible to realize a uniform and standardized axis control, independent from the used technology function.

The components of the Converting Toolbox are well matched and can thus be integrated together into a machine concept (application)
The flying saw operation sequences can be realized in the corresponding operating modes or through the operating mode transitions. The user thus influences the flying saw only by specifying the desired operating mode.

Control via mode manager
Idle position: Axes enable and travel to defined start or service position
Automatic: Process mode
Manual: Uniform interface to control the basic axis functions like referencing, inching, ...
The axes are operated with an integrated function block for axis control.
