SIMATIC S7-1500T RotaryKnife

  • Associated product(s)
The SIMATIC application RotaryKnife is part of the Converting Toolbox and was developed with the objective to provide a flexible solution for cutting or perforating web material. The rotary knife is needed in many converting machines to cut or perforate a continuous material.

The materials can differ a lot. Everything, between one-layer paper up to stainless steel is possible. Thus, the possible rotary knife machines differ a lot (paper cross cutter, eccentric shear, pendulum shear).
Therefore, different suitable motion profiles were developed (constant acceleration, jerk limiting, polynomial, sinusoidal or combination) or freely definable cutting profiles.

The standard application is based on the system platform SIMATIC S7-1500T and provides different Rotary Knife functionalities. The application includes a machine mode manager, the cam calculation, print mark synchronization, an example HMI and much more. This application consists of both. Libraries which can be integrated in the user TIA Portal project and also a complete demonstration project.

The AddOn DC Link Pre Control (=DCLPC) is used to pre-control the DC link voltage according to the load and thus to reduce the gridpeaks.
