Converting Toolbox Introduction

The application SINAMICS DCC Line Tension Control was developed with the objective to address many of the known tension control applications using one application software.

If required, the application can be configured and/or also changed.

Using the application “SINAMICS DCC Line Tension Control” allows tension control functionality to be implemented in a wide range of applications, e.g. foil making machines, coating machines, ...

Can be combined with other applications like:

SINAMICS S120, S150, G130, G150

Industry Sector

Converting Toolbox Scope of Functionality – Torque pre-control

Optional compensation of the acceleration/ deceleration torque, resulting

of the moment of inertia to improve the dynamic reaction of the drive

Inertia compensation reduces tension fluctuation based on speed

changes

Inertia compensation is required if indirect tension control is used and

recommended in tension control mode via load cell

Inertia compensation is set up during commissioning based on moment of

inertia

Inertia compensation is calculated based on the web width, the gear ratio

and the material density

Industry Sector

Converting Toolbox Scope of Functionality – tension operation

Tension operation can only be enabled if the fb is in operation

It is recommended to only enable/disable tension operation in machine

stand still

Tension or position setpoint will be enabled using adaptable ramp

functions

If tension operation is not active the speed override is disabled
