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

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

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
