Introduction

Converting Toolbox Introduction

The application SINAMICS DCC Winder was developed with the objective to address many of the known winder applications using one application software. If required, the application can be configured and/or also changed. Using the application SINAMICS DCC Winder allows winders and un-winders to be implemented in a wide range of applications, e.g. foil making machines, printing machines, coating machines... The winder application can be used on the following devices: SINAMICS S120, S150, G130, G150 SINAMICS DCM SINAMICS Integrated in SIMOTION D4xx-2

Introduction

Converting Toolbox Scope of Functionality Diameter calculation

Diameter calculation based on ratio between web velocity and winder rotational speed

The diameter is required to e.g. calculate the correct speed of the winder axis from the machine speed

optional there is an integrating calculation methode, a division method, the possibility to interconnect a diameter sensor or a methode with layer counting available


Tools






Introduction

Converting Toolbox Scope of Functionality Taper characteristic

Optional for rewinder, if the tension is reduced with increasing diameter Taper characteristic depends on the actual diameter Decrease can be absolute (N) or relative (% of tension setpoint) four characteristics are implemented: Hyperbolic characteristic with: Max. tension reduction at infinite diameter Max. tension reduction at specified diameter

Linear characteristic with tension reduction when maximum diameter is reached Personal characteristic using 10 points along the characteristic


Tools






Introduction

Converting Toolbox Scope of Functionality Controller adaption

Controller gain of the tension/position controller is adaptable based on the actual diameter

higher gain at higher diameter Controller gain of the speed controller is adaptable based on the

moment of inertia of the roll higher controller performance with high load conditions


Tools






Introduction

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 Inertia compensation is calculated based on the diameter, the

web width, the gear ratio und the material density


Tools






Introduction

Converting Toolbox Scope of Functionality tension operation

Tension operation can only be enabled if the control is in operation and web break detection is not signaling an error

It is recommended to only enable tension operation in machine stand still

Tension or position setpoint will be enabled using adaptable ramp functions

If tension operation is not active, the diameter computer and the speed override are disabled


Tools






Introduction

The maneuvering input can e.g. be connected with an analog input to influence the internal speed setpoint.

Introduction

Converting Toolbox Scope of Functionality Velocity master, synchronize and stop web setpoint

winder can operate as velocity master for the whole machine stop the winder on continuing web, e.g. after flying roll change synchronize a stopped winder to the web, e.g. before splicing

SINAMICS12.06.12 V03.01.00Setpoint Computer Part 2 (Speed setpoint calculation; Master; Stop)

If winder is used as speed master, the internal setpoint for web speed is used for the diameter calculation

tension operation is deactivated when Stop is selected, if a fixed web velocity is set and this value is also used as speed setpoint for the speed master, p22060 has to be set to 1"

When the winder is set as speed master, r21626 shows the reaching of the upper velocity limit, r21627 the reaching of the lower velocity limit.

Introduction

Converting Toolbox Scope of Functionality Execution groups

The required components of the application are enabled via execution groups:


Tools






Introduction

Converting Toolbox Scope of Functionality Execution groups

The execution groups Diameter computer, Setpoint calculator, Control unit are always required, the execution group TensionDancerContr not for indirect closed-loop tension control, the execution groups Winding hardness calculator, Integrating diameter computer and Web break detection - only if the functions are actually required.

For drive systems with the CU320-2 Control Unit, sampling times of 4ms are recommended; for standard settings, this corresponds to the clock cycles of the execution group BEFORE speed setpoint channel for servo - or BEFORE position controller for servo and vector (This execution group is available independent of the activated basic positioner function module).

Sampling times of 8ms or 16ms are recommended for the SINAMICS DCM drive system.
