Integrated winder function

Integrated winder functions

The DCS550 is equipped with a winder function with pre-

defined macros for the four most commonly used winder

types:

Velocity control

Calculates the diameter and rotation speed set value.

The diameter is used to adjust the speed controller to all

winding sizes. There is no tension control. All other macros are

included in this basic structure.

Indirect tension control

Controls the tension with the help of preset charts for friction

and moment of inertia (open loop).

This structure provides a very robust control behaviour

because no physical tension measurement is required.

Direct tension control

Closed loop for physical value of tension

The tension is measured with a load cell and transferred to the

drive as an analog actual value. The DCS550 is equipped with

a free PID-controller that can be integrated into the control

loop with the “Tension Control” macro.

Dancer control

Controls the tension with the weight of the dancer roll

(closed loop).

The dancer has to be kept in the right position with additional

speed set values. The PID-controller of the DCS550 can also

control the positioning of the dancer roll. The position of the

dancer roll is transmitted to the controller as an analog actual

value.

Commissioning assistant

For an easy winder set-up, all different winder types can be

configured and commissioned using a graphical assistant.

The assistant is part of DriveWindows Light PC-tool.

The rating for friction and inertia can be determined by auto

tuning.

Example: direct tension control (closed loop)
