KDT-C-1000 Automatic Web Tension Controller | XW Machinery China Factory Manufacturer & OEM Supplier

Cost-Effective Dual-Station Automatic Tension Controller for Winding & Unwinding

The XW Machinery KDT-C-1000 Automatic Web Tension Controller is the C-type model of the KDT Automatic Tension Controller Series, designed for practical and cost-effective automatic tension control in winding, unwinding, slitting, printing, laminating, coating, and other roll-to-roll processing machinery.

The KDT-C-1000 is positioned as a cost-effective dual-station automatic tension controller, combining automatic tension feedback, adjustable proportional and integral control parameters, dual 24V constant-current outputs, taper tension control, dual-station roll change functions, and RS485 communication.

As a professional China Automatic Web Tension Controller manufacturer, XW Machinery provides factory-direct supply, OEM customization, and wholesale solutions for machinery manufacturers, automation integrators, importers, distributors, and industrial buyers worldwide.

Unlike more function-intensive tension controllers designed around advanced machine integration, the KDT-C-1000 focuses on practical operation, flexible on-site adjustment, reliable dual-station roll change control, and competitive factory pricing.

It is especially suitable for OEM machine builders and production lines requiring stable automatic tension regulation without unnecessary control complexity.

Adjustable Automatic Tension Control

The KDT-C-1000 Automatic Tension Controller continuously receives feedback from two tension detectors and automatically adjusts its output according to the measured tension and preset tension value.

Instead of relying on a fixed control response, the KDT-C-1000 allows operators to adjust the proportional gain and integral time through the controller menu.

This makes it possible to tune the controller according to different materials, machine structures, roll diameters, operating speeds, and required tension response.

The controller also supports forward and reverse adjustment direction selection, making installation and commissioning more flexible for different winding and unwinding machine configurations.

This parameter-adjustable control concept makes the KDT-C-1000 particularly suitable for applications where operators or machine builders need convenient on-site tension tuning.

Dual 24V Constant-Current Output

The KDT-C-1000 provides two 24V constant-current output channels designed to drive magnetic powder clutches and magnetic powder brakes directly.

This dual-output configuration makes the controller suitable for winding and unwinding systems using two tension control actuators or dual-station machine configurations.

The controller also provides:

• 1 × 0–5V analog auxiliary output
• Configurable 0–10V analog output

The auxiliary analog signal can be used for compatible external control equipment according to the machine control design.

This combination provides a practical interface for integrating the KDT-C-1000 into industrial winding and converting machinery.

Dual-Station Roll Change Control

One of the main advantages of the KDT-C-1000 is its dedicated dual-station roll change control functionality.

The controller supports a dual-station switching system together with an adjustable shaft-change output ratio.

During roll changeover, the preset output ratio can be restored to help reduce sudden changes in tension when switching between winding or unwinding stations.

This function is especially useful for machines requiring frequent roll replacement or continuous production.

Typical dual-station functions include:

• Dual-station switching
• Shaft-change output ratio setting
• Preset output restoration during roll change
• Automatic tension adjustment after station switching
• Reduced tension fluctuation during roll changeover

For OEM machinery manufacturers, these dedicated functions provide a straightforward way to integrate automatic tension control into dual-station winding and unwinding equipment.

Hall Switch Automatic Pause Function

The KDT-C-1000 includes a practical Hall switch pause function designed for machines where automatic adjustment should stop when the machine is stationary.

When no Hall pulse is detected for approximately one second after the machine stops, the controller can automatically pause tension adjustment.

This helps prevent the controller from continuously increasing output while the machine is stopped, reducing the possibility of excessive tension when the machine restarts.

The function is especially useful in winding, unwinding, printing, slitting, and converting equipment that frequently starts and stops during normal production.

Taper Tension Control

The KDT-C-1000 supports taper tension control for winding applications.

As the roll diameter changes during winding, taper control can be used to modify the tension characteristics according to the machine and material requirements.

This function is useful when processing materials where maintaining exactly the same winding force throughout the entire roll can affect roll quality.

By adjusting the tension characteristics during roll buildup, the KDT-C-1000 provides machine builders with additional flexibility for different winding processes.

RS485 Communication and Multi-Controller Synchronization

The KDT-C-1000 supports RS485 communication for integration with industrial control systems.

Communication parameters including the controller address and baud rate can be configured according to the machine control requirements.

The KDT Series also supports multiple-controller synchronized operation, making the system suitable for machinery using several coordinated tension control points.

This provides greater flexibility for OEM equipment manufacturers designing multi-station winding, unwinding, printing, laminating, and converting systems.

Easy On-Site Operation

The KDT-C-1000 is designed around straightforward menu-based operation.

Operators can use the menu selection and adjustment controls to configure important tension control parameters directly on the controller.

The display combines an LCD interface with a 40-segment digital indication system for monitoring measured tension and preset tension values.

Important operating parameters can be adjusted directly during machine commissioning, making the KDT-C-1000 suitable for production environments where operators need convenient access to tension settings without a complicated programming interface.
