Overview
The XW Machinery KDT-C-1000 Automatic Web Tension Controller is a cost-effective C-type model in the KDT Automatic Series designed for automatic tension control in winding, unwinding, slitting, printing, laminating, coating and other roll-to-roll processing machinery. It focuses on practical on-site adjustment, dual-station roll-change control, automatic tension feedback and straightforward operation suitable for OEM machine builders and production lines.

Key Features

• Fully automatic constant tension control
• Designed for tension-feedback winding and unwinding applications
• KDT Series C-type model with 1000 N·m range designation
• Adjustable proportional gain and integral time (PI tuning)
• Forward and reverse adjustment mode selection
• Two tension detector inputs
• Dual 24V constant-current outputs (direct drive for magnetic powder clutches/brakes)
• Single 0–5V analog auxiliary output; configurable to 0–10V
• Dual-station roll change control and adjustable shaft-change output ratio
• Taper tension control for roll-diameter compensation
• Hall switch automatic pause function to stop adjustment when machine stops
• Limit output relay
• RS485 communication with configurable address and baud rate
• Support for multi-controller synchronized operation
• LCD display with 40-segment digital tension indication and menu-based parameter adjustment

Adjustable Automatic Tension Control
The KDT-C-1000 continuously receives feedback from two tension detectors and automatically adjusts outputs according to the measured tension and preset tension value. Proportional gain and integral time can be tuned via the menu to match different materials, machine structures, roll diameters and line speeds. Forward/reverse adjustment selection increases installation flexibility.

Dual 24V Constant-Current Output
The controller provides two 24V constant-current output channels to drive magnetic powder clutches and magnetic powder brakes directly. An auxiliary analog output (1 × 0–5V, configurable to 0–10V) is provided for integration with external control equipment.

Dual-Station Roll Change Control
Dedicated dual-station roll change functionality supports dual-station switching, shaft-change output ratio setting and preset output restoration during roll change to reduce tension fluctuation and maintain stable production during roll replacement.

Hall Switch Automatic Pause Function
When no Hall pulse is detected (machine stopped), the controller can pause automatic tension adjustment to prevent excessive output during stoppage and reduce restart tension spikes.

Taper Tension Control
Taper control allows modification of tension characteristics as roll diameter changes during winding, improving roll quality for materials sensitive to winding force distribution.

RS485 Communication & Multi-Controller Synchronization
RS485 interface with configurable address and baud rate enables integration into industrial control systems. Multiple KDT controllers can operate synchronously for multi-point tension control in complex machines.

Easy On-Site Operation
Menu-based parameter adjustments and an LCD with 40-segment digital tension indication simplify commissioning and on-site tuning for operators without complex programming.
