Overview
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. It focuses on practical operation, flexible on-site adjustment, reliable dual-station roll change control and competitive factory pricing.

Adjustable Automatic Tension Control
The KDT-C-1000 continuously receives feedback from two tension detectors and automatically adjusts output according to measured tension and the preset tension value. Operators can tune proportional gain and integral time through the controller menu to match different materials, machine structures, roll diameters and speeds. Forward/reverse adjustment direction can be selected to fit various winding/unwinding configurations.

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

Dual-Station Roll Change Control
The KDT-C-1000 offers dedicated dual-station roll change control functionality including dual-station switching, adjustable shaft-change output ratio, preset output restoration during roll change and automatic tension adjustment after station switching. These functions reduce tension fluctuation during roll changeover and support continuous production with frequent roll replacement.

Hall Switch Automatic Pause Function
The controller supports a Hall switch pause function: when no Hall pulse is detected for a short period after the machine stops, the controller can pause tension adjustment to prevent continuous output increase while stationary, minimizing the risk of excessive tension on restart.

Taper Tension Control
Taper tension control is supported to adjust tension characteristics as roll diameter changes during winding. This allows better control of roll build-up and winding quality for materials sensitive to constant force over the roll build.

RS485 Communication and Multi-Controller Synchronization
RS485 communication is supported for integration with industrial control systems. Communication address and baud rate are configurable. The series supports synchronized operation of multiple controllers for coordinated tension control across multi-station machinery.

Easy On-Site Operation
The device is designed for practical on-site commissioning via menu-based operation. The LCD interface with a 40-segment digital indication displays measured tension and preset values, enabling direct adjustments of key parameters without complex programming.
