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

Fonctionnement principal
The KDT-C-1000 continuously receives feedback from two tension detectors and automatically adjusts outputs according to the measured tension and a preset tension value. Operators can tune proportional gain and integral time through the controller menu and select forward/reverse adjustment modes to match different machine configurations and materials.

Product Features

• Menu-based parameter adjustment for easy on-site commissioning

Dual 24V Constant-Current Output & Auxiliary Signals
The controller provides two independent 24V constant-current channels suitable for driving magnetic powder clutches or magnetic powder brakes directly. An auxiliary analog output (1 × 0–5V) is provided and can be configured up to 0–10V for integration with external control equipment.

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

Hall Switch Pause Function
When no Hall pulse is detected after the machine stops, the controller can automatically pause tension adjustment (e.g. after ~1 second). This prevents continuous output increase while the machine is stationary and reduces risk of excessive tension at restart.

Taper Tension Control
Taper control is supported to change tension characteristics as roll diameter changes during winding. This allows tuning of winding force across roll buildup for materials requiring tension variation to maintain roll quality.

RS485 Communication & Synchronization
RS485 interface is supported with configurable address and baud rate for integration with machine control systems. Multiple KDT units can operate synchronized for machines requiring coordinated tension control at several points.
