Digitaler Spannungs-Controller KDT series

Bahnfür Kupplung und Bremse

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. The KDT-C-1000 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 its outputs according to the measured tension and a preset tension value. Operators can tune proportional gain and integral time through the controller menu to match different materials, machine structures, roll diameters and operating speeds. Forward/reverse adjustment direction selection increases installation flexibility.

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. Additional outputs: 1 × 0–5V analog auxiliary output (configurable to 0–10V) for integration with external equipment.

Dual-Station Roll Change Control
Dedicated dual-station roll change functionality includes dual-station switching, shaft-change output ratio setting and preset output restoration during roll change to reduce tension fluctuation and support continuous production with frequent roll replacement.

Hall Switch Automatic Pause Function
The controller supports an automatic pause when no Hall pulses are detected (e.g., machine stopped), preventing continuous output increase while stationary and reducing excessive tension at restart.

Taper Tension Control
Taper control is supported to modify tension characteristics as roll diameter changes during winding. This allows improved roll quality for materials sensitive to constant winding force.

RS485 Communication & Multi-Controller Synchronization
RS485 integration enables communication with industrial control systems. The controller supports configurable communication address and baud rate and synchronized operation of multiple controllers for coordinated multi-point tension control.

Easy On-Site Operation
Menu-based parameter adjustment and an LCD with 40-segment digital indication provide straightforward on-site commissioning and monitoring of measured tension and preset values. Important operating parameters can be tuned directly on the controller without complex programming interfaces.
