China Inverter with Closed Loop Tension Control System Manufacturer, Supplier, Factory
Deyan Electric provides industrial automation solutions for global customers who require stable and accurate control performance. The Inverter with Closed Loop Tension Control System is developed based on the LNC860L series frequency converter platform, helping wire drawing, winding, and unwinding equipment maintain consistent tension during continuous processing. With closed-loop and open-loop tension control functions, this solution is suitable for applications where material quality and production stability are important.
During wire processing, tension fluctuation can directly affect finished product quality. Changes in roll diameter, acceleration, deceleration, or mechanical load may cause problems such as uneven winding, wire deformation, or unstable operation. By integrating tension control algorithms, encoder feedback support, and automatic roll diameter calculation, this inverter helps equipment operators maintain smoother production conditions and reduce adjustment time.
Stable Tension Control
Maintaining constant tension is one of the key requirements in wire and cable manufacturing. Traditional drive systems may require frequent manual adjustments when the coil diameter changes or production speed varies. The LNC860L-based solution provides more accurate control methods to improve winding and unwinding performance.
The Inverter with Closed Loop Tension Control System supports closed-loop tension control and open-loop tension control modes. According to different machine structures and process requirements, users can select the appropriate control method to achieve reliable operation.
Designed for Changing Production Conditions
In continuous wire processing applications, the material load is not always constant. As the roll diameter increases or decreases, the motor load changes accordingly. The built-in mathematical model for tension winding control and automatic roll diameter calculation allows the drive system to respond to these variations more effectively.
-
Constant tension performance: Helps maintain stable tension during winding and unwinding processes, improving product consistency.
-
Automatic roll diameter calculation: Reduces manual parameter adjustment when coil conditions change.
