Mitsubishi Tension Controller LE-30CTA is a precision automatic control device designed to manage the tension of long materials—such as paper, film, foil, and wire—during industrial winding, unwinding, and intermediate processes. By regulating the electrical signals sent to actuators like magnetic powder clutches or brakes, this controller ensures material integrity and prevents defects like wrinkling or breakage. dl.mitsubishielectric.co.jp Core Functions and Operational Principles
: Includes linear, ring, sampling, and periodic pulse counter functions to assist in reel diameter calculation and consistent output. Voltage Generation
Zero Adjustment: With no material on the rollers, use the "Zero" potentiometer or menu setting. This tells the controller that the current weight of the roller equals "0" tension. mitsubishi tension controller le 30 cta manual exclusive
Span Adjustment: Hang a known weight (e.g., 10kg) over the tension roller in the exact path the web would take. Adjust the "Span" setting until the display matches the weight of the test load. 4. Exclusive Operating Tips for the LE-30CTA
The Mitsubishi Tension Controller LE-30 CTA is a sophisticated device designed to manage and regulate tension in various industrial applications, including printing, unwinding, and winding processes. This manual provides an in-depth look at the features, operation, and maintenance of the LE-30 CTA, ensuring optimal performance and longevity of the controller. Voltage Generation Zero Adjustment: With no material on
Note: The exact parameter names and ranges vary by firmware version and hardware revision; use these as conservative starting points and follow the controller's parameter list for precise entries.
Diameter presetting
You can manually input starting core diameter and final roll diameter for closed-loop control without a dancer roller. Adjust the "Span" setting until the display matches
The Mitsubishi Tension Controller LE-30CTA is an automatic control device designed for high-precision management of long materials such as paper, film, wire, and sheets during unwinding, intermediate, and rewinding processes. It typically operates in conjunction with LX-TD or LX-TD-928 type tension detectors to maintain stable tension in roll-to-roll applications. 1. Key Technical Specifications
