: The LE-30CTA includes specialized functions like weak excitation (improves torque at low speeds) and automatic polarity judgment , which ignores wiring specifications (compression vs. tension) to simplify setup.

After March 31, 2031, Mitsubishi Electric will no longer accept repair requests. Even within the repair support period, repairs may be impossible if parts are unavailable. Users are strongly encouraged to plan for replacement with the LE7‑40GU‑L or an alternative tension control solution.

Ensure you are using an adequate test weight during span adjustment. Check if the load cell layout mechanically binds or hits a physical stop. Tension Drifts or Hunts Continually mitsubishi tension controller le 30 cta Manual

Connect the ground terminal to a dedicated, high-quality ground (Class D grounding, resistance ≤is less than or equal to Ωcap omega ). Do not share this ground with high-current motor lines. Tension Detector (Load Cell) Input : Equipped with 2-channel DC 5/12/24V inputs and

: Sometimes, online forums or communities focused on industrial automation and control systems can be very helpful. Members might have access to or share documentation, including manuals.

The unit is designed to support multiple control modes, most notably (using feedback from load cells) and Manual Control (allowing operators to set a fixed output current), ensuring flexibility during maintenance or startup phases.

Connect directly to the OUT+ and OUT- DC 24V power amplifier terminals. Ensure the load current does not exceed 2.7A. For Inverters/Servos: Use the ANALOG OUT terminals (

Mitsubishi LE-30CTA Tension Controller is a high-precision device designed to automate the tension of web materials—such as paper, film, and foil—by adjusting the torque of a clutch or brake based on feedback from tension detectors. Key Features & Technical Overview After March 31, 2031, Mitsubishi Electric will no

The "Manual" aspect of the LE-30CTA is most critical during the commissioning phase. The front panel typically features a digital display and keypad for parameter configuration.

PI tuning parameters are set too aggressively, or mechanical components exhibit excessive backlash.

or less). Never share a ground wire with heavy machinery or inverter drives. Tension Detector (Load Cell) Inputs

Ensure the web path is completely empty. No material should touch the tension rollers.

The LE-30CTA was designed for markets requiring a Chinese display interface, while the LE-30CTN (with Japanese display) serves as its Japanese counterpart. Both belong to Mitsubishi’s full‑automatic tension control unit series, which also includes the LE-40MTA/LE-40MTB and the LE-40MD diameter calculation unit.
