Are you controlling a or an AC motor drive (VFD/Servo) ?

To ensure safe and optimal operation, it is recommended to download the official instruction manual. You can find PDFs from various sources, such as ManualsLib or Scribd.

: You must perform solid grounding (Class D or better, 100 Ωcap omega or less) to ensure the safety of the operator and the unit.

The LE-30CTA features dedicated terminals for strain-gauge inputs. Use shielded twisted-pair cables for these connections: : Signal input from the load cells. The core components of the system controlled by

The following are some common issues that may arise when using the Mitsubishi Tension Controller LE 30 CTA, along with troubleshooting steps:

: Always cut off all phases of the external power supply before wiring or installation to prevent electric shock. Environment

) to send speed or torque correction signals to your external drive. 3. Step-by-Step Calibration and Setup Procedure

Set the target tension required for your material. Are you controlling a or an AC motor drive (VFD/Servo)

Start the machine at low speed. If the tension hunts or oscillates rapidly, decrease the gain.

Before operating the LE-30 CTA, ensure that:

Before running production, you must execute a formal tension calibration sequence to teach the controller how to interpret raw sensor voltages. Step 1: Zero Calibration (No-Load Adjust)

| Terminal | Function | Specification | |---|---|---| | RED/BLK | Tension detector power | DC5V, for LX‑TD type detectors (connect RED=positive, BLK=negative). Can connect one detector left and one right | | +5V/AIC | External potentiometer power | DC5V, 50mA max | | MIC | Contact input common | DC8V, 4.5mA/point, internally supplied | | RUN | Run/stop input | ON = automatic operation, OFF = stop | | MI1/MI2/MI3 | Multi‑function contact inputs | Functions selectable via parameters (output store, output gain 1/2, output ON‑OFF, manual output 1/2, etc.) | | GRL/WHL (left) & GRR/WHR (right) | Tension detector analog input | Connect green/white leads. When using only one detector, GR‑WH on the unused side must be shorted. Auto‑detects compression/tension load | | AI1/AI2 | Analog function input | Functions selectable via parameters (tension setpoint, roll diameter, external tension, taper ratio, manual setpoint 1/2). Accepts DC0–5V voltage signal or 10kΩ potentiometer | | AIC | Analog input common | Analog signal common terminal |
