| Param | Name | Exclusive Setting Advice | | :--- | :--- | :--- | | | Target Tension Unit | 0=kg, 1=N, 2=lb. Change only with no roll loaded. | | F01 | Max Tension Range | Set to 120% of your max operating tension. Exclusive: Prevents ADC saturation. | | F02 | Load Cell Sensitivity (mV/V) | Enter value exactly from load cell certificate. Even 0.1 error causes 5% reading drift. | | F05 | Proportional Gain (P) | Start at 2.0. Low inertia webs (film) need <1.5. Heavy paper >3.0. | | F06 | Integral Time (I) | Start at 2.0 seconds. Too low = hunting. Too high = sag response. | | F10 | Dancer Pot Range (0-10V) | Exclusive: Set to 10.00 only if using full 330-degree pot. For 270-degree, calculate (270/330)*10. | | F23 | Soft Start Time | Ramp setpoint over 3–10 sec. Exclusive: For elastic webs (stretch film), use 8 seconds minimum. | | F31 | Zero Calibration Offset | Run with no web. Press SET for 2 sec. Do NOT do this with load cell pre-tension. | | F40 | RS-485 Station Address | Default = 01. Exclusive: For multi-zone systems, each LE-30CTA must have unique address. | Mitsubishi LE-30CTA The Mitsubishi Tension Controller LE 30
