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.
Always start your line in "Manual" to take up the slack, then switch to "Auto" once the web is moving at a steady crawl. 5. Troubleshooting Common Error Codes
Always ensure you download the official Mitsubishi Electric "IB" or "SH" document number for the LE-30CTA to ensure you have the correct wiring schematics for your specific revision. mitsubishi tension controller le 30 cta manual exclusive
The is a "set it and forget it" piece of hardware once calibrated correctly. By following the manual's wiring diagrams and applying the PID tuning tips above, you can significantly reduce material waste and downtime.
Use the analog output (0–10V) to command a motor drive. 3. The Calibration Process (Zero & Span) With no material on the rollers, use the
In the world of web processing—whether you are dealing with paper, film, or textiles—maintaining precise tension is the difference between a high-quality product and a bin full of scrap. The stands as one of the most reliable workhorses in this field.
This means your Gain is too high. Dial back the Proportional (P) setting until the tension stabilizes. By following the manual's wiring diagrams and applying
The unit typically uses the terminals for AC power. Ensure your ground (PE) is connected to a dedicated earth point to minimize electrical noise, which can interfere with sensitive load cell signals. Tension Detector (Load Cell) Input Terminals for the LX-TD sensors are highly sensitive.
