Your Integral (I) time is likely too long. Shorten the time to make the controller react faster to speed changes. Conclusion
0-24V DC for clutches/brakes or 0-10V for motor drives.
This means your Gain is too high. Dial back the Proportional (P) setting until the tension stabilizes. mitsubishi tension controller le 30 cta manual exclusive
Always use shielded twisted-pair cables for the load cells.
You cannot skip calibration. The LE-30CTA manual emphasizes a two-step process to "teach" the controller what your tension looks like. Your Integral (I) time is likely too long
While the manual tells you what the buttons do, here is how to use them effectively:
Use the power amplifier output if you are controlling a 24V DC clutch directly. This means your Gain is too high
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.
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.
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.
