When the LE-30CTA encounters an operational error, it halts output to protect the equipment. Use this quick reference guide to diagnose system faults. Error Code: "E.01" — Tension Detector Disconnection
Lower the value for quicker correction; raise the value if the system suffers from low-frequency hunting. Derivative Time (D) Default: 0 seconds (OFF)
In the event of a failure, transistor output devices might lock. External circuits should be designed to handle this to avoid accidents.
Increase the by increments of 5 seconds to slow down the correction rate. mitsubishi tension controller le 30 cta manual exclusive
Mitsubishi LE-30CTA is an automatic tension controller designed to regulate the tension of web materials—such as paper, film, foil, and wire—by adjusting the torque of electromagnetic clutches or brakes. It is often used in unwinding, winding, and feed reel applications to ensure stable material processing. Core Functions and Features
: This piece serves as a guide based on available data and is intended for informational purposes. Always refer to the official Mitsubishi documentation and consult with a professional for specific applications and requirements.
: The controller lost signal from the load cell. Check for broken wires, loose terminal screws, or a damaged sensor strain gauge. When the LE-30CTA encounters an operational error, it
The exclusive features of the set it apart from conventional controllers:
It receives real-time signals from tension detectors (such as the LX-TD or LX-TD-909 series) to automatically adjust output based on material behavior. Dual Output Support:
Press the key to finalize calibration. Remove the rope and weights. Advanced Parameter Settings Derivative Time (D) Default: 0 seconds (OFF) In
If tension is unstable, check the grounding and check for interference from high-power cables.
Exclusive error code: If "Er-7" appears during span, the weight is less than 20% of max range. Increase weight or reduce F01.
Understanding the physical and electrical layout of the LE-30CTA ensures proper installation and prevents component damage during commissioning. Technical Specifications 100–240V AC (+10% / -15%), 50/60 Hz. Power Consumption: Approximately 30 VA.
