The LE-30CTA operates as a closed-loop tension controller. It receives real-time feedback from tension detectors (load cells), compares it to the target setpoint, and calculates the necessary correction output via an advanced PI (Proportional-Integral) control loop. Key Specifications 100V to 240V AC (+10% / -15%), 50/60 Hz. Power Consumption: Approximately 30 VA. mitsubishi tension controller le 30 cta Manual

Compatible with Mitsubishi LX-TD series strain-gauge tension detectors (usually 2 channels for left/right balance). Control Output Channels:

Increase the Integral Time (I) or lower the Proportional Gain (P) . Inspect mechanical couplings, drive belts, and magnetic powder brakes for physical wear. 6. Maintenance and Safety Best Practices

Before diving into the manual’s procedures, you must understand the hardware. The Mitsubishi Tension Controller LE-30CTA Manual typically refers to these core components:

Safety is the foremost priority. The following "DANGER" warnings must be strictly followed during installation and wiring: The Mitsubishi LE-30CTA is a closed-loop tension controller,

Use shielded, twisted-pair cables for all detector inputs to prevent interference from high-voltage motor lines. Control Output Connections

With no material on the rollers, use the "Zero" function in the calibration menu.

Navigate to the parameter menu using the key and select the Zero Calibration parameter ( ZERO ).
