30 Cta Manual - Mitsubishi Tension Controller Le

Mitsubishi Electric's LE-30CTA is an advanced, user-friendly tension controller that has been discontinued as of 2024. Maintaining a legacy system requires a solid understanding of its functionalities, careful technical management, and a strategy for eventual replacement.

: Always turn off all power phases externally before setting DIP switches, cleaning, or retightening terminals. Maintenance and Troubleshooting LE-30CTN APPLICATION MANUAL - Contentstack

| Parameter | Value | |-------------------|--------------------------------| | Power Supply | 100–120 VAC or 200–240 VAC (depending on variant) | | Control output | 0–10 VDC / 4–20 mA (configurable) | | Tension input | Load cell (mV/V) or DC voltage | | Display | 7-segment LED, 4 digits | | Setup parameters | Gain, zero, taper, response time |

The is an automatic tension controller designed for high-performance unwinding, intermediate, and rewinding processes. 1. Core Functions & Compatibility

Includes a "weak excitation" function to improve torque response during low-speed starts. NanaSupplier.com Essential Safety Cautions Grounding: Class D grounding

Measure the coil resistance of the brake or clutch unit. Replace the component if an internal short circuit is present. E.05 – Memory Write Error

The LE-30CTA features self-diagnostics that trigger alarm codes when anomalies occur. Er1: Tension Detector Open Circuit Are you controlling an

Hang a known test weight (ideally 50% to 100% of your maximum target operating tension) onto the rope. Navigate to parameter C02 (Span Target Value).

PI tuning parameters are set too aggressively, or mechanical components exhibit excessive backlash.

The system operates based on internal parameters divided into basic user settings and advanced engineering parameters. Below are the core parameters required for stable operation. Parameter Code Description Default Value Adjustable Range Target Tension 0.0 to Max Scale Sets the desired tension setpoint during AUTO mode. P02 Proportional Gain (P) 0.1% to 100.0% Adjusts the speed of response to error deviations. P03 Integral Time (I) 0.1s to 999.9s Eliminates steady-state tension errors over time. P04 Derivative Time (D) 0.0s to 99.9s Dampens rapid oscillations and sudden shocks. P10 Taper Coefficient 0.0% to 80.0% Decreases winding tension as roll diameter grows. P15 Output Limit 0.0% to 100.0% Caps the maximum voltage/current sent to the brake. 6. Troubleshooting Error Codes

: Switches from manual to automatic feedback control using the "AUTO" key (#15). In this state, the controller matches material tension to a preset value using real-time feedback.

Controls response speed. Higher values increase speed but risk oscillation. Integral Time (I) 5.0 seconds

Zero and span calibration must be performed before the system can operate accurately. Ensure the web material is completely removed from the tension sensing roller before starting. Step 1: Sensor Zero Adjustment Navigate to the calibration menu on the display interface.
