Press . The controller calculates the scaling factor based on the voltage shift caused by the physical weight. 4. Parameter Settings and PI Tuning
Ensure the web material is completely removed from the tension sensing rollers. The rollers must be entirely free of external weight.
However, they require new sensor wiring understanding. If your LE-30CTA manual feels like Latin, the digital transition will be French. Keep the old manual for sensor wiring reference.
: Generally found between $715.00 and $2,116.00 depending on condition and supplier. mitsubishi tension controller le 30 cta Manual
Connect the main AC power supply here. Use a dedicated circuit breaker.
Some third-party companies (e.g., Radwell, PLC Center) offer flat-rate repair for the LE-30CTA. Typical failure: capacitor aging in the power supply. Cost: $400-$700.
Understanding the hardware layout is the first step to utilizing the LE-30CTA. Based on the and supplier data sheets, the specifications are broken into Electrical and Environmental categories. Parameter Settings and PI Tuning Ensure the web
The LE-30CTA operates by receiving signals from tension detectors (load cells). It compares this actual tension against a user-defined setpoint. To maintain balance, it outputs a control signal (typically 0–24V DC or 0–10V) to regulate the torque of the driving or braking element.
A frequent error in the is the recommendation to short the unused sensor wires if only one tension detector is connected. Specifically, if only one side is used, the Green and White wires of the unused side must be shorted together.
Connect to a dedicated ground (Class D grounding, resistance If your LE-30CTA manual feels like Latin, the
When the controller encounters an issue, it displays specific faults or exhibits distinct operational anomalies. Symptom / Error Code Probable Cause Corrective Action Short circuit in output line or faulty powder brake. Check clutch/brake coil resistance. Inspect output wiring. Err 02 (Sensor Fault) Broken sensor wire or defective load cell.
: 0 to 24V DC for clutches/brakes or 0 to 5V DC torque commands for servo amplifiers. I/O Allocation : 32 mixed input/output points.
Correct wiring is essential to prevent electrical noise interference and protect internal circuitry. Always isolate the main power source before making any connections. Power and Grounding Connect the AC power line to terminals and N .
Mitsubishi has discontinued the LE-30CTA, supporting it with the LE-40MTA and later the LE-50 series. However, the LE-30CTA manual is still available as a historical document on Mitsubishi’s global support portal (FA Global) or through third-party industrial manual archives.
