The LE-40MTA is the direct form-fit successor. It uses the same 50-pin connector and sensor technology. The programming logic is similar, but the manual is newer. You can often swap in 30 minutes.
The LE-30CTA connects to Mitsubishi LX-TD tension detectors using a 4-wire or 2-wire shielded cable network. mitsubishi tension controller le 30 cta Manual
| Terminal | Function | Specification | |---|---|---| | RED/BLK | Tension detector power | DC5V, for LX‑TD type detectors (connect RED=positive, BLK=negative). Can connect one detector left and one right | | +5V/AIC | External potentiometer power | DC5V, 50mA max | | MIC | Contact input common | DC8V, 4.5mA/point, internally supplied | | RUN | Run/stop input | ON = automatic operation, OFF = stop | | MI1/MI2/MI3 | Multi‑function contact inputs | Functions selectable via parameters (output store, output gain 1/2, output ON‑OFF, manual output 1/2, etc.) | | GRL/WHL (left) & GRR/WHR (right) | Tension detector analog input | Connect green/white leads. When using only one detector, GR‑WH on the unused side must be shorted. Auto‑detects compression/tension load | | AI1/AI2 | Analog function input | Functions selectable via parameters (tension setpoint, roll diameter, external tension, taper ratio, manual setpoint 1/2). Accepts DC0–5V voltage signal or 10kΩ potentiometer | | AIC | Analog input common | Analog signal common terminal | The LE-40MTA is the direct form-fit successor
Happy reading and happy controlling!
Check if the "Emergency Stop" or "Inhibit" circuit is closed. You can often swap in 30 minutes
The LE-30CTA has DIP switches inside the chassis. The manual warns: Do not alter these without reading Section 4.2. These switches set:
