Improved Control Performance

- Advanced Sensorless Vector Control at Ultra Low Speed

Excellent control performance with all machines thanks to the improvement of torque characteristics at low speeds.

- Sensorless vector control: 200% or greater at 0.5Hz

- Sensored vector control: 150% or greater at 0Hz

- Excellent Response Speeds and Toque Control Performance

Improvement of the torque response characteristic minimizes the speed deviation when the load is changed. (Quick response to a sudden load change is realized.)

- Improvement of Reduced Torque Characteristic

- Expansion of Multi-speed Control Function

- Stable and Strong Torque Operation

- Expansion in The Field Weakening Operation Range

Easy Operation and Maintenance

Various Inverter Display Functions

All the data of the inverter are displayed on the monitor.

- The trip data of each phase are displayed in case of input phase loss and output short

- Temperature on the IGBT

- Others (In-Out voltage, current, frequency, DC voltage, input power, RPM of motor, rotation direction, frequency change, PID Feedback, accumulated operating time (hour, minute), total power up time (hour, minute), error and trip count display)

RUN(0,1,2) Relay Control Terminal Added

Run output terminals (RN0,1,2) are added for user’s convenience

12 User Group Codes

Users can save the preferred codes (Max. 12) for fast and easy operation and set or adjust data in accordance with the characteristics of the loads.
