Add energy-saving monitoring function to visually display energy consumption data; The V/F curve can be adjusted at 5 points to adapt to different load characteristics.

Support regenerative braking avoidance function to optimize energy utilization.

Function Expansion and Compatibility

Equipped with RS-485 communication interface and supporting Modbus RTU protocol, it facilitates remote monitoring and multi device collaboration.

Compatible with PTC thermistor input, supports simple flux vector control, and can output 120% torque at 3Hz.

Provide scenario based functions such as multi pump control and intermittent/timed restart to enhance system flexibility.

Long lifespan and easy maintenance

Using long-life components, the design has a lifespan of up to 10 years and built-in lifespan diagnosis and warning functions. Supports both forced air cooling and self cooling modes, suitable for harsh industrial environments.
