The Working Principle and Performance of KDR Series Frequency Converters

KDR series frequency converter adopts six-level modulation technology, high-performance vector control algorithm, and built-in advanced auto self-tuning technology.

The six level modulation technology adopted by KDR series frequency converter, by adjusting the output voltage waveform and improving the output power factor, can reduce the harmonics of the motor and improve the control accuracy of the motor.

High performance vector control algorithm, carrying comprehensive vector control algorithm, is used for controlling the motor. It can reduce the noise, vibration and torque ripple of the motor. It can also accurately control the output speed, torque and other parameters of the motor, and has strong overload capability and excellent dynamic performance, which can meet the requirements of various automation systems.

The built-in advanced auto-tuning technology can automatically optimize the parameters of the motor according to the characteristics of the motor itself, thus avoiding manual matching.

KDR series frequency converter also has strong network communications and has more than 20 kinds of basic network communication options, which supports TCP/IP Ethernet, EtherCAT, RS485, CAN bus, USB, PROFINET, PROFIBUS, DEVICENET, MODBUS, etc. It can meet the needs of various networks and fieldbus protocols.

Conclusion

KDR series frequency converter has wide application fields, and its performance is also very excellent. With the development of industrial technology, it will be more widely used. Its accurate speed control, energy saving and strong overload ability can meet the needs of various automation systems.
