ECF200 series high performance frequency converter

1) using the latest generation of TI high speed motor control dedicated DSP, and innovative use of the three nuclear processing technology platform. Ultra high speed operation to ensure the complete implementation of complex vector computing.
2) a new generation of non PG vector control, the use of advanced motor model algorithm, so that open loop torque control to achieve the closed-loop algorithm. The torque response 10ms, steady-state accuracy is less than 5%. Speed ratio of up to 1:200, steady-state speed accuracy of 0.2%. 0.5Hz can output 180% rated torque.
3) PG vector control. Closed loop torque control. On line switching of torque and speed control. Zero servo control of frequency converter. 0Hz can output 180% of the rated torque, stable speed accuracy of up to 0.02%, the dynamic response time is less than 10ms.
4) standard products all the three proofing lacquer processing, and on occasion of the excessive moisture or dust, but also provide protective reinforcing treatment measures, in order to meet the requirements in more harsh environment for long-term stable operation.
5) the full range of over current, over voltage, overload suppression and stall prevention function. Perfect self checking function, wide voltage range design. The first use of a new generation of Infineon IGBT module, higher reliability.
