AC200 frequency inverter can provide 150% of rated torque (V / F, no PG high performance vector control) at 0.5Hz, and provide 200% of rated torque (with PG high performance vector control) at 0Hz.
.In addition to the motor rotation, static self-identification functions of previous models, the rotation self-learning function of hoisting motors can automatically identify the direction of the encoder signal to simplify the debugging process.
.Newly Developed a Completely-Static Self-Identification Method:
Even if the motor cannot disengage the load, it can accurately identify all the parameters of the motor, which improves the adaptability of vector control. The high performance vector control can adapt to different applications.
.Support a variety of encoders: Differential encoder, open collector encoder, U / V / W encoder, rotary transformer encoder, which facilitate the realization of closed-loop high-performance vector control.
The maximum frequency is up to 600Hz under vector control mode that it is capable of achieving 12 times of precise speed output within field-weakening speed regulation range.
