ECF300 series high performance frequency converter

Advanced motor drive technology, whether it is to drive asynchronous motor or synchronous motor, or linear motor can achieve high performance of the current vector. Asynchronous motor, synchronous motor and linear motor transducer can be used in general. When the fundamental frequency is 50Hz, the 150Hz operation can reach 15% rated torque.

High precision torque and speed control.
, unique "excavator" adaptive control characteristics, during the operation of motor torque limit automatically limit, effectively inhibit over-current trip frequently.
Wide voltage input, output voltage automatic voltage regulator (AVR), the instant power off, the ability to adapt.
New parameter copy function to facilitate the customer to copy the parameters.
Bidirectional PID control, fast response.
High education rate operation.
LCD Chinese character display keyboard.
Password protection function to prevent malicious changes to parameters.
Rich I/O interface to meet the special requirements of the industry.
