Sensorless vector control ac drive frequency inverter 220v/380v

1.Advanced vector control algorithm，can realize the decoupling control of motors, and reach SVC current vector control mode and V/F control mode

2.150% low frequency moment output,1:100 speed control range, control accuracy of the non PG vector control speed can reach to 0.1%

3.Frequency inverters between 0.75kw~18.5kw with built-in brake unit,if fast-action braking is needed,can connect brake resistance directly; 160kw and up with direct current(DC) reactor ,which can increase the power factor of the output side, increase efficiency and stability of the AC Driver, eliminate the influence of higher harmonics produced at the input side toward the frequency inverter,decrease the interference to periphery

4.Built-in auto-compensation torque function,built-in PID regulator and built-in RS485 communication interface, provide full support to MODBUS communication protocol

5.Restart function of torque tracking ,realize smooth and non-impact start of the revolving motor
