Terminal-Peripheral equipment control

Control start/stop with the contact or button to simply realize the automation control of the entire equipment system.

Vector?control?0?

Real time estimates speed information of the motor only, without feedback control, real-time closed-loop control of the current all the way, 0.50 Hz outputs rated torque of up to 150%, track load change and limit output current automatically to make it not exceed the permitted maximum current value.No overcurrent error even if load mutation, rapid acceleration and deceleration to realize high performance and high reliability configuration of the universal Inverter.

Vector?control?1?

Not only real time estimates speed information of the motor, but also conduct feedback control, real-time closed-loop control of both the speed and current all the way, which can realize not only speed control but also torque control, and can translate universal AC induction motor into AC speed regulation motor and AC torque motor by adopting such kind of drive mode. This is a real vector control Inverter without external speed sensor.
