Built-in simple PLC, multiple speeds

It realizes up to 16 speeds via the simple PLC function or combination of DI terminal states 

Built-in PID 

It realizes closed loop control system easily 

Auto voltage regulation

It can keep constant outputvoltage automatically when the mains voltage fluctuation. 

Overvoltage/Over current
stall control

The current and voltage are limited automatically during the running process so as to avoid frequently tripping due to overvoltage/over current. 

Rapid current limit

It can auto limit running current of frequency inverter to avoid frequently tripping

Torque limit and control 

(Excavator characteristics) It can limit the torque automatically and prevent frequently over current tripping during the running process. Torque control can be implemented in the VC mode 

Individualized functions 

High performance 

Control of asynchronous motor and synchronous motor are implemented through the high-performance current vector control technology

Instant power off not stop

The load feedback energy compensates the voltage reduction so that the frequency inverter can continue to run for a short time. 

Rapid current limit

To avoid frequently over current faults of the frequency inverter.
