Simple PLC, multistage speed operation	It implements up to 16 speeds via the simple PLC function or combination of DI terminal states.
Built-in PID	It can keep constant output voltage automatically when the mains voltage changes.
Automatic voltage regulation(AVR)	Automatically maintain a constant output voltage when grid voltage changes.
Over voltage/Over current loss of speed control	Automatic limit of the current and voltage during the operation, prevent frequent over current and over voltage
Rapid current limit	Minimizing over-current fault and protect the normal operation of converter.
Torque limit and control	"Excavator" characteristics, automatic limit of the torque during the operation, to prevent frequent over-current trip. Closed-loop vector mode torque control can be achieved.
