| 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. | ||
