| Built-in PID | It realizes closed loop control system easily. |
| Auto voltage regulation (AVR) | It can keep constant output voltage automatically when the mains voltage fluctuation |
| Overvoltage/ Overcurrent 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 | To avoid frequently over current faults of the frequency inverter. |
| Torque Limit and Control | 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. |
| High Performance | Control of asynchronous motor and synchronous motor are implemented through the high-performance current vector control technology. |
