| Onboard multiple preset speeds | It implements up to 16 speeds via the simple PLC function or combination of DI terminal states. | ||
| Onboard PID | It realizes process-controlled closed loop control system easily. | ||
| Auto voltage regulation (AVR) | It can keep constant output voltage automatically when the mains voltage changes. | ||
| Overvoltage/ Overcurrent stall control | The current and voltage are limited automatically during the running process so as to avoid frequent tripping due to overvoltage/overcurrent. | ||
| Fast current limit function | Minimize the over-current fault,and protect the normal operation of the AC drive. | ||
| Torque limit and control | It can limit the torque automatically and prevent frequent over current tripping during the running process. Torque control can be implemented in the CLVC mode. | ||
| Individualized functions | High performance | Control of asynchronous motor and synchronous motor are implemented through the high-performance current vector control technology. | |
| Power dip ride through | The load feedback energy compensates the voltage reduction so that the AC drive can continue to run for a short time. | ||
