| Onboard multiple preset speeds | It implements up to 16 speeds via the simple PLC function or combination of termial states. | ||
| Onboard PID | It realized 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 / over current | ||
| Torque limit and control | It can limit the torque automatically and prevent frequent over current tripping during the running process. | ||
| 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. | ||
| Rapid current limit | It helps to avoid frequent over current faults of the AC drive. | ||
| High performance | Control of asynchronous motoris implemented through the high-performance current vector control technology. | ||
