| Onboard multiple preset speeds | It implements up to 16 speeds via the simple PLC function or combination of 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/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 motor are implemented through the high-performance current vector control technology. | |
| Timing control | Time range: 0.0–6500.0 minutes | |
