| 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-contolled closed loop control system easily. |
| Auto Voltage Regulation (AVR) | It can kep 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 overvolatge/over Current. |
| Torque limit & 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. |
| Rapid Current Limit | It helps to avoid frequent over current faults of the AC drive. |
