| PLC,Multiple preset speeds | It implements up to 16 speeds via the simple PLC function or by input(X) terminal states |
| Built-in 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. |
| Over-voltage/
Over-current stall
control | The current and voltage are limited automatically during the running process so as to avoid frequent tripping due to over-voltage/over-current. |
| Torque limit and
control | It can limit the torque automatically and prevent frequent over-current tripping during the running process. |
| High performance | Control of asynchronous motor is implemented through the high-performance current vector control technology |
| Instantaneous blackout doesn’t stop | The load feedback energy compensates the voltage reduction so that the AC drive can continue to run for a
short time. |
