It realizes up to 16 speeds via the simple PLC function or combination of DI terminal states | |
| Built-in PID | It realizes closed loop control system easily. | |
| Auto voltage regulation (AVR) |
It can keep constant output voltage automatically when the mains voltage fluctuation. | |
| Overvoltage/ Over current stall control | The current and voltage are limited automatically during the running process so as to avoid frequently tripping due to overvoltage/over current. | |
Rapid current limit function | It can auto limit running current of frequency inverter to avoid frequently tripping. | |
Torque limit and control | (Excavator characteristics) It can limit the torque automatically and prevent frequently over current tripping during the running process. Torque control can be implemented in the VC mode. |
