|
| Built in PLC, multiple speeds | 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 automaticaly when the main 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 trpping | |
| 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. |
