| Onboard multiple | It implements up to 16 speeds via the simple PLC function or combination of X terminal states | |
| Onboard PID | It realizes process-controlled closed loop control systerm easily | |
| Auto voltage regulation(AVR) | It can keep constant output voltage automatically when the main 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 frquent over current tripping during the running process | |
| Instantaneous stop doesn't stop | 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 performace | Control of asynchronous motor is implemented throgh the high-performance current vector | |
| Control technology | ||
