| Onboard Multiple preset speeds |
It implements up to 16 speeds via the simple PLC function or by control terminal |
| Onboard PID |
It realizes process-controlled closed loop control system easily. |
| Auto voltage |
It can keep constant output voltage automatically when the mains voltage changes. |
| regulation (AVR) |
| Over-voltage/ |
The current and voltage are limited automatically during the running process so as to avoid frequent tripping due to over-voltage/over-current. |
| Over-current stall control |
| Torque limit and torque control |
It can limit the torque automatically and prevent frequent 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 performance |
Control of asynchronous motor is implemented through the high-performance current vector control technology. |
