Simple PLC,multi-stange running | It can perform running at 8-stage speed through built-in PLC or control terminals | ||||||
Bulit-in PID | Easy to form program control loop control system | ||||||
Auto voltage regulation(AVR) | When system voltage change, able to keep output voltage constant automatically | ||||||
Compensation of rotation error | Rational setting of compensation for rotation error, can compensate the change of rotation speed due to load, to achieve higher control accuracy of speed | ||||||
Auto limiting current | Limit the operation current, prevent frequently tripping due to over-current | ||||||
Control of over-voltage speed loss | Limit the operation voltage, prevent frequently tripping due to over-voltage | ||||||
Magnetic flux braking | To achieve shorter speed-down/braking time through this mode | ||||||
Over-modulation | Utilize over-modulation technology for over the basic freq, to get higher voltage output, increase hi-freq output torque of the motor. | ||||||
No stop at instantaneous | When voltage fall down at short time, it can keep inverter busbar voltage constant, to avoid tripping. |
