V/F curve | 21 modes: linear, 2 squared characteristic curve and V/F curve with multiple dots | ||||||
Speed up/down curve | Linear curve speed up/down: 2 kinds of speed up/down time, longest time: 1 hour | ||||||
DC braking | Startup freq of DC braking:0.00Hz~maxi freq, Braking time:0.0s~30.0s, braking current: 0.0~150.0% rated current of motor | ||||||
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 | ||||||
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. | ||||||
