Technical Advantage
Control mode
(1) VF control: Multipoint VF curve. This apply to the situation that one frequency inverter drives multiple motors, such as fan, water pump, engraving machine, injection molding machine etc.
(2) Open-loop vector control: Steady speed with high precision, wide range of speed governing, as the speed ratio is 1:150 and frequency is 0.5Hz, we could output 150% rated torque. Good dynamic performance.
