Q9000 Series is a kind of high performance universal vector control inverter. Current vector technology and advanced modern control theory are used to provide more torque in operation at low speed and achieve high performance dynamic control. There are four control modes to select. Even without PG vector control, it can obtain a high torque and failure-free operation from a low speed at 1%; While with PG control, it can easily obtain high torque operation at 0 speed, which is the ideal choice for you to improve the quality and productivity.
