Excellent Performance  Control Mode  Vector Control 1 ： Offering excellent vector control performance and insensitive to motor parameters. Startup torque: 0.50Hz 180% rated torque Speed adjustment range: 1:100 Speed stabilization precision: ± 0.5% 0.50Hz controlble motor stable operation with 150% rated torque  Vector Control 2 ： Precise speed sensorless vector control technology realizes AC motor decoupling, enabling the DC motorization of operation control. Startup torque: 0.25Hz 180% rated torque Speed adjustment range: 1:200 Speed stabilization precision: ± 0.2%  Excellent Control Performance under Speed Sensorless Vector Control Mode  Realizing AC motor decoupling, enabling the DC motorization of operation control.  Fig. 1 indicates the four-quadrant operation of the motor under speed sensorless vector control. The torque, current, speed and DC bus voltage have quick response, and the motor has stable operation.  Realizing 0.1s acceleration/deceleration with rated motor load.  Upon the zero-crossing switching of the motor (forward/reverse switching), the current has no phase mutation or oscillation, and the rotating speed has no pulsation.  The bus voltage is under stable control.
