0.75KW~630KW, 220VAC~690VAC. 
Excellent control performance in sensorless vector control mode.
a). Four-quadrant operation of the motor in sensorless vector control mode . The torque ,current ,spinning speed and DC bus voltage have quick response ,and the motor has stable operation.
b). 0.1 s acceleration/deceleration is available with rated motor load.
c). During forward and reverse running, the current and speed will keep stable.
d). Quick and reliable braking can be get when deceleration with braking unit.
Large torque at low speed stable operation under vector control
a.) Start torque : 0.5Hz can get 150% torque ( sensorless vector control mode ).
0.0Hz can get 180% output torque (sensor vector control mode).
b.)Speed stabilization accuracy: sensorless vector control mode (without PG feedback):≤±0.5%,
sensor vector control mode ( with PG feedback ) vector control mode : ≤±0.2%
2. Support sensorless vector control, V/F control, sensorless open/closed loop vector
Multi-function with simple operation
2. Various external interfaces and swappable terminal broad convenient for replacement and maintenance.
1). Encoder expansion card (PG card) ,it is necessary part for the inverter closed-loop vector control.
