radial displacement sensorless operation 无径向位移传感器运行
The new three-phase drive control strategy SITRAC combines dynamic torque control, robustness and optimized modulation withselfadjustment and allows speed sensorless operation.
新的交流传动调节方法SITRAC融合动力学、耐用性和具有自调节的最佳调制为一体,其运行可不用速度传感器。
When the rotational frequency exceeds the forced commutation frequency specified with the status of the FST pins, the operation mode is switched to the sensorless mode.
当转动频率超过FST引脚状态指定的强制换向频率后,运行模式切换到无传感器运行模式。
