  4. The rotating speed of motor can be measured by Hall sensor which is built in motor.
    1. In case the motor speed is lower than target value: Motor torque increases.
    2. In case the motor speed is faster than target value: Motor torque decreases.

      * If motor has restriction force during closing, it may be opened by repulsive force

  5. E-Latch contacts with the power striker shaft, and then E-Latch is locked mechanically. (Unlock → Lock)
