    • The present invention is intended to provide a collimator control method that does not cause blades to get stuck. In a homing phase, blades are positioned based on a blade sense signal sent from a sensor. If the sensor has not sensed the blades but the rotational velocity of a motor has decreased to fall below a predetermined velocity, control states are switched. In a working phase, when an overshoot made by the blades returning to zero positions exceeds a predetermined limit, the control states are switched. Moreover, the rotating direction of the motor is reversed in order to withdraw the blades. Moreover, a collimator is reset to the control state based on tentative zero positions or the control state based on the sense signal sent from the sensor according to whether the sensor has failed.
    • 本发明旨在提供一种不会使刀片卡住的准直器控制方法。 在归位阶段,叶片基于从传感器发送的叶片感测信号定位。 如果传感器没有检测到叶片,但是马达的旋转速度已经降低到低于预定速度,则切换控制状态。 在工作阶段,当由叶片返回到零位置的过冲超过预定极限时,切换控制状态。 此外,电动机的旋转方向相反,以便抽出叶片。 此外,根据传感器是否发生故障,基于临时零位置或基于从传感器发送的感测信号的控制状态将准直仪复位到控制状态。
