    • The invention relates to a mechanism wherein a relative rotary angle of a driving motor is detected by use of an encoder, and, if an error occurs in a servo control action when the driving motor is servo-controlled in accordance with a deviation value of the relative rotary angle from a desired rotary angle of the driving motor, then the servo control action is brought to an emergency stop. A potentiometer for detecting an absolute rotary angle of the driving motor is connected to a rotary shaft of the driving motor and said emergency stop is effected when a difference between said absolute rotary angle and said relative rotary angle exceeds a preset tolerance value, so that an error in the servo control action can be reliably prevented.
    • 本发明涉及一种机构,其中通过使用编码器来检测驱动马达的相对旋转角度,并且如果当驱动马达根据伺服控制的偏差值进行伺服控制时在伺服控制动作中发生错误 相对旋转角度从驱动马达的所需旋转角度,然后使伺服控制动作进行紧急停止。 用于检测驱动电动机的绝对旋转角度的电位器连接到驱动电动机的旋转轴,当所述绝对旋转角度和所述相对旋转角度之间的差超过预定公差值时,进行紧急停止, 可以可靠地防止伺服控制动作的误差。
