电机控制器与计数位置错误事件相抵触，电机控制方法采用相同方式

Motor controller having counter to count position error events and method of motor control using same
摘要：
A motor control system uses an incremental encoder that provides a signal indicative of motor position. If an illegal state change is detected in the same sampling interval, an error event is recorded and an error counter is incremented. When the number of counts exceeds a pre-determined threshold, the motor is disabled so that appropriate corrective action can be taken.
摘要（中）：

电机控制系统使用提供指示电机位置的信号的增量式编码器。 如果在相同的采样间隔内检测到非法状态改变，则会记录错误事件，并增加错误计数器。 当计数超过预定阈值时，电机被禁用，以便采取适当的纠正措施。
