Claims

[Scope of utility model registration request]

an incremental encoder in which the order in which two types of pulses are generated changes depending on the rotation direction;
means for receiving the two types of pulses and detecting the rotational direction of the incremental encoder based on the order of generation; means for receiving the two types of pulses and detecting the rotational speed of the incremental encoder; and detecting the rotational direction. Decide whether to increase or decrease the set value according to the signal from the rotational speed detection means, and when the signal from the rotational speed detection means indicates that the speed is fast, change the set value largely and change the setting above when the signal indicates that the speed is slow. A setting device comprising a setting value changing means for changing a value to a smaller value.
