Claims (1)
実際の速度を電圧として検出する速度検出器の出
力の一方を基準値、他方を比較値とし、前記基準
値に可変抵抗により任意の正及び負の電圧を与え
て上限値及び下限値を設定してそれぞれ比較器に
より前記比較値と比較して異常速度を検出するこ
とを特徴とする異常速度検出装置。 One of the output of the speed setter that sets the speed command voltage and the output of the speed detector that detects the actual speed as a voltage is used as a reference value, and the other is used as a comparison value. An abnormal speed detection device characterized in that an upper limit value and a lower limit value are set by applying a voltage, and the abnormal speed is detected by comparing the set upper limit value and lower limit value with the comparison value using a comparator.
