異常検出装置
Document Type and Number:
Japanese Patent JP6743976
Kind Code:
B2
Abstract:
An abnormality detection device according to the present invention is provided with a drive control unit (16), a storage unit (15), a determining unit (18), a computing unit (19), a determining unit (20), and a detection unit (21). The determining unit (18) determines whether the difference between a torque command outputted from the drive control unit (16) and a first torque pattern is larger than a first threshold value. The determining unit (20) determines whether a fluctuation quantity computed by the computing unit (19) is larger than a second threshold value. In the cases where the determining unit (18) determined that the difference is larger than the first threshold value, and the determining unit (20) determined that the fluctuation quantity is larger than the second threshold value, the detection unit (21) detects an abnormality.
