摘要（英）：

The invention discloses a control circuit, a control method and device and an electronic device. The control circuit comprises a first switch circuit which is used for triggering the generation of a fault signal when being disconnected, a second switch circuit, and a differential circuit. The input end of the second switch circuit is connected with the output end of the first switch circuit. When the first switch circuit is disconnected, the output end of the second switch circuit outputs high level. The enable end of the differential circuit is connected with the output end of the second switch circuit. The output end of the differential circuit is connected with the input end of a drive mechanism in a target device. The differential circuit is used to stop outputting a control signal to the drive mechanism when the output end of the second switch circuit outputs high level. According to the invention, the technical problem that the emergency stop of a motion control system cannot be controlled without outage in the prior art is solved.
