The invention provides a loop sudden stop control circuit and a loop sudden stop control method. The circuit comprises a signal trigger circuit, a bypass switch, a signal output circuit, a logic control unit and an emergency stop output control circuit, the signal trigger circuit is respectively connected with the bypass switch and the signal output circuit, and the logic control unit is respectively connected with the signal trigger circuit, the bypass switch, the signal output circuit and the sudden stop output control circuit. By switching the bypass switch, sudden stop cannot be triggered when the loop trolley triggers the limit switch under the conditions of production line maintenance and the like, and by adopting the technical scheme provided by the invention, the sudden stop cannot be triggered when the loop trolley triggers the limit switch in an inching operation mode; when the loop trolley passes through the limit switch, a hard wire is needed to shield an emergency stop signal or the limit switch
