    Abstract: Systems, methods, devices, and computer readable media for controlling a digging operation of an industrial machine that includes a dipper and a crowd drive. A method includes determining an acceleration associated with the industrial machine, determining a crowd retract factor based on the acceleration, comparing the crowd retract factor to a threshold crowd retract factor, setting a crowd speed reference and a crowd retract torque for the crowd drive for a period of time based on the comparison of the crowd retract factor to the threshold crowd retract factor.

    Abstract: A mining machine includes a base, a boom, a member, and a dipper. The base includes a frame portion that is rotatable relative to the support surface about a machine axis. The boom includes a first end coupled to the base, a second end opposite the first end, and a sheave coupled to the second end of the boom. A first distance is defined between the machine axis and the second end of the boom. The member is movably coupled to the boom about a pivot point that is positioned substantially between the first end and the second end of the boom. A second distance is defined between the machine axis and the pivot point. A ratio of the second distance to the first distance is between 27% and 43%. The dipper is coupled to an end of the member and is supported by a hoist rope.

    Abstract: Controlling a digging operation of an industrial machine that includes a dipper, a crowd motor drive, and a controller. The crowd motor drive is configured to provide one or more control signals to a crowd motor, and the crowd motor is operable to provide a force to the dipper to move the dipper toward or away from a bank. The controller is connected to the crowd motor drive and is configured to monitor a characteristic of the industrial machine, identify an impact event associated with the dipper based on the monitored characteristic of the industrial machine, and set a crowd motoring torque limit for the crowd motor drive when the impact event is identified.
