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.
