First Claim
Patent Images
1. An industrial machine comprising:
- a dipper;
a crowd drive configured to provide one or more control signals to a crowd actuation device, the crowd actuation device being operable to provide a force to the dipper to move the dipper toward or away from a bank; and
a controller connected to the crowd drive, the controller configured tomonitor a characteristic of the industrial machine,determine if a value of the monitored characteristic of the industrial machine is indicative of an impact event associated with the dipper, andset a crowd drive parameter for the crowd actuation device based on the value of the monitored characteristic of the industrial machine when the value of the monitored characteristic of the industrial machine is indicative of the impact event, wherein the crowd drive parameter for the crowd actuation device is related to a crowd force in response to the impact event,wherein the crowd drive is configured to provide the one or more control signals to the crowd actuation device based on the crowd drive parameter, andwherein the crowd actuation device generates the crowd force in response to the impact event, the generated crowd force being limited by the crowd drive parameter.

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.
