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.

21. An industrial machine comprising:
-
a dipper; a crowd drive configured to generate one or more control signals for a crowd hydraulic actuator, the crowd hydraulic actuator being operable to provide a force to the dipper to produce a crowd motion; and a controller connected to the crowd drive, the controller configured to monitor a characteristic of the industrial machine, identify an impact event associated with the dipper based on a value of the monitored characteristic of the industrial machine, and set a crowd force value for the crowd hydraulic actuator based on the value of the monitored characteristic of the industrial machine when the impact event is identified. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method of controlling a digging operation of an industrial machine, the industrial machine including a dipper and a crowd drive, the method comprising:
-
monitoring, using a processor, a characteristic of the industrial machine; identifying, using the processor, an impact event associated with the dipper based on the monitored characteristic of the industrial machine, the impact event creating a tipping moment on the industrial machine; and setting, using the processor, a crowd force value for the crowd drive when the impact event is identified. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
