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.
