First Claim
1. An industrial machine comprising:
- a dipper;
a crowd motor drive configured to provide one or more control signals to a crowd motor, the crowd motor 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 motor drive, the controller configured tomonitor a characteristic of the industrial machine,identify an impact event associated with the dipper based on the monitored characteristic of the industrial machine, andset a crowd motoring torque limit for the crowd motor drive when the impact event is identified.
