1. An industrial machine comprising:
- a dipper;
a crowd drive configured to provide a control signal to a crowd actuator, the crowd actuator operable to provide a crowd force to the dipper to produce a crowd motion; and
a controller connected to the crowd drive, the controller configured todetermine a hoist force acting on the dipper,determine a crowd force limit value based on the determined hoist force, the crowd force limit value being determined as a function of the determined hoist force, andset a crowd force limit for the crowd drive to the determined crowd force limit value.
