Abstract: A system for controlling the operation of an industrial machine during crowd runaway conditions. The system includes a controller that monitors and compares an actual crowd system state (e.g., an actual dipper position) with a requested crowd system state (e.g., a requested dipper position from the operator). If the controller determines that the crowd system is behaving contrary to requested crowd system behavior, the controller adjusts a crowd parameter, such as a crowd motor torque, to resolve the runaway condition.

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.

Abstract: An industrial machine that includes a dipper, a hoist drum, a wire rope connected between the hoist drum and the dipper, a hoist motor, a sensor, and a controller. The sensor generates a signal related to a number of wire wraps of the wire rope around the hoist drum, which is received by the controller. The controller determines, based on the signal from the sensor, the number of wire wraps around the hoist drum. If the controller determines that there are an insufficient number of dead wraps around the hoist drum, the controller sets one or more parameters of the hoist motor. The controller sets each of the one or more parameters of the hoist motor to a value that is lower than a normal operational value for the parameter.

Abstract: Systems and methods for compensating dipper swing control. One method includes, with at least one processor, determining a direction of compensation opposite a current swing direction of the dipper and applying the maximum available swing torque in the direction of compensation when an acceleration of the dipper is greater than a predetermined acceleration value. The method can also include determining a current state of the shovel and performing the above steps when the current state of the shovel is a swing-to-truck state or a return-to-tuck state. When the current state of the shovel is a dig-state, the method can include limiting the maximum available swing torque and allowing, with the at least one processor, swing torque to ramp up to the maximum available swing torque over a predetermined period of time when dipper is retracted to a predetermined crowd position.

Abstract: An industrial machine and a method of controlling an industrial machine, the industrial machine including a dipper supported by a dipper handle. The method may include determining an operating phase of the industrial machine, in a first operating phase of the industrial machine, limiting, with at least one controller, a reach of the dipper handle, and in a second operating phase of the industrial machine, enabling, with the at least one controller, an extended reach of the dipper handle greater than the reach in the first operating phase. The industrial machine may include at least one controller configured to determine an operating phase of the industrial machine, in a first operating phase of the industrial machine, limit a reach of the dipper handle, and, in a second operating phase of the industrial machine, enable an extended reach of the dipper handle greater than the reach in the first operating phase.
