Abstract: A method of controlling a digging operation of an industrial machine. The industrial machine includes a dipper, a hoist rope attached to the dipper, a hoist motor moving the hoist rope and the dipper, and a computer having a controller. The method includes monitoring a speed of the hoist motor, determining an acceleration rate of the hoist motor, comparing the acceleration rate of the hoist motor to a threshold reverse factor, determining an impact situation when the acceleration rate is less than the threshold reverse factor, and sending a reverse torque control command signal to the hoist motor.

Abstract: An industrial machine that includes a dipper, a dipper handle, a boom, a crowd motor, a hoist motor, a swing motor, a first sensor, a second sensor, and a controller. The first sensor generates a first signal related to a dipper handle angle and the second sensor generates a second signal related to a hoist rope angle. The first signal and the second signal are received by the controller. The controller determines, based on the first and second signals, a retract torque value. The retract torque value is compared to a retract torque threshold values. If the retract torque value is greater or equal to the threshold value, the retract torque of the crowd motor is set to a maximum value. If the retract torque is less than the threshold value, the retract torque of the crowd motor is set to a default value.

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.

Abstract: Controlling a digging operation of an industrial machine. The industrial machine includes a dipper, a crowd motor, and a hoist motor. The control includes determining a torque associated with the crowd motor and a torque associated with the hoist motor and determining a dig force vector for the dipper based on the torque associated with the crowd motor and the torque associated with the hoist motor. The dig force vector includes a dig force angle and a dig force magnitude. The method also includes determining a value for the dig force angle of the dig force vector, and controlling, using a processor, the dig force magnitude based on the determined value for the dig force angle. The dig force magnitude is controlled by controlling at least one of the torque associated with the crowd motor and the torque associated with the hoist motor.

Abstract: A controller that includes a memory and an electronic processor. The electronic processor receives a first signal and a second signal. The electronic processor determines a retract torque limit based on the first signal and the second signal. The electronic processor sets a retract torque parameter of a crowd motor to the retract torque limit that has been determined. The electronic processor operates the crowd motor at or below the retract torque parameter.
