Zusammenfassung: | The invention provides controlling shoveling parameters of an industrial machine. An industrial machine that includes a dipper, a dipper handle, a boom, a shoveling 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 shoveling motor is set to a maximum value. If the retract torque is less than the threshold value, the retract torque of the shoveling motor is set to a default value. |
