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.
