Abstract
A method of controlling a digging operation of an industrial machine. The industrial machine includes a dipper connected to a dipper handle, a hoist rope attached to the dipper, and a hoist motor moving the hoist rope and the dipper. The method includes determining that the dipper is ready to be unloaded, activating a secondary tipping control operation by controlling a speed of the hoist motor, controlling an acceleration ramp rate of the hoist motor, and controlling a deceleration ramp rate of the hoist motor. The method further includes determining when the dipper is unloaded and deactivating the secondary tipping control operation.
