Abstract:
1. A method of controlling a digging operation of an industrial machine, the industrial machine including a component and a hoist motor drive, the method comprising: determining a first position of the component with respect to a digging envelope; determining, using a processor, a first hoist force setting based on the first position of the component and a relationship between component position and hoist force; setting, by the processor, a first level of hoist force for the hoist motor drive to the first hoist force setting; determining a second position of the component with respect to the digging envelope; determining, by the processor, a second hoist force setting based on the second position of the component and the relationship between component position and hoist force; and setting, by the processor, a second level of hoist force for the hoist motor drive to the second hoist force setting, wherein the first level of hoist force is greater than the second level of hoist force.
