Abstract:
An industrial machine that includes a dipper, a user interface, a sensor, a hoist actuator, and a controller. The user interface is operable to generate a first signal related to a requested characteristic of the industrial machine. The sensor is operable to generate a second signal related to an actual characteristic of the industrial machine. The hoist actuator has at least one operating parameter. The controller is configured to receive the first signal related to the actual characteristic, receive the second signal related to the requested characteristic, compare the requested characteristic to the actual characteristic to detect a dipper drop condition, and modify a setting of the at least one operating parameter of the hoist actuator after the dipper drop condition is detected. The dipper drop condition is detected after the requested characteristic does not match the actual characteristic
