Systems, methods, and devices for controlling an industrial machine. The industrial machine includes, for example, a dipper, a boom, a hoist motor, a crowd motor, one or more operator control devices, and a controller. The control devices are configured to be manually controllable by an operator of the industrial machine. The controller receives an output signal associated with a desired movement of the dipper, receives a signal associated with a hoist motor characteristic, and receives a signal associated with a crowd motor characteristic. The controller determines a present position of the dipper with respect to a boom profile, determines a first future position of the dipper with respect to the boom profile and based on the output signal from the operator control devices, and automatically controls a movement of the dipper with respect to the boom profile when the first future position of the dipper approximately corresponds to a boom profile limit.
An industrial machine comprising:
A method of controlling an industrial machine, the industrial machine including a dipper, a boom having a boom profile and a boom profile limit, a hoist motor having a hoist motor characteristic and configured to receive control signals from a hoist drive module, a crowd motor having a crowd motor characteristic and configured to receive control signals from a crowd drive module, one or more operator control devices configured to be manually controllable by an operator of the industrial machine, and a controller connected to the one or more operator control devices, the hoist drive module, and the crowd drive module, the method comprising:
