Abstract: A control device for industrial machines having controlled motion drives for machine components has at least one control element configured to manually influence or specify adjustment movements of at least one machine component and is implemented as a rotary control element with a continuously rotatable actuating element connected in terms of motion to a rotational resistance generator that is variable under control or the actuating element can be connected in terms of motion thereto. The rotational resistance generator is drivable by an analysis and control device. The analysis and control device and the rotational resistance generator in this case are equipped to inhibit the rotational mobility of the actuating element, or to subject it to an increased rotational resistance haptically perceptible by an operator, as a function of machine states or events known to or sensed by the control device. In addition, a corresponding control method is specified.
