A control device for industrial machines with controlled motion drives for machine components has at least one operating element which is configured to manually influence or set adjustment movements of the machine components and which is designed as a rotary actuator operating element comprising a continuously rotatable actuating member. The rotary actuator operating element and a push-button element are connected to an electronic evaluation and control device which is configured to provide two interactive modes. The first interactive mode sets a movement speed and a desired movement direction of a machine component to be controlled and the push-button must be actuated or activated and simultaneously or additionally the actuating member of the rotary actuator operating element must be adjusted. In the second interactive mode a rotary actuation member is enabled without simultaneous actuation of the push-button element.
