Abstract
A machine has a frame structure for moving a machine head in one or more spatial directions. The frame structure comprises an actuator and an air bearing for moving the head. The machine also comprises a compressed air feed connected to the air bearing for providing a compressed air flow. A restrictor defines the compressed air flow to the air bearing. The machine has a first operating state, in which a high compressed air flow is defined and in which the actuator can be actuated. The machine has a second operating state, in which a compressed air flow lower than the high compressed air flow is defined. In the second operating state, the actuator is secured against actuation from a closed-loop position controller, while the closed-loop position controller is maintained in operation.
