Abstract
A production machine includes an electrical positioning drive having a stator and a moveable member displaceable relative to the stator in at least one travel direction. The moveable member is mounted, in relation to the stator, in a contactless manner by a magnetic field in at least one of the supporting directions differing from the travel direction. A sensor device is associated with the positioning drive to shift the moveable member relative to the stator in the supporting direction to be detected. A control device is also associated with the positioning drive, and the shift of the moveable member is detected by the sensor device and can be supplied in the supporting direction. A control signal for a positioning magnet system can be determined by the control device, on the basis of the shift of the moveable member in the supporting direction and a nominal positioning of the moveable member. The positioning magnet system can monitor the positioning of the moveable member in relation to the stator in the supporting direction in a non-contact manner. The control signal can be emitted to the positioning magnet system by the control device.
