A position-measuring device includes: a first subassembly having a measuring standard on which at least one coded track is provided, and a scanning unit, which is able to generate position signals that may be used to generate an absolute digital position value by scanning the at least one coded track in a measuring direction; a second subassembly having at least one peripheral unit adapted to execute a supplementary or an auxiliary functionality of the position-measuring device; and a plurality of electrical lines, which connect the first subassembly and the second subassembly to each other for the transmission of electrical signals. The position-measuring device is able to be operated in an initialization mode and in a standard operating mode. All components of the first subassembly required for the operation in the standard operating mode are components that are suitable for use in a radiation region of a machine. Furthermore, an initialization memory is provided in the first subassembly, which includes the data required for the operation in the standard operating mode and which is not suitable for use in a radiation region of a machine. In the initialization mode, the content of the initialization memory is transmittable to a memory unit situated outside the radiation region. Only the content of the memory unit is used for the operation in the standard operating mode.

Absolute position-measuring device

In a device and a method for transmitting energy and data between a control unit and a position-measuring device via a line pair, the energy transmission takes place in a charge mode and the data transmission takes place in a communication mode, and an energy storage device is provided in the position-measuring device, which is able to be charged in the charge mode via the line pair, and which is able to supply energy to the position-measuring device in the communication mode, and a charge unit and a switching device are provided in the control unit. The switching unit is adapted to the charge unit to the line pair in two-pole manner.

A holding device for a scale including a support body, a first solid body link and a second body link. The first solid body link acts as a connection between a first longitudinal side of a scale and the support body, via which the scale can be seated, shiftable in a measuring direction, on the support body. The second solid body link acts as a connection between a second longitudinal side of the scale and the support body, via which the scale can be seated, shiftable in the measuring direction, on the support body, wherein the second longitudinal side and the first longitudinal side are arranged opposite each other.
