Abstract

Arrangement for connecting set values concerning performance relating to an electronics device to the electronics device, more particularly to a power electronics device, such as a frequency converter, which arrangement includes a rating plate part. The rating plate part is a separate unit belonging to the nameplate arrangement of the electronics device, which unit may be affixed to the electronics device. The rating plate part includes a memory member, in which values concerning the performance of the device are recorded. The rating plate part further includes an area in which information corresponding to the information recorded in the memory member is printed and which area remains visible when the rating plate part is affixed to the electronics device.

Claims

1. Arrangement for connecting set values concerning performance to an electronics device, more particularly to a power electronics device, a frequency converter, which arrangement comprises a rating plate part comprising:

the rating plate part is a separate unit belonging to a nameplate arrangement of the electronics device, which unit is adapted to be affixed to the electronics device, and

the rating plate part comprises a memory means, an EEPROM memory circuit, in which values concerning the performance of the electronics device are recorded, and

the rating plate part further comprises an area in which information corresponding to the values concerning performance that are recorded in memory are permanently registered in such a way that this information remains visible when the rating plate part is affixed to the electronics device,

wherein the rating plate part further comprises a communication means for the digital data transfer occurring with the electronics device, by the aid of which communication means the values concerning performance that relate to the electronics device is transferred from the rating plate part to the electronics device.

2. Arrangement according to claim 1, wherein data transfer between the communication means of the rating plate part and the electronics device is adapted to be performed via a wireline or wireless connection.

3. Arrangement according to claim 2, wherein the electronics device, in connection with which the rating plate part has been disposed, comprises a communication means, which is adapted to read or to receive the values contained by the memory means of the rating plate part.

4. Arrangement according to claim 2, wherein the arrangement is adapted to use in the data transfer between the rating plate part and the electronics device an encryption algorithm, which prevents the reading of the data with communication means other than those belonging to the system.

5. Arrangement according to claim 2, wherein the electronics device, in connection with which the rating plate part has been disposed, is adapted to adjust its own performance values to be according to the definitions it reads from the memory means.

6. Arrangement according to claim 2, wherein the electronics device is adapted to adjust its own performance values to be permanently according to the definitions it reads from the rating plate part in such a way that after reading them they can no longer be changed.

7. Arrangement according to claim 1, wherein the electronics device, in connection with which the rating plate part has been disposed, comprises a communication means, which is adapted to read or to receive the values contained by the memory means of the rating plate part.

8. Arrangement according to claim 7, wherein the arrangement is adapted to use in the data transfer between the rating plate part and the electronics device an encryption algorithm, which prevents the reading of the data with communication means other than those belonging to the system.

9. Arrangement according to claim 7, wherein the electronics device, in connection with which the rating plate part has been disposed, is adapted to adjust its own performance values to be according to the definitions it reads from the memory means.

10. Arrangement according to claim 1, wherein the arrangement is adapted to use in the data transfer between the rating plate part and the electronics device an encryption algorithm, which prevents the reading of the data with communication means other than those belonging to the system.

11. Arrangement according to claim 10, wherein the electronics device, in connection with which the rating plate part has been disposed, is adapted to adjust its own performance values to be according to the definitions it reads from the memory means.

12. Arrangement according to claim 1, wherein the electronics device, in connection with the rating plate part has been disposed, is adapted to adjust its own performance values to be according to the definitions it reads from the memory means.

13. Arrangement according to claim 1, wherein the electronics device is adapted to adjust its own performance values to be permanently according to the definitions it reads from the rating plate part-in such a way that after reading them they can no longer be changed.

14. Arrangement according to claim 1, wherein the arrangement further comprises a device frame of the electronics device and a control unit and

the permitted performance range for the electronics device is recorded in the control unit of the electronics device, and

the control unit is adapted to accept as its own performance values only those performance values read from the rating plate part that fall within the permitted performance range for the device frame.

15. Arrangement according to claim 1, wherein the arrangement comprises mechanical fittings on the electronics device and on the rating plate part that are compatible with each other and are adapted to affix the rating plate part permanently to a disposal location sunk into the wall of the electronics device.

16. Arrangement according to claim 1, wherein the arrangement further comprises connector parts and a data transfer connection forms between the electronics device and the rating plate part by means of the connector parts when the rating plate part is installed into its position.

17. Arrangement according to claim 1, wherein the rating plate part comprises a mounting base, e.g. a circuit board, to which the memory means, an EEPROM memory circuit, is fixed.

18. Arrangement according to claim 1, wherein the rating plate part is a remotely readable sticker, an RFID identifier, comprising an antenna and a memory, which sticker is adapted to be glued to the electronics device.

19. Arrangement according to claim 1, wherein the values concerning the performance of the electronics device that are contained by a rating plate part, which values remain visible when the rating plate part is affixed to the electronics device, are visibly marked on the outer surface of the rating plate part by stamping, printing or impressing.

20. Arrangement according to claim 1, wherein a value relating to the performance of the electronics device is the type marking, rated voltage or rated current of the device.
