Abstract

An electronic intermediate module for acquiring data from at least one peripheral unit, and for transmitting the acquired data to a position measuring device, the electronic intermediate module including a data acquisition interface for a data transmission connection which is designed for transmitting first data from the peripheral unit in a direction toward the electronic intermediate module. The electronic intermediate module further including a communications interface for a communications connection, wherein the communications connection is designed for transmitting second data from the intermediate module to the position measuring device.

Claims

1. An arrangement for regulating an electrical drive, the arrangement comprising:

a peripheral unit;

an electronic intermediate module connected to said peripheral unit via a data acquisition interface and a data transmission connection;

a position measuring device that provides position data of a movable element for regulating purposes, said position measuring device is connected with said electronic intermediate module via a first communications interface and a first serial communications connection, wherein first data which is not time critical is transmitted from said peripheral unit to said electronic intermediate module via said data transmission connection and second data which is not time critical is transmitted from said electronic intermediate module to said position measuring device via said first serial communications connection, wherein said position measuring device further comprises a second communications interface; and

a control unit being connected to said position measuring device via said second communications interface and a second serial communications connection via which said position data and said second data is transmitted and wherein said control unit uses said position data and said second data for regulating said electrical drive.

2. The arrangement in accordance with claim 1, wherein said first data comprises analog data and said data acquisition interface is designed for transmitting said analog data between said peripheral unit and said intermediate module.

3. The arrangement in accordance with claim 2, wherein said electronic module further comprises an A/D conversion unit for digitizing said analog data transmitted from said peripheral unit.

4. The arranaement in accordance with claim 1, wherein said electronic module further comprises a signal processing unit for processing said first data transmitted from said peripheral unit.

5. The arrangement in accordance with claim 1, wherein said electronic module further comprises a signal processing unit, which is suited for processing said first data transmitted from said peripheral units for serial transmission via said communications interface.

6. The arrangement in accordance with claim 1, wherein said data acquisition interface is designed for serial transmission of data between said peripheral unit and said intermediate module.

7. The arrangement in accordance with claim 1, wherein said communications interface is designed for serial transmission of data via said first communications connection.

8. The arrangement in accordance with claim 1, wherein said first data is processed by said electronic intermediate module into said second data which is different than said first data.

9. The arrangement in accordance with claim 1, wherein said peripheral unit comprises a sensor for detecting measured values which are not time-critical.

10. The arrangement in accordance with claim 9, wherein said peripheral unit comprises a temperature sensor.

11. The arrangement in accordance with claim 9, wherein said peripheral unit comprises a memory unit.

12. The arrangement in accordance with claim 11, wherein specific data regarding said position measuring arrangement are stored in said memory unit.

13. The arrangement in accordance with claim 1, wherein said electronic intermediate module comprises a plurality of data acquisition interfaces.

14. The arrangement in accordance with claim 13, wherein said plurality of data acquisition interfaces are distinct from each other.

15. The arrangement in accordance with claim 1, further comprising a temperature sensor that detects a winding temperature of said electrical drive.

16. The arrangement in accordance with claim 1, wherein said peripheral unit comprises an acceleration sensor.
