Abstract

Control arrangement for an electric motor having a control arrangement which, in accordance with at least one nominal value fed thereto, controls at least one power control element to be connected to an electrical network and the motor, including data transmission apparatus in the form of a computer device for applying to the control arrangement data received by the computer device from at least one of a device for determining the data and a memory wherein the data are stored.

Claims

1. A combination comprising a control arrangement, at least one electric motor connected to a machine which, in accordance with at least one nominal value fed thereto, controls at least one power control element, connected to an electrical network and the electric motor, data transmission means in the form of a computer device for applying to the control arrangement data received by the computer device from a memory wherein the data are stored;

wherein said memory has means for containing parameters of a plurality of different motors, and including means for entering the type of the at least one electric motor and the machine, and parameter selecting means for selecting said parameters.

2. The combination according to claim 1, including means for manually entering said data.

3. Control arrangement assembly according to claim 1, including coding plugs by means of which at least one of the connected electric motor and the machine driven by the motor is recognized.

4. Control arrangement assembly according to claim 3, wherein said coding plugs are connected to at least one of measuring lines and control lines leading to at least one of the connected electric motor and the machine driven by the connected electric motor.

5. Control arrangement assembly according to claim 1, including a measuring device for determining at least one characteristic measurement value, means for recognizing from said measurement value at least one of the connected electric motors connected to the control arrangement and the machine driven by the connected electric motor.

6. Control arrangement assembly according to claim 1, including a code system scannable via a line for recognizing at least one of the connected electric motor connected to the control mechanism and the connected machine.

7. Control arrangement assembly according to claim 1, including a monitoring device for feeding to the control mechanism a modified value for at least one of the data values and parameters upon the occurrence of a predetermined operational behavior of the connected electric motor of the control assembly.

8. Control arrangement assembly according to claim 1, for controlling an externally excited DC connected electric motor, comprising means for setting the exciter current to such a value, based upon at least one of the data and parameters and, if necessary, upon measurement values determined in the control arrangement during operation of the connected electric motor, that a prescribed operational behavior exists and is kept constant at this value.

9. Control arrangement assembly according to claim 1, wherein said memory has means for containing therein parameters of said current converter for supplying energy to the connected electric motor, said parameters being evaluatable by the control arrangement.

10. Control arrangement assembly according to claim 1, wherein said memory is a digital memory.

11. Control arrangement assembly according to claim 10, wherein said digital memory is a ROM.

12. A combination comprising a control arrangement, at least one electric motor connected to a machine which, in accordance with at least one nominal value fed thereto, controls at least one power control element connected to an electrical network and said electric motor, data transmission means in the form of a computer device for applying to said control arrangement data received by said computer device from a memory wherein said data are stored;

wherein said memory has means for containing parameters of a plurality of different power control elements, and including means for entering the type of said power control element, and parameter selecting means for selecting said parameters.

13. Control arrangement assembly according to claim 12, wherein data regarding the connected power control element is introducible manually via an input device.

14. Control arrangement assembly according to claim 12, including coding plugs by means of which the connected power control element is recognized.

15. Control mechanism assembly according to claim 12, including a measuring device for determining at least one characteristic measurement value so as to recognize the connected power control element.

16. Control arrangement assembly according to claim 12, including a code system scannable via a line for recognizing the connected power control element.
