Arrangement and method for an electric machine
First Claim
1. A system comprising:
- an electric machine;
memory means for storing information concerning the electric machine and fixedly attached in connection with the electric machine;
at least one control unit adapted to control the operation of the electric machine;
and interface between the memory means and said at least one control unit so that said at least one control unit is enabled to read the information stored in the memory means, wherein the control unit is arranged to process the information read from the memory means such that the information becomes verified with default parameters of the system after read-out thereof, and in case the information includes parameters which do not match in a predefined manner with the default parameters, the control unit is arranged to either automatically adjust the system in accordance with the information received from the memory means or to prevent start-up of the electric machine or the entire system.

Abstract
A system having an electric machine, memory device for storing information concerning the electric machine and is attached to the electric machine, and at least one control unit for controlling the operation of the electric machine. Furthermore, the system of the present invention has an interface between the memory device and the at least one control unit so that the at least one control unit reads the information stored in the memory device. The control unit processes the information read from the memory device such that the information becomes verified with default parameters of the system after read-out-thereof. In case the information includes parameters, which do not match in a predefined manner with the default parameters, the control unit is arranged to either automatically, adjust the system in accordance with the information received from the memory device or to prevent start-up of the electric machine or the entire system.

16. A method of installing an electric machine to a system, said system comprising control means controlling the operation of the electric machine when the electric machine is installed in the system, the method comprising:
-
storing information relating to the electric machine in a memory means attached in connection with the electric machine;
reading at least a part of the information stored to the memory means by the control means via an interface between the memory means and the control means;
comparing the read information with default parameters to ensure that the electric machine can be used in the system; and
in case the read information includes parameters which do not match in a predefined manner with the default parameters either automatically adjusting the control means and/or the system in accordance with the read information or preventing the electric machine and/or system to be started. - View Dependent Claims (17, 18, 19)
