Abstract

In an inverter maintenance system, while an inverter of a user, a user support server of maker, and also, a portable telephone capable of accessing to a Web server are employed, such information required to maintain/manage the inverter is transferred/received by way of the portable telephone. Thus, various sorts of requests can be accepted by both the user support server and the Web server.

Claims

1. An inverter maintenance system wherein:

portable telephones having interfaces are employed in both an inverter of a user and a user support server of a maker;

said inverter maintenance system is comprised of;

a step in which when an abnormal condition of said inverter happens to occur, abnormal information of said inverter, which is inputted into said portable telephone, is transferred to said user support server; and

a step in which said user support server analyzes said abnormal information so as to form trouble shooting information, and then, transfers said formed trouble shooting information to said portable telephone; and

said abnormal condition of the inverter can be solved based upon the trouble shooting information transferred to said portable telephone.

3. An inverter maintenance system as claimed in claim 1 wherein:

said interface of the portable telephone is given by a program used to connect said inverter with said portable telephone.

5. An inverter maintenance system as claimed in claim 3 wherein:

said program is downloaded from a Web site of a maker to said portable telephone.

7. An inverter maintenance system as claimed in claim 1 wherein:

into said inverter, a parameter is entered from said portable telephone by manipulating a key thereof.

8. An inverter maintenance system as claimed in claim 7 wherein:

a program which is used to enter said parameter from said portable telephone into said inverter is downloaded from a Web site of a maker to said portable telephone.

9. An inverter maintenance system as claimed in claim 1 wherein:

said inverter maintenance system is comprised of;

a database into which when internal information of said inverter is received from said user support server, an acceptance ID is applied to a content at a time instant when said internal information is received, and then the acceptance ID-applied content is stored.

10. An inverter maintenance system as claimed in claim 1 wherein:

said inverter maintenance system is comprised of;

a function by which as a result of an automatic analysis by said user support server, when the abnormal condition of said inverter cannot be solved, the portable telephone is automatically connected to a support center operated by an operator.

12. An inverter maintenance system as claimed in claim 1 wherein:

said inverter is comprised of;

a function capable of displaying an internal parameter on said portable telephone.

14. An inverter maintenance system as claimed in claim 1 wherein:

said inverter is built in a motor which is controlled by said inverter.

16. An inverter maintenance system as claimed in claim 1 wherein:

said inverter is arranged by a group-of at least two inverters which are connected to each other via either a wire line or a wireless line.

18. An inverter maintenance system as claimed in claim 1 wherein:

said inverter maintenance system is comprised of;

a function by which a control program written into said inverter is downloaded from a server by employing a portable telephone to be rewritten.

2. An inverter maintenance system wherein:

a portable telephone having an interface is employed in a user support server of a maker;

the inverter maintenance system is comprised of;

a step in which inverter purchase request information entered into said portable telephone is transferred to said user support server; and

a step in which said user support server analyzes said inverter purchase request information so as to form inverter recommendable machine sort information, and transfers said formed inverter recommendable machine sort information to said portable telephone so as to prompt an input of inverter machine sort determination information; and

the inverter maintenance system can accept an inverter purchase request made by the user based upon said inverter machine sort determination information.

4. An inverter maintenance system as claimed in claim 2 wherein:

said interface of the portable telephone is given by a program used to connect said inverter with said portable telephone.

6. An inverter maintenance system as claimed in claim 4 wherein:

said program is downloaded from a Web site of a maker to said portable telephone.

11. An inverter maintenance system as claimed in claim 2 wherein:

said inverter maintenance system is comprised of;

a function by which as a result of an automatic analysis by said user support server, when the abnormal condition of said inverter cannot be solved, the portable telephone is automatically connected to a support center operated by an operator.

13. An inverter maintenance system as claimed in claim 2 wherein:

said inverter is comprised of;

a function capable of displaying an internal parameter on said portable telephone.

15. An inverter maintenance system as claimed in claim 2 wherein:

said inverter is built in a motor which is controlled by said inverter.

17. An inverter maintenance system as claimed in claim 2 wherein:

said inverter is arranged by a group of at least two inverters which are connected to each other via either a wire line or a wireless line.

19. An inverter maintenance system as claimed in claim 2 wherein:

said inverter maintenance system is comprised of;

a function by which a control program written into said inverter is downloaded from a server by employing a portable telephone to be rewritten.

20. An inverter operated by a parameter set in a control apparatus, wherein:

said parameter is constituted to be set by manipulating a key of a portable telephone.

21. An inverter as claimed in claim 20 wherein:

when the parameter is set by said portable telephone, said parameter is displayed on a display screen of said portable telephone.
