Abstract

The invention relates to a configuration tool for configuring a frequency converter, which configuration tool comprises an interface for connecting the configuration tool to the frequency converter, said interface comprising means for feeding configuration data from the configuration tool to the frequency converter. To facilitate the configuration of an unelectrified frequency converter, said interface further comprises means for conveying the energy required for electrifying at least the memory of the frequency converter from the configuration tool to the frequency converter during the configuration.

Claims

1. A method of configuring an unelectrified frequency converter, comprising

connecting a configuration tool to the frequency converter,

electrifying at least a memory included in the frequency converter with the configuration tool for the period of configuration;

and

feeding configuration data to the memory electrified with the configuration tool.

2. A method according to claim 1, wherein said configuration data includes at least one of the following:

parameters, application macros or program code.

3. A frequency converter comprising

a memory;

an interface for connecting a configuration tool to the frequency converter, whereby said interface comprises means for receiving configuration data from the configuration tool and for storing the configuration data to said memory, and means for electrifying at least said memory by utilizing energy conveyed from the configuration tool; and

a control circuit arranged to utilize the configuration data stored in said memory to control the operation of the frequency converter in the way indicated by the configuration data.

4. A frequency converter according to claim 3, wherein said interface is a wireless interface including means for recovering energy from a surrounding electromagnetic field and for electrifying said memory by utilizing said recovered energy;

and means for receiving the configuration data wirelessly.

5. A frequency converter according to claim 3, wherein said interface is a wired interface including connector poles shaped to be connected to connector poles in the configuration tool for electrifying said memory and for receiving the configuration data via said connector poles.

6. A configuration tool for configuring a frequency converter, which configuration tool comprises an interface for connecting the configuration tool to the frequency converter, said interface comprising means for feeding configuration data from the configuration tool to the frequency converter, and means for conveying energy required for electrifying at least the memory of the frequency converter from the configuration tool to the frequency converter during the configuration.

7. A configuration tool according to claim 6, wherein said configuration tool is a portable configuration tool including a battery for conveying said energy to the frequency converter.

8. A configuration tool according to claim 6, wherein said interface is a wired interface including connector poles shaped to be connected to connector poles in the frequency converter for conveying said energy to the frequency converter and for feeding the configuration data to the electrified memory of the frequency converter via said connector poles.

9. A configuration tool according to claim 6, wherein said interface is a wireless interface including means for generating an electromagnetic field in the surroundings of the configuration tool to convey the energy required for electrifying the memory of the frequency converter to the frequency converter;

and means for transmitting the configuration data via a wireless connection to the frequency converter.
