Configuration of a frequency converter
View Patent ↗A configuration tool for configuring a frequency converter includes an interface with connector poles for connecting the configuration tool to the frequency converter and feeding configuration data from the configuration tool to the frequency converter. To facilitate the configuration of an unelectrified frequency converter, the configuration tool includes a battery or an electromagnetic field generator for conveying the energy required for electrifying at least the memory of the frequency converter to the frequency converter during the configuration.
1. A method of configuring an unelectrified frequency converter having a memory and an input for electrifying by connecting the frequency converter to an electric network and an interface with connector poles for connection of a configuration tool, comprising
connecting a configuration tool to the frequency converter by connecting connector poles of the configuration tool to the connector poles of the interface,
electrifying at least the memory in the frequency converter with the configuration tool and by means of said connector poles of the configuration tool and the connector poles of the interface for a period of configuration; and
feeding by means of the connector poles of the configuration tool and the interface configuration data to the memory in the frequency converter electrified with the configuration tool.
2. The 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 input for electrifying by connecting the frequency converter to an electric network,
an interface for connecting a configuration tool to the frequency converter, whereby said interface is a wired interface including connector poles shaped to be connected to connector poles in the configuration tool for a period of configuration, during which configuration data is received from the configuration tool and stored in said memory, and at least said memory is electrified for said period of configuration by utilizing energy conveyed from the configuration tool via said connector poles; 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 configuration tool for configuring a frequency converter having an input for electrifying by connecting the frequency converter to an electric network, which configuration tool comprises an interface for connecting the configuration tool to the frequency converter, said interface is a wired interface including connector poles shaped to be connected to connector poles in an interface of the frequency converter for a period of configuration, during which configuration data is fed from the configuration tool to the frequency converter and stored in a memory of the frequency converter, and energy required for electrifying at least the memory of the frequency converter is conveyed from the configuration tool via the connector poles to the interface of the frequency converter during the period of configuration.
5. The configuration tool according to claim 4 , wherein said configuration tool is a portable configuration tool including a battery for conveying said energy to the frequency converter.
