Taking a parameter backup requires a working connection between Danfoss Editron inverter and a computer, please see 'Connecting to a Danfoss Editron inverter'.
Choose 'Parameter tools' tab and click 'Backup device'. From there a desired location for the backup file can be chosen. Make sure the 24 V supply is not disrupted during the download process.
In case the backup fails, please make sure you have the latest PowerUSER software installed and try saving the file to a different folder, using a different filename, or take the backup with another computer.
