    • The present invention relates to a frequency converter (1) comprising a memory (M1) for storing data; a controller (8) for controlling the operation of the frequency converter by utilizing data (DATA1) stored in the memory (M1); and an interface (10) for connecting the frequency converter to other frequency converters. For efficient and simple backuping and restoration of the backup copy, the frequency converter comprises a backup application (9) for backuping the data (DATA1) stored in the memory (M1) of the frequency converter by retrieving data stored in the memory of the frequency converter and by transmitting the data retrieved over the interface (10) to at least one other frequency converter for storage in a memory (M2, M3) of said at least one other frequency converter; and maintains a backup copy (DATA2, DATA5) of at least one other frequency converter by storing the data received over the interface (10) from said at least one other frequency converter in the memory (M2, M3).
    • 本发明涉及一种包括用于存储数据的存储器(M1)的频率转换器(1) 控制器(8),用于通过利用存储在存储器(M1)中的数据(DATA1)来控制变频器的操作; 和用于将变频器连接到其他变频器的接口(10)。 为了有效且简单地备份和恢复备份副本,变频器包括用于通过检索存储在频率存储器中的数据来备份存储在变频器的存储器(M1)中的数据(DATA1)的备份应用程序(9) 并通过将通过接口(10)检索的数据传输到至少一个其他变频器以存储在所述至少一个其他变频器的存储器(M2,M3)中; 并且通过将通过接口(10)从所述至少一个其他频率转换器接收到的数据存储在存储器(M2,M3)中,保持至少一个其他频率转换器的备份副本(DATA2,DATA5)。
