摘要

The drive device comprises two drive controllers (1-n), particularly a static frequency changer, which is provided with an interface. The drive controllers have another interfaces (3,4), where both the interfaces are Ethernet interfaces. The drive controllers and a network are connected together by the network cables (6), which are connected to the Ethernet interfaces.
