HFD line reactor and damping resistor

As an alternative to the Active Interface Modules, a solution is also possible using an HFD line reactor package as a line connection for the Active Line Modules. The line reactors with HFD characteristics and damping resistor can be ordered in the form of an HFD package or as an HFD package in combination with line filters and are necessary for the function of the Active Line Modules.

The HFD packages are used with SINAMICS S120 drive solutions that build on runtime versions below FW V2.5 SP1 (e.g. integrated drive controls in SINUMERIK 802D sl/840D sl). The use of other makes of line reactor can lead to malfunctions or irreparable damage to equipment.
