The damping characteristics of Wideband Line Filters for Active Line Modules from 16 kW to 120 kW not only conform with the requirements of EMC standards for the frequency range of 150 kHz to 30 MHz, but also include low frequencies of 2 kHz and above. As a result, these line filters have an extended function area, as with the Active Interface Modules, which means that they can, to a certain extent, be used regardless of the machine installation location and any unknown line properties (e.g. line impedance).

For the Active Line Modules in booksize format, HFD packages (HFD line reactor incl. damping resistor) together with the Wideband Line Filters can be supplied as a functionally harmonized logistical unit ¹⁾.

Note:
Radio interference suppression is required in accordance with EMC standards (product standard IEC 61800-3, EN 61800-3; VDE 0160 T 100) and is mandatory due to guidelines (laws) in the EU. For this purpose, the separate and compact Active Interface Modules or the HFD packages (HFD line reactor and damping resistor) are required in combination with the Wideband Line Filter. The Wideband Line Filter with the HFD package forms a unit specially matched to the step-up converter principle of the Active Line Modules. Use of other filters can lead to exceeding of limit values, resonances, overvoltages and irreparable damage to motor or other equipment.

The HFD packages are used for SINAMICS S120 drive solutions that build on runtime versions below FW V2.5 SP1 (e.g. integrated automatic speed controls in SINUMERIK 802D sl/840D sl).
