VFD vs Servo Drive: Key Differences
A side-by-side comparison of VFD and servo drive motor type, feedback, dynamic response, overload rating, cost, and applications for industrial engineers.
The Siemens SINAMICS S120 Active Interface Module (6SL3100-0BE28-0AB0) conditions the 3 AC 380-480 V line supply for an 80 kW SINAMICS S120 Active Line Module, rated for 128 A input current with an IP20/UL open-type enclosure. It weighs 31.9 kg, dissipates 0.49 kW of losses, and is cooled by 0.167 m³/s of internal forced air at a sound pressure level of 68 dB.
This Active Interface Module is sized specifically for the 80 kW Active Line Module in the SINAMICS S120 modular system - match it 1:1 to that line module rather than a smaller or larger rating, since the 128 A input current and integrated line filter function are set for that power class. The IP20/UL open-type rating means it still needs a cabinet enclosure to provide the final environmental protection.
Filters and interfaces the incoming 3 AC 380-480 V line supply for a SINAMICS S120 Active Line Module in a modular multi-axis drive system, typically in machine tools, cranes, and other applications using regenerative Active Infeed technology.
