The 1UF0 build of this 132 kW SINAMICS G120X is the unfiltered Ethernet build of the frame: PROFINET and EtherNet/IP onboard for the plant network, DC link terminals for the du/dt filter on long motor runs, and the power stage shipped without radio-interference suppression so the site EMC standard decides the filtering.

Why pair an unfiltered power stage with full Ethernet?

Because the two choices are independent — and plants with central EMC infrastructure still want the diagnostics. The suppression lives in the site-standard hardware; the drive contributes 256 A LO (132 kW continuous) against the 338 A maximum, 110 kW in HO duty, and reports load, energy and fault data over the dual-protocol port to whichever automation layer owns the plant.

What does the site need to plan around an unfiltered build?

The EMC category is no longer set by the drive. With the filter external, the installation defines the emission class — which is exactly the flexibility the U-suffix exists for, and exactly why the C2- and C3-filtered siblings share the frame for sites that prefer the integrated route. The 305 x 709 x 360 mm FSF housing and the 110%/60 s, 100%/240 s overload envelope are common across all 132 kW order numbers.
