What slots into the cabinet
The 6SL5120-1UE23-0SD0 is a SINAMICS S220 single motor module in the Single Motor Modules in booksize format family — a 15 kW, 30 A output stage designed to feed one servo motor from a common DC bus inside a multi-axis drive lineup. Headline I/O: 495-720 V DC input off the shared bus and 0-480 V three-phase output at 30 A, which sets the 15 kW nameplate. Booksize D-type footprint, IP20 enclosure, internal-air cooling only — so it lands in a closed cabinet with the matching SINAMICS S220 line filter and reactor, not next to the motor. Siemens lists the part as current production, group code R220, product group X0HX, pack quantity one piece, with export classification AL:N / ECCN:3A999A.
Field wiring checklist before power-on
The booksize D-type frame and IP20 rating are intentional — the module depends on a sealed cabinet for its enclosure rating, with the front-face heatsink pulling internal air only. Airflow clearance from the cabinet layout must be respected before you close the door, since the same D-type body is shared across the 15 kW and adjacent power ratings in this product family. Packaging dimensions 365.00 x 565.00 x 60.00 mm align the module to a standard booksize slot, so it docks with adjacent line modules and motor modules in the same SINAMICS S220 lineup without re-engineering the mounting cutout. Group code R220 ties it to a single Siemens price/discount bracket for stock-keeping.
Compliance posture for the BOM reviewer
Export control sits at ECCN:3A999A, which is the standard catch-all for industrial drives — a routine customs classification, not a licence trigger for most destinations, but still part of the export paperwork bundle.
Sourcing posture for the line-down spare
FW gating sits at SINAMICS V5.2 SP3 HF10 or higher, so a field replacement needs the active firmware baseline loaded on the host controller before commissioning or the module will reject handshake.
