What the module is and where it sits
The Siemens 6SL5120-1UE23-0AD0 is a SINAMICS S220 Single Motor Module in booksize format, sized for a single axis and bolted into the SINAMICS S220 line-up alongside a Line Module that supplies the DC link. It is the inverter slice between the common DC bus and the motor — the Line Module rectifies and regulates, this module chops and switches — which is why every rating on its face is the output side, not the line side.
Ratings that drive the panel sizing
DC-link input spans 495-720 V DC, so the upstream Line Module must hold the bus inside that window under all load and regen conditions or the module will not close its precharge. Firmware floor is FW V5.2 SP3 HF10: commissioning tools, parameter sets, and safety integration are gated to that version, so pairing an older controller or starter commissioning tool with this slice is a known way to lock out parameters at first power-up.
Cabinet envelope and cooling
Booksize D-type chassis with IP20 and internal air cooling only — no cold plate, no liquid loop. The packaging footprint is 365.00 x 565.00 x 110.00 mm, so DIN-rail or backplate layout must clear that envelope plus the bend radius for the DC-link bus bars and the motor cable gland on the underside. Provided the cabinet's forced-air scheme moves enough CFM across the heatsink fins at the rated ambient, the module holds current; in a sealed enclosure, derating kicks in well before the 30 A nameplate figure.
Compliance posture on the BOM
Export-control classification is ECCN 3A999A, so export shipments need the standard ECCN paperwork on file. The internal line codes on the Siemens record are Product Group X0HX and Group Code R220, with the part flagged Product class A (standard stock item, returnable per the standard returns window). These are ordering-line references, not functional specs.
Lifecycle and ordering
The FW V5.2 SP3 HF10 floor is worth flagging to the controls engineer before the cabinet goes to the floor, provided the wider drive lineup is on a compatible firmware baseline.
