What this motor is, and why the SINAMICS pairing matters
The 1FL2304-4AF01-0HB0 is a SIMOTICS S-1FL2 low-inertia servomotor rated 0.75 kW with a standstill torque M0 of 3.02 Nm and rated torque Mn of 2.39 Nm at Nn = 3000 rpm, sized for the SINAMICS S200 drive family. Shaft height 45 mm keeps it inside the compact S-1FL2 envelope, so panel layout and cable routings follow the same mechanical pattern as the rest of the 1FL2 line. Supply voltage is 400 V 3AC, and the encoder is the 17-bit absolute single-turn AS17 (angular connector) — that combination is the parameter set the SINAMICS S200 expects when auto-configuring the drive, so a mismatched feedback variant will not drop straight into the same axis slot without manual commissioning.
Brake, sealing, and shaft detail — the so-what for installation
The build is plain shaft (tolerance N) without a holding brake, and the protection class is IP65 with oil seal. IP65 with oil seal is the right call for general factory atmospheres and gearbox-adjacent mounting — the seal keeps oil mist from creeping into the bearing cavity — but it is not a washdown rating, so food-and-bev lines or direct hose-down zones need a different enclosure strategy. Because the holding brake is omitted, any vertical axis application has to handle the static load through the mechanics or add a third-party brake — the motor itself will not hold position on power loss.
Build-to-order class and what that means for the BOM
Siemens classifies this motor as product class C: produced to order, non-returnable, non-reusable. Lifecycle stage is current (active). Quoted to order against the BOM — Siemens does not stock this configuration in finished-goods inventory, so a confirmed order is the path to a shipped unit rather than a shelf pick. Packaging is one piece per shipper at 432 × 222 × 240 mm, and Group Code R220 / Product Group X0DM govern the internal Siemens logistics routing — useful when reconciling a packing slip against the purchase order.
Compliance posture
RoHS compliance has been in force since 01-01-18, and REACH Art. 33 information is supplied per the current candidate list. Export control markings are AL: N / ECCN: N, which simplifies cross-border paperwork compared to controlled parts.
