Plate ratings split cleanly by supply: PN=0.4 kW at nN=3000 rpm on a 380-480 V drive bus, and PN=0.2 kW at nN=1500 rpm on a 200-240 V drive bus — the same winding posted against two mains regimes rather than two motors. ## What M0=1.27 Nm and the holding brake mean on the line M0=1.27 Nm is the standstill torque — the figure that decides whether the axis can hold position under static load at zero speed and how much acceleration headroom the drive has at low rpm before torque saturation. PN=0.4 kW at 3000 rpm sets the continuous mechanical output ceiling when the axis is running, not at stall. The integrated holding brake is sized for parking the axis at zero speed with the drive de-energised — it is a fail-safe holding brake, not a dynamic stopping brake. For emergency-stop or controlled deceleration, the SINAMICS drive handles the dynamic braking through the DC bus, and the holding brake engages only after the rotor has stopped. IP65 means the motor body withstands dust and water-jet cleaning, so the unit is suited to cabinet-less machine frames, food-and-beverage washdown areas, and outdoor skids — but the rating applies to the motor housing with the connectors mated; the sealing surface on the M17 plugs is the wet-end barrier, not the cable jacket. ## Compliance and ordering identity Lifecycle reads as active (current production), and the part is built to order under product class C — built per configuration and not returnable for credit, so the BOM line needs the order code pinned to the exact encoder and connector option at PO. ## Sourcing posture against a capex BOM line Because the part is built to order (product class C), quoting against the project BOM line is the right procurement posture — there is no standing shelf stock to draw down, and the encoder/connector options need to be confirmed at RFQ to protect the commissioning window. Spare-unit planning for startup should ride the same RFQ as the production axis order so the holding-brake and encoder variants match exactly — a mismatched encoder option on a spare will not drop in against an axis commissioned under AS22DQC.","metaTitle":"Siemens 1FK2104-4AF11-0SB0 SIMOTICS S-1FK2 servo, 0.4 kW","metaDescription":"Siemens 1FK2104-4AF11-0SB0 SIMOTICS S-1FK2 HD servo motor, 0.27 Nm / 0.4 kW at 3000 rpm, holding brake, IP65, DRIVE-CLiQ.
