Holding torque M0 is 1.27 Nm with a rated output PN of 0.6 kW at nN 6000 rpm from a 380–480 V DC bus, or PN 0.4 kW at nN 3000 rpm from a 200–240 V DC bus, so the same motor covers both the European 400 V class and the North American 240 V class drive cabinets without a mechanical swap. Holding brake is integrated — the brake is wired through the same M17 plug and energised from the S210's brake output, so a vertical axis holds position on power removal without an external brake resistor or contactor. ## Feedback, shaft, and the IP65 cabinet-side story Feedback is a 22-bit single-turn absolute encoder (AS22DQC), which gives 4.19 million counts per revolution — enough resolution that an S210-driven axis can hold sub-arc-minute positioning at the load without an external second encoder on the gearbox output. The shaft is D19 x 40 mm with a feather key, matched to a standard zero-backlash coupling on a planetary or helical gearbox; the IP65 housing sealing is rated for the cabinet-to-machine gap typical of packaging, pick-and-place, and small-format converting lines, where washdown or oil-mist exposure is intermittent rather than continuous. The M17 signal plug is rotatable through roughly 360°, which lets the wireman dress the cable along the cable chain without twisting the connector body — important on S-curve axes where the motor flips end-for-end relative to the harness. ## Lifecycle, compliance, and BOM-fit notes Lifecycle is current on the manufacturer's listing, so the BOM line stays open for new builds — no last-time-buy window applies today, and independent distribution can quote the part against an RFQ at the current Siemens list. RoHS compliance has been declared since 01-07-06 and REACH Article 33 candidate-list information is published for the part, so EU ship-to destinations clear on substance-restriction grounds without a per-shipment derogation. Export control classifies the part as AL:N / ECCN:N_CNDU, which means no export licence is triggered for standard commercial destinations — the paperwork block on a project BOM stays clean. Product class is C — the motor is built to order with a non-returnable, non-reusable configuration, which matters for the procurement clause on a frame agreement: cancellations and quantity adjustments need to land before the production order opens, not after. ## Sourcing posture for the S210 retrofit For an S210 retrofit or line-down spare, the 1FK2104-4AK11-1SA0 is sourced through independent distribution and quoted against an RFQ with the BOM quantity — packaging is 1 piece per shipper at 452.00 x 250.00 x 267.00 mm, so a single-unit spare fits a standard courier carton without a pallet surcharge.","metaTitle":"Siemens 1FK2104-4AK11-1SA0 Servo Motor, 0.6 kW, with Brake","metaDescription":"Siemens SIMOTICS S-1FK2 HD servo motor 0.6 kW at 6000 rpm, holding brake, IP65, AS22DQC 22-bit encoder, for SINAMICS S210.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"title":"1FK2104-4AK11-1SA0","Group Code":"R220","description":"SIMOTICS S-1FK2 HD servo motor M0=1.27 Nm; PN = 0.6 kW at nN=6000 rpm (380-480 V); PN = 0.4 kW at nN=3000 rpm (200-240 V); with holding brake; degree of protection IP65; shaft D19x40 mm with feather key; absolute encoder single-turn 22-bit (encoder AS22DQC); with OCC interface; plug size M17, rotatable;","Product Group":"9021","Product class":"C: products manufactured / produced to order, which cannot be reused or re-utilized or be returned against credit.","Quantity Unit":"1 Piece","Product Family":"1FK2 servomotors for SINAMICS S210","lifecycle_stage":"current","Packaging Quantity":"1","Export Control Regulations":"AL : N / ECCN : N_CNDU","Packaging dimensions (L x W x H)":"452.00 x 250.00 x 267.00 mm","Compliance with the substance restrictions according to RoHS directive":"Since: 01-07-06","REACH Art. 33 Duty to inform according to the current list of candidates":"Reach Information"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/a928d821e946ef1c44abe77a726d5ace.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/1FK2104-4AK11-1SA0?tree=CatalogTree"},"ai":{"faq":[{"question":"What compliance documentation does Siemens provide for 1FK2104-4AK11-1SA0?","answer":"RoHS compliance is declared since 01-07-06 and REACH Article 33 candidate-list information is published on the part record; export control classifies the motor as AL:N / ECCN:N_CNDU, so no licence is triggered for standard commercial destinations."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK2104-4AK11-1SA0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/1FK2104-4AK11-1SA0 when reusing this data.
