The combination — keyed shaft D19x40 mm, absolute encoder single-turn 22-bit AS22DQC, and M17 power connector — defines the motor side of a pre-engineered S120 axis, so the drive-side commissioning macro can load the motor data without manual entry. Two power envelopes sit on the same frame: PN = 1 kW at nN = 3000 rpm on a 380-480 V bus and PN = 0.5 kW at nN = 1500 rpm on a 200-240 V bus. The 480 V envelope covers the European three-phase 400 V industrial rail directly, while the 0.5 kW rating on 200-240 V lets the same motor run on the 230 V class supplies common in North American light-industrial cabinets. Holding brake aside, the IP65 housing lets the motor sit on a machine frame or inside an enclosure near a washdown zone without a separate shroud. ## Commissioning checks that decide fit Power it up and prove it against the encoder ID first — the 22-bit AS22DQC single-turn absolute encoder is wired through the DRIVE-CLiQ M17 plug, and the S120 drive recognizes the motor by electronic nameplate the moment DRIVE-CLiQ links. If the drive does not auto-populate the motor data, the feedback cable pinout or the DRIVE-CLiQ ring is wrong before any parameter page is touched. The brake circuit is a separate harness on the M17 power connector, not part of DRIVE-CLiQ — the brake release voltage and the 24 VDC holding-brake supply must be confirmed against the wiring diagram before the first jog, because the drive enable and the brake release are sequenced independently. Default out of the box the brake is engaged; without 24 V at the brake terminals the shaft stays locked and a move command will fault on the S120 rather than move the load. Mechanical fit is fixed by the shaft: D19x40 mm with feather key. The key way defines the coupling alignment tolerance — an uncoupled or soft-coupled load with the wrong key dimension will index off the shaft shoulder and the absolute encoder will lose its zero reference on the next power cycle. ## Lifecycle, compliance, and ordering context Lifecycle stage is recorded as current and product status as Active, so the 1FK2104-6AF11-1SB0 is in current manufacture as a Group R220 product in Product Group 9021. The product class field flags it as a built-to-order item that is not returnable against credit, which is the standard posture for configured Siemens servomotors — the encoder variant, brake, and connector choice are fixed at order entry. Compliance with the RoHS substance restrictions has been in force since 01-07-06, and REACH Art. 33 duty-to-inform applies against the current candidate list. Packaging ships one piece per carton at 452.00 x 250.00 x 267.00 mm.","metaTitle":"Siemens 1FK2104-6AF11-1SB0 Servo Motor, 1 kW, with Brake","metaDescription":"Siemens 1FK2104-6AF11-1SB0 SIMOTICS S-1FK2 HD servo motor, 1 kW at 3000 rpm, with holding brake and DRIVE-CLiQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"title":"1FK2104-6AF11-1SB0","Group Code":"R220","description":"SIMOTICS S-1FK2 HD servo motor M0=3.2 Nm; PN = 1 kW at nN=3000 rpm (380-480 V); PN = 0.5 kW at nN=1500 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 DRIVE-CLiQ plug M17; power connector size M17;","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 S120","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/9c169a2355b9406b416d8b7742bd7ff0.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/1FK2104-6AF11-1SB0?tree=CatalogTree"},"ai":{"faq":[{"question":"Where can I buy 1FK2104-6AF11-1SB0 and how do I get a price?","answer":"Submit the MPN with the configured options (DRIVE-CLiQ M17, M17 power connector, AS22DQC encoder, holding brake) so the quote matches the build code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK2104-6AF11-1SB0","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/1FK2104-6AF11-1SB0 when reusing this data.
