The 380-480 V / 200-240 V pairing means the same frame is shipped into both 230 V-class and 400 V-class cabinets without a winding change, which keeps the spare on the MRO shelf flexible across line voltages. Holding brake is fitted, IP65 housing, cylindrical shaft D19x40 mm, AS22DQC single-turn 22-bit absolute encoder, and an M17 rotatable plug with OCC interface — so commissioning day is plug-in, set the encoder in the S210 project, and run. No laptop archaeology required at startup: the S210 auto-identifies the motor through the OCC interface and the resolver/encoder pairing is pre-validated. ## Ratings that drive the BOM decision The 1.07 kW / 6000 rpm / 2.4 Nm combination places this motor in the compact high-dynamic class for the 1FK2 family — the M0 stall figure is what you derate against for vertical-axis holding, the PN figure is the continuous shaft power available at rated speed, and the dual voltage window (380-480 V vs 200-240 V) is what makes the same order code usable on both 230 V and 400 V line cabinets without a re-spec. The holding brake is sized to hold the rotor at standstill with the rated load, so vertical-axis drops on power loss are held without an external mechanical brake. IP65 sealing covers the dust and low-pressure water-jet duty — fine for cabinet-side mounting and washdown-adjacent zones, but not submersion or high-pressure cleaning. The D19x40 mm cylindrical shaft is the standard keyed mounting interface for this frame, so the coupling and pinion selection is a stock catalogue exercise rather than a custom machining job. ## Compliance, packaging, and what arrives on the dock RoHS compliance since 01-07-06, REACH Article 33 information available on the candidate-list portal, and export-control classification AL:N / ECCN:N_CNDU — i.e. no special export licence is triggered for standard commercial shipments. The packaging dimensions 452.00 x 250.00 x 267.00 mm confirm a single-motor pack; product class is C (made-to-order, non-returnable), which is normal for configured servo motors and worth flagging internally before a unit is pulled off the shelf and returned unused.","metaTitle":"Siemens 1FK2104-5AK11-0SA0 SIMOTICS S-1FK2 servo, 1.07 kW","metaDescription":"Siemens SIMOTICS S-1FK2 HD servo motor, M0=2.4 Nm, PN=1.07 kW at 6000 rpm (380-480 V), with holding brake, IP65, AS22DQC encoder, M17 plug.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"title":"1FK2104-5AK11-0SA0","Group Code":"R220","description":"SIMOTICS S-1FK2 HD servo motor M0=2.4 Nm; PN = 1.07 kW at nN=6000 rpm (380-480 V); PN = 0.75 kW at nN=3000 rpm (200-240 V); with holding brake; degree of protection IP65; cylindrical shaft D19x40mm; 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/80d882a56c3707d6a4f1670be93d3334.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/1FK2104-5AK11-0SA0?tree=CatalogTree"},"ai":{"faq":[{"question":"What does the encoder and plug configuration mean at startup?","answer":"The AS22DQC single-turn 22-bit absolute encoder plus the M17 rotatable plug with OCC interface means the motor is pre-paired to the SINAMICS S210 drive — the S210 auto-detects the motor via the OCC interface on plug-in, so commissioning does not require manual encoder parameter entry.
