Rated output is PN = 0.4 kW at nN = 3000 rpm on a 380–480 V supply, with a derated PN = 0.2 kW at nN = 1500 rpm on 200–240 V; standstill torque M0 = 1.27 Nm — the constant that sets the low-speed torque ceiling for sizing the axis. It is the low-to-mid inertia HD (High Dynamic) frame the family is built around, so it fits the typical S210 packaging, pick-and-place, and indexing axis where the holding brake has to hold vertical loads at standstill. ## Mechanical envelope, encoder, and connector The shaft is D19 × 40 mm with a feather key — the keyed shaft is the one that drives the load, so the mating coupling or pulley has to be matched to a 19 mm bore and a keyway. Holding brake, IP64 degree of protection, and an M17 rotatable power/signal plug with OCC interface give the field-side view: brake for vertical-axis lock, IP64 for typical plant air (not washdown), and a rotatable connector so the cable exit can be set on install without rotating the whole motor. The 22-bit single-turn absolute encoder (AS22DQC) gives 4,194,304 counts per revolution — fine resolution for indexing, and single-turn means multi-turn position retention requires a separate gear or battery-free absolute tracking scheme on the drive side.","metaTitle":"Siemens 1FK2104-4AF10-1SA0 SIMOTICS S-1FK2 HD servo, 0.4 kW","metaDescription":"Siemens 1FK2104-4AF10-1SA0 SIMOTICS S-1FK2 HD servo motor with holding brake, 0.4 kW at 3000 rpm, IP64, single-turn 22-bit AS22DQC encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"title":"1FK2104-4AF10-1SA0","Group Code":"R220","description":"SIMOTICS S-1FK2 HD servo motor M0=1.27 Nm; PN = 0.4 kW at nN=3000 rpm (380-480 V); PN = 0.2 kW at nN=1500 rpm (200-240 V); with holding brake; degree of protection IP64; 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/5f67fade5a01be7307cdb76393bb6fdf.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/1FK2104-4AF10-1SA0?tree=CatalogTree"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK2104-4AF10-1SA0","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/1FK2104-4AF10-1SA0 when reusing this data.
