The shaft is D19 x 40 mm with feather key, which sets the mechanical interface to the gearbox or coupling on the driven axis; the IP65 rating covers the body sealing against coolant splash and cutting mist typical on a tool-making cell. ## Feedback loop and connector stack Feedback is the absolute encoder AM22DQC at 22-bit singleturn plus 12-bit multiturn, returned over DRIVE-CLiQ to the SINAMICS S120 — the resolution and commutation data ride the same cable back to the drive, which is what keeps the position loop deterministic to the cycle and avoids a separate battery box for the absolute track. ## Compliance and export class The motor has been RoHS-compliant since 01-07-06 and is flagged for REACH Art. 33 candidate-list duty to inform; export control is AL:N with ECCN:N_CNDU, so cross-border shipment does not require an export licence under the listed classification. ## Commercial identifiers Commercial identifiers on the record are Group Code R220 and Product Group 9021; the line is classed as a custom-built product manufactured to order (product class C) and ships as a single piece per quantity unit — standard for a configured servo with a specific shaft, brake, and encoder combination.","metaTitle":"Siemens 1FK2104-4AK11-1MB0 SIMOTICS S-1FK2 HD servo, 0.6 kW","metaDescription":"Siemens 1FK2104-4AK11-1MB0 SIMOTICS S-1FK2 HD servo motor for SINAMICS S120, 0.6 kW at 6000 rpm, with holding brake and 22-bit AM22DQC encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"title":"1FK2104-4AK11-1MB0","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 22-bit + 12-bit multiturn (encoder AM22DQC); 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/873081e3e9349b4cec9106cadce382e8.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/1FK2104-4AK11-1MB0?tree=CatalogTree"},"ai":{"faq":[{"question":"What are the rated power and speed points on 1FK2104-4AK11-1MB0?","answer":"PN is 0.6 kW at nN=6000 rpm on a 380-480 V supply, and PN is 0.4 kW at nN=3000 rpm on a 200-240 V supply, with stall torque M0 = 1.27 Nm.
