The motor delivers a 0.6 kW rated output at 6000 rpm on a 380-480 V bus (M0 = 1.27 Nm), with a 0.4 kW / 3000 rpm point on the 200-240 V bus, so a single SKU covers both 230 V and 400 V class line-ups without a re-spec. Shaft and feedback package are fixed: D19x40 mm shaft with feather key, absolute encoder AM22DQC at 22-bit single-turn plus 12-bit multiturn resolution — the keying, stack length, and feedback type must match the existing axis when this SKU is dropped into a replacement BOM. IP65 protection on the housing suits shop-floor deployment with splash and light dust exposure, but the rating does not extend to washdown — for hygienic or food-grade lines, the next step up in the family's sealing options is the operating constraint. Siemens lists the product as Active with a current lifecycle stage, so production is ongoing and the order code is the long-term buy, not a last-time-buy placeholder. ## Ratings that drive fit on the panel and in the cabinet The 1.27 Nm stall torque and 0.6 kW continuous rating sit at the compact end of the 1FK2 family — this is the high-dynamic servo frame for short-cycle motion, not a heavy-duty spindle drive, and the duty cycle has to be checked against the application's RMS torque at peak. At 6000 rpm on the 380-480 V bus the motor keeps a flat torque plateau typical of SINAMICS S120 matched servos, which is what gives the dynamic response the 1FK2 HD series is specced for in pick-and-place, packaging, and small-format converting axes. The AM22DQC encoder returns absolute position across power cycles, so the controller does not need a homing routine after every E-stop or mains dip — a concrete advantage on machines with frequent mode changes. Packaging ships one piece per carton at 452.00 x 250.00 x 267.00 mm — sized for standard parcel freight rather than palletized container loads, which keeps the inbound logistics simple for a service spare or single-axis retrofit. ## Compliance posture for cross-region builds RoHS compliance has been in force since 01-07-06 and REACH Article 33 disclosure is maintained per the current candidate list, so EU and most APAC builds accept this part without a separate substance declaration file. Export control is rated AL:N / ECCN:N_CNDU, which means no special export licence is required for typical cross-border industrial shipments — a routine paperwork note for the logistics planner. Siemens classifies the order as product class C — manufactured to order, non-returnable for credit — which sets the procurement expectation that lot sizes and cancellations follow the factory's build cycle rather than shelf inventory. ## Procurement and order administration Group Code R220 and Product Group 9021 are the internal Siemens ordering slots, useful when raising the line on a Siemens portal or matching it against an existing frame agreement.","metaTitle":"Siemens 1FK2104-4AK01-1MB0 Servo Motor, 1.27 Nm, 0.6 kW","metaDescription":"Siemens 1FK2104-4AK01-1MB0 SIMOTICS S-1FK2 HD servo motor, 1.27 Nm, 0.6 kW at 6000 rpm, IP65, DRIVE-CLiQ.
