What lands on the backplane when this motor ships
The 1FK2104-5AK10-0SA0 is a SIMOTICS S-1FK2 HD servo motor sized for the SINAMICS S210 drive family — a 2.4 Nm M0 stall with a continuous rating of 1.07 kW at 6000 rpm on a 380-480 V bus, and a lower 0.75 kW point at 3000 rpm on 200-240 V, which is the operating window a SINAMICS S210 line typically sits in. It ships with a holding brake, an absolute encoder single-turn 22-bit (AS22DQC) for commutation and position feedback, IP64 sealing on the body, a cylindrical D19×40 mm shaft, and the M17 rotatable plug that integrates the power and OCC interface — so on a retrofit the cable gland orientation can be set to match the existing cabinet routing without re-drilling.
Sizing the move to a 380-480 V bus versus the 200-240 V shelf
The motor carries two rated points on the nameplate: 1.07 kW at nN = 6000 rpm on 380-480 V, and 0.75 kW at nN = 3000 rpm on 200-240 V — the higher-voltage point is the continuous rating an integrator hits when the SINAMICS S210 sits on a 400 V three-phase rail, and the lower-voltage point covers 230 V retrofit shelves where older controls are being migrated without rewiring the plant. Holding brake and absolute encoder single-turn 22-bit AS22DQC pair with the SINAMICS S210's safety-integrated commissioning — the encoder handles commutation and the brake handles the vertical-axis hold, which is the usual reason a 1FK2 HD is pulled into a packaging or small-format handling line.
Lifecycle status and what it means for a spare-line BOM
The part ships as product class C — produced to order with no reuse or return against credit — so the quote carries a build-to-order lead time rather than a stocked shelf; a maintenance planner who needs a hot spare should treat this as a quoted-to-order line, not a walk-in shelf pick.
Compliance and export posture
RoHS compliance has been in force since 01-07-06 and REACH Art. 33 candidate-list information is published, which is the documentation packet an MRO buyer or independent trader asks for on a Siemens servo-motor BOM line. Export control is AL: N / ECCN: N_CNDU — no special export licence is triggered for standard commercial shipments, which simplifies cross-border quoting for a global machine builder.
