What this motor is on the line
The 1FK2104-5AF10-1SA0 is a SIMOTICS S-1FK2 HD servo motor from the family built to pair with the SINAMICS S210 drive platform, with a holding brake and an absolute encoder single-turn 22-bit (AS22DQC) on the shaft end. Shaft is D19x40 mm with feather key, degree of protection IP64, and the cable exit is the rotatable M17 plug — so the same motor mounts in either cable-orientation without a special-order variant. Packaging lands at 452.00 x 250.00 x 267.00 mm for one piece; group code R220, product group 9021, product class C — built to order, which cannot be returned against credit once produced. That class tag is the BOM-side cue: lead time is the conversation, not stock.
Ratings and what they mean in the cabinet
Stall torque M0 = 2.4 Nm, with rated power PN = 0.75 kW at nN=3000 rpm on the 380-480 V supply and PN = 0.375 kW at nN=1500 rpm on the 200-240 V supply. Two rated points is the tell that this frame is the high-inertia HD variant of the 1FK2 family — sized for cycles where the load inertia dominates the motor's own rotor inertia, not the fastest point-to-point moves. The holding brake keeps the axis parked when the S210 is in disable, so vertical axes and tool-changer positions hold without a separate brake resistor topology on the drive side. The 22-bit single-turn encoder gives 4,194,304 increments per shaft revolution — the position loop has the resolution to hold tight on a small-format servo press or indexing table, and the S210 reads AS22DQC natively over the OCC interface without a third-party encoder cable. IP64 means the motor body resists splash and dust ingress — the typical machine-build enclosure environment, not a washdown footprint. For food, beverage, or outdoor conveyor duty where IP65 or higher is mandatory, the deployment would need a shroud or a different frame choice.
Compliance and paperwork
RoHS compliance has been in force since 01-07-06 on this product family, and REACH Art. 33 candidate-list disclosure applies per the current Siemens reach information sheet — the EU declaration pack is part of the BOM paperwork, not an extra ask. Export control classification is AL:N / ECCN:N_CNDU — no special export licence gating on cross-border shipment, which keeps the logistics simple for a parallel-import trade or a multi-region build.
Lifecycle status and how to source it
Lifecycle stage is recorded as current and the product status is Active. Product class C, however, flags the manufacturing run as built to order — the lead-time conversation is real, and availability is confirmed at quote rather than pulled off a shelf.
