What the 1FK2104-5AK10-1MA0 actually is on the shaft
The 1FK2104-5AK10-1MA0 is a Siemens SIMOTICS S-1FK2 HD servomotor from the 1FK2 family sized for the SINAMICS S210 drive platform, rated M0 = 2.4 Nm with a holding brake already integrated and an absolute encoder AM22DQC (22-bit single-turn plus 12-bit multi-turn) on a D19 × 40 mm keyed shaft (cites:,). The OCC interface and rotatable M17 plug on the back are what let a controls integrator land the motor on a S210 line without re-pinning the cable assembly when the cabinet layout rotates the drive. Two power points are published for this frame: 0.75 kW at nN = 3000 rpm on 200-240 V supplies, and 1.07 kW at nN = 6000 rpm on 380-480 V supplies — so the same motor covers both a 230 V-class machine tool axis and a 400 V-class line under the SINAMICS S210 drive (cites:). For a commissioning engineer this is the so-what: the SINAMICS S210 parameter set is what unlocks either operating point; mismatching the drive's line-voltage class with the motor's rated power band is the usual reason the second point never shows up on the nameplate.
Production status and what that means for the BOM
Lifecycle is recorded as active under product class C — built to order, non-returnable, non-reusable — which means each unit ships against a fresh production slot rather than from catalogue stock (cites:,). For a procurement line this shifts the order into a quoted-to-order posture: lead time and price are confirmed at RFQ against the build slot, not pulled from a shelf count. Group Code R220 and Product Group 9021 are the identifiers that should appear on the PO and the Siemens packing slip so the receiving inspection can trace the nameplate back to the build slot (cites:,).
Compliance paperwork the receiving inspector will ask for
Export-control markings AL:N / ECCN:N_CNDU mean this part is not controlled for export, so the customs declaration does not require an export licence entry (cites:).
Where the 1FK2104-5AK10-1MA0 sits in a real machine
The IP64 degree of protection on this frame is a dust-tight, splash-resistant rating — enough for inside an enclosure or a clean machine frame, but not for washdown or outdoor mounting without an additional housing (cites:). Holding brake plus multi-turn absolute encoder means a line-down spare has to match on both the brake winding and the encoder protocol (AM22DQC) before the drive will complete the referencing cycle on first power-up (cites:).
