3.2 Nm stall, 1 kW at 3000 rpm — the loop it closes on a SINAMICS S120
The 1FK2104-6AF00-2SB0 is a SIMOTICS S-1FK2 HD servomotor sized at M0 = 3.2 Nm with PN = 1 kW at nN = 3000 rpm on a 380-480 V DC link, and PN = 0.5 kW at nN = 1500 rpm on a 200-240 V link — meaning the same frame is matched to both the 230 V and the 400-480 V SINAMICS S120 line-up without a re-spec. It belongs to the 1FK2 servomotor family that pairs directly with SINAMICS S120, so the drive commissioning profile, the DRIVE-CLiQ auto-configuration and the safety slot mapping follow the standard SINAMICS topology. Feedback is the single-turn 22-bit absolute encoder AS22DQC (encoder resolution 4 194 304 steps/rev), wired through a DRIVE-CLiQ plug M17 and a power connector size M17 — the DRIVE-CLiQ cable carries both the encoder stream and the electronic nameplate, so on first power-up the drive reads the motor ID without manual parameter entry. A cylindrical shaft D14 x 30 mm and IP64 sealing complete the mechanical side.
Made-to-order class C — what that means for the RFQ
The motor is listed as product class C — products manufactured / produced to order, which cannot be reused or re-utilised or be returned against credit — so each unit ships against a confirmed order and the surplus/return channel does not apply. Packaging quantity is 1 piece in a 452.00 x 250.00 x 267.00 mm shipper; production quantities are quoted per the BOM with the unit price and the build window confirmed at RFQ. RoHS compliance has been in force since 01-07-06 and REACH Art. 33 duty-to-inform applies per the current candidate list.
Encoder and connector decoding for the panel builder
The order code suffix is the engineering shorthand: the trailing -2SB0 pins down the encoder as AS22DQC single-turn 22-bit and the connector as DRIVE-CLiQ M17 plus power M17. A buyer cross-referencing the MPN against the 1FK2 family needs only the frame size (1FK2104, 63 mm stack), the winding (6A, the 1 kW / 3000 rpm version), the encoder option and the connector size to confirm fit — anything else in the dash code is the standard HD configuration. Group code R220 and product group 9021 are the internal Siemens classification lines on the record; they are not selection parameters but they appear on the packing list and the commercial invoice, so they are worth recognising when the goods arrive against the PO.
