Where this servo drops in
The Siemens 1FK2104-5AF00-2MA0 sits in the SIMOTICS S-1FK2 HD family and pairs with SINAMICS S210 drives, so the motor lands on the same single-cable OCC bus the drive already speaks. Rated torque M0=2.4 Nm with a continuous shaft output of 0.75 kW at nN=3000 rpm from a 380-480 V link, it covers a mid-range point on the 1FK2 lineup — small enough for indexing tables or small-feed axes, large enough to drive modest conveyor or winding reels.
Encoder, shaft, and the wet-end rating
Feedback is the 22-bit single-turn plus 12-bit multiturn absolute encoder (AM22DQC) over the OCC interface — the drive reads absolute position from power-on without a homing move, which matters where the machine cycles through parked positions on restart. The shaft is the cylindrical D14 x 30 mm profile, and the body is rated IP64; the M17 power/feedback connector is rotatable, so the cable exit can be re-aimed at the panel layout without an extra elbow.
Production status and what gets shipped
Lifecycle reads current — the part is listed as active in production. Unit of sale is one piece per the catalog; the box itself measures roughly 452 x 250 x 267 mm, which is shipping pallet territory rather than bench-side replacement. Product class C flags this as a build-to-order item, so it is not returnable against credit; that has direct implications for spares planning on a line-down replacement.
Compliance pack this part carries
The 1FK2104-5AF00-2MA0 has been RoHS-compliant since 01-07-06 and the REACH Article 33 candidate-list duty-to-inform applies — buyers in the EU expect the Reach Information sheet to arrive with the declaration packet. No ECCN or AL control applies to export classification. Compliance certificates (RoHS/REACH declarations) are what the quality file needs; UL/IEC motor standard markings are not separately confirmed in this catalog row.
