S-1FK2 HD, 2.4 Nm static — sized for high-dynamic SINAMICS S210 axes
The Siemens 1FK2104-5AK00-2MA0 is a SIMOTICS S-1FK2 HD synchronous servo motor in the 1FK2 family aimed at SINAMICS S210 drives, with a static torque M0 of 2.4 Nm and a rated power PN of 1.07 kW at nN=6000 rpm on a 380-480 V link, dropping to PN=0.75 kW at nN=3000 rpm on 200-240 V — so a single SKU covers both 400 V class and 230 V class cabinets without re-specifying the motor. Position feedback is an absolute encoder AM22DQC with 22-bit single-turn and 12-bit multiturn resolution; the OCC (one-cable connection) interface bundles power and encoder signals through a single M17 rotatable plug, which keeps the cable drag chain clean and removes one cordset from the panel BOM. The shaft is cylindrical D14 x 30 mm and the housing is IP64, so the motor is specified for cabinet-internal or sheltered machine mounting — not for direct food-and-bev washdown or outdoor exposure where IP65/IP67 would be the entry ticket.
Made-to-order class — stock posture and quoting window
Compliance paperwork is on the standard Siemens record: RoHS conformity since 01-07-06 and REACH Art. 33 duty to inform against the current candidate list. Export classification is AL:N / ECCN:N_CNDU, which keeps most regions in scope without an additional licence gate. Orderable as 1 Piece with a single-piece carton footprint of 452 x 250 x 267 mm; spares planning should account for that carton when stocking a hot spare alongside the drive.
Fitment in a SINAMICS S210 axis — what to verify before commissioning
Because the 1FK2 line is built explicitly for the SINAMICS S210 servo drive system, the AM22DQC encoder and the M17 OCC connector pair directly to the S210 — no external encoder adapter, no third-party cable. With M0=2.4 Nm and PN=1.07 kW at 6000 rpm, the motor maps cleanly onto S210 frame sizes rated for the high-dynamic (HD) portion of the family, typically feeding pick-and-place axes, small indexing tables and short-stroke gantries where the dynamic torque margin matters more than the continuous torque number.
