What this motor is and where it bolts in
The 1FK2104-4AF10-0SA0 is a SIMOTICS S-1FK2 HD servo motor from the 1FK2 family built for the SINAMICS S210 drive line, with a 0.4 kW nameplate rating at a nominal 3000 rpm on a 380–480 V bus and a derated 0.2 kW at 1500 rpm on 200–240 V. It carries an integrated holding brake, an IP64-protected housing, a cylindrical D19×40 mm shaft, a single-turn 22-bit absolute encoder (AS22DQC), and a rotatable M17 connector with the OCC interface — so the same frame drops into S210 cabinets without re-pinning the cabinet side.
Torque, speed envelope, and brake duty
The standstill torque M0 is 1.27 Nm with PN = 0.4 kW at nN = 3000 rpm on the 380–480 V supply and PN = 0.2 kW at nN = 1500 rpm on 200–240 V — pick the 400 V class supply when the application demands full continuous power; the 230 V class is the lower-rail derate for plants wired single-phase-heavy. The holding brake is part of the motor assembly, so the safety stop is local to the shaft — when specifying the S210 drive, confirm the brake is released through the drive's enable path and not held by an external contactor, otherwise the brake's holding torque gets duplicated against the drive's ramp-down and the shaft overruns.
Encoder, connector, and panel-side fit
The single-turn 22-bit AS22DQC absolute encoder resolves 4,194,304 steps per turn — fine enough for direct-driven positioning without an external load-side encoder on most packaging and small-format motion axes. The M17 plug is rotatable, so the cable exit can be clocked after the motor is mounted to the machine — useful when the cabinet layout forces a non-standard cordset orientation and you would rather not stock a left-hand vs right-hand motor variant. IP64 means dust-tight and resistant to splashed water, but not rated for pressure washdown — keep this frame out of food-and-bev zones that demand IP65 or higher; it belongs on the dry side of the machine or inside an enclosure.
Compliance and supply classification
The motor has been RoHS-compliant since 01-07-06, with REACH Art. 33 candidate-list information supplied on demand, and carries no export-control flag under AL:N / ECCN:N_CNDU — meaning standard cross-border shipment documentation applies rather than a dual-use export license.
Production status and how to source it
It ships as a single-piece carton with packaging dimensions 452.00 × 250.00 × 267.00 mm; since the part class is built-to-order with no return credit, the order should be quoted against the full BOM quantity up front rather than staged through sample-and-release.
