What this motor is, and where it drops in
The 1FK2104-4AF01-1MA0 is a SIMOTICS S-1FK2 HD servo motor sized for the SINAMICS S210 drive family — a low-inertia permanent-magnet servo rated at M0=1.27 Nm, with a 0.4 kW continuous at nN=3000 rpm on a 380-480 V bus and a derated 0.2 kW at nN=1500 rpm on 200-240 V, so the same frame covers both 230 V-class and 400 V-class line voltages without a hardware change beyond the converter. Feedback is an AM22DQC absolute encoder at 22-bit single-turn plus 12-bit multi-turn (roughly 4 million counts/rev plus 4096 turns of absolute position retention), wired through the OCC interface on a rotatable M17 plug — the position survives a power-cycle and the panel can be entered without a homing sequence at every startup.
Mechanical and environmental envelope
The shaft is D19x40 mm with a feather key, suiting a standard servo-class coupling or pulley without a custom bore adapter, and the housing is sealed to IP65 — the body tolerates directed water jets and dust ingress, which is the case a panel builder needs covered when the cabinet sits near a washdown cell or an outdoor skid. Mechanical integration is a standard SIMOTICS S-1FK2 HD frame with a rotatable M17 connector at the back, so the cable entry can be re-aimed after the motor is bolted to the gearbox or mounting flange without unmounting the assembly.
Lifecycle status and compliance posture
Material-compliance documentation on file: RoHS compliance since 01-07-06 and REACH Art. 33 candidate-list disclosure is published, which clears the part for new equipment going into the EU market without an extra dossier from the cabinet builder. Export-control classification on the record is AL:N / ECCN:N_CNDU — no special licence is triggered for routine cross-border shipment of the carton-level unit.
Sourcing posture for the BOM line
Order quantities are quoted against the BOM through independent industrial distribution with the build-to-order lead confirmed at RFQ; the unit ships singly (Quantity Unit 1 Piece, Packaging Quantity 1) in a 452.00 x 250.00 x 267.00 mm carton, which is what a panel builder should expect when a single replacement is being added to a machine under construction.
