Compact servo for SINAMICS S120 — what this motor delivers
The Siemens 1FK2204-6AF10-1MB0 is a SIMOTICS S-1FK2 CT servo motor in the 1FK2 family built for the SINAMICS S120 drive platform — a 3.2 Nm (M0) unit rated 1 kW at 3000 rpm on a 380–480 V bus and 0.5 kW at 1500 rpm on a 200–240 V bus, sized for the compact end of the SINAMICS-driven machine axis where a holding brake is required for vertical or inertial loads. It carries an absolute encoder AM22DQC (22-bit single-turn + 12-bit multi-turn) over a DRIVE-CLiQ M17 plug and a power connector M17, so the motor talks natively to a SINAMICS S120 control cabinet without an external SMC/SME module — the DRIVE-CLiQ link carries encoder data, motor nameplate, and thermal model straight into the drive on first power-up.
Mechanical and environmental envelope
The shaft is D19 × 40 mm with a feather key and the housing is rated IP64 — adequate for factory-floor cabinet and machine-internal mounting where the motor sits inside the equipment envelope rather than in a washdown or outdoor position; the holding brake is integral, so the part number already covers vertical-axis safe-stop and E-stop retention without an add-on brake module. Product class C — built-to-order, not returnable for credit — which is the standard Siemens posture for configured servo motors in the 1FK2 line: the encoder option, brake, connector, and shaft detail lock the build at order entry, and the same configuration is then held in the project BOM rather than pulled from distributor shelf stock.
Compliance documentation carried with the part
Lifecycle stage is recorded as current on the Siemens Group Code R220 / Product Group 9021 line; the export-control classification is AL:N / ECCN:N_CNDU, so the part ships without an export licence gate for most commercial destinations — only a final ECCN check at the order desk for non-standard destination countries is normally needed.
Sourcing posture — built-to-order, BOM-locked
Product class C drives the supply path: this 1FK2204-6AF10-1MB0 is not pulled from generic shelf stock — it is configured and built against the BOM, so a project-build order is placed against the specific encoder (AM22DQC), brake, connector (M17), and shaft detail (D19 × 40 mm with feather key), and lead time plus volume pricing are confirmed at RFQ against the quantity and the destination.
