What 1FL2204-2AF01-0MC0 is and where it sits
Siemens SIMOTICS S-1FL2 low-inertia servo in the 1FL2 family, designed as the matched motor for the SINAMICS S200 drive line, Group Code R220 / Product Group X0DK. Rated for 400 V 3AC supply with Pn of 0.75 kW and Nn of 3000 rpm, holding torque and continuous torque both at 2.4 Nm — a low-inertia profile suited to dynamic point-to-point motion rather than long constant-torque duty. Shaft height 40 mm, plain shaft with tolerance N, AM21-bit hybrid encoder interface, no holding brake, IP65 with oil seal — the sealing class is the panel-mount story, so the motor body and cable entry both withstand the typical machine-tool washdown and coolant-mist environment.
Ratings that drive the BOM decision
0.75 kW at 3000 rpm is the continuous rating; 2.4 Nm on both M0 (stall) and Mn (rated) means the motor delivers its full torque envelope right down to zero speed, which is what makes a low-inertia servo the right pick for high-acceleration positioning axes rather than conveyors or pumps. The AM21-bit absolute encoder and hybrid connector lock this motor to the SINAMICS S200 drive — substituting another 1FL2 variant or a third-party servo requires a drive-side firmware slot that accepts the same encoder protocol, not just a footprint match. No holding brake: any axis that needs a fail-safe stop (vertical load, gravity axis) must add an external brake or step up to a braked 1FL2 variant — a plain-shaft, no-brake motor cannot hold position with the drive de-energised. IP65 with oil seal rates the motor for oily machine interiors and casual washdown, not for full submerged or food-grade cleaning — that is the practical ceiling for cabinet-internal mounting near a gearbox or ballscrew.
Lifecycle and the procurement read
Lifecycle stage is current and the official product status is Active, so the motor is still being built to order rather than drawn from a shrinking surplus pool. Product class C — built to order, non-returnable — is the procurement shape here: this is not a shelf SKU you can cancel or restock, every unit is configured against the BOM at the factory and ships against the order. RoHS compliance since 01-01-18 with REACH Art. 33 candidate-list declaration carried through the supplier documentation pack — the declaration trail is in place for EU shipment and audit. Export-control markings AL:N / ECCN:N mean no special-export licence is triggered for typical destinations, which simplifies cross-border RFQ routing against this part. Single-piece packaging at 382 x 222 x 240 mm — the carton footprint is sized for one motor, so multi-axis builds ship as N cartons rather than a consolidated crate.
Sourcing posture for the MRO shelf
Active and built-to-order: the practical move for a storeroom is to standardise on this exact order code for the S200 axis it pairs with, rather than carry a generic equivalent, because the AM21-bit encoder and hybrid connector are the binding choices — a motor that looks similar on paper but speaks a different encoder protocol will not drop in.
