Where this 1FL2 fits on the SINAMICS S200
The 1FL2203-4AF10-1MC0 sits inside the 1FL2 servomotor family built specifically for the SINAMICS S200 low-voltage drive platform — a compact, high-dynamics pairing for small-format machines where a panel builder needs a matched motor/drive rather than a generic servo. It is a shaft-height-30 mm motor rated at 0.4 kW with a nominal speed of 3000 rpm, and the rated torque equals the stall torque at 1.27 Nm — meaning it holds rated torque down to zero speed without leaving the continuous-duty region.
Ratings a control panel actually keys on
Supply voltage is 400 V three-phase AC, which fixes the upstream branch at the standard 400 V industrial supply; it expects a SINAMICS S200 drive in front of it, not a third-party servo amplifier. Feedback is the 21-bit hybrid encoder (AM21bit) per the variant code, giving absolute position feedback with multi-turn capability — the drive auto-commission expects this encoder type or the resolution figure will not match the standard S200 parameter set. The shaft carries a key with N tolerance and ships with a holding brake; the brake is mandatory for vertical-axis applications because there is no continuous-current holding torque at standstill without it. Protection class is IP54 without an oil seal, so it suits clean, dry cabinet-side or light-dust duty rather than food-and-bev washdown — if the line runs wet, a higher-IP variant from the 1FL2 family is the move, not this one.
Lifecycle, compliance paperwork, and what lands in your cabinet
Lifecycle reads active under the current 1FL2 generation, and the catalogue entry keeps this order code live — no successor or supersession note on the record. RoHS compliance is in force since 01-01-18 and a REACH Article 33 disclosure is published, which is the two pieces of substance-compliance paperwork a pharmaceutical or food-grade integrator typically asks for before sign-off. Export control is AL: N / ECCN: N, so a shipments team does not need an export-licence gate for typical commercial destinations. Siemens classifies the order as product class C — built to order, non-returnable, no reuse credit — which is why the supply posture is quoted against the BOM rather than off-the-shelf shelf stock. The unit ships as one piece per carton at 315.00 x 182.00 x 172.00 mm packaging dimensions, so a single spare fits on a standard shelf footprint without a custom rack.
Sourcing posture for this build-to-order servo
Because the line is built to order with no return credit, the practical path is a quoted RFQ against the confirmed BOM line — availability and current pricing come back at quote time, and the lead-time clock starts from order acknowledgement rather than from a shelf pull.
