SIMOTICS 1FL2 servo, sized for a 400 V three-axis pack
The Siemens 1FL2204-2AF11-1MC0 is a SIMOTICS S-1FL2 low-inertia servo from the 1FL2 family, paired explicitly with the SINAMICS S200 drive platform and rated for a 400 V three-phase supply at 0.75 kW continuous with a 3000 rpm nominal speed and 2.4 Nm standstill/continuous torque. On the mechanical side the motor is built on a 40 mm shaft-height frame, ships with an AM21-bit hybrid encoder, a keyed shaft to ISO tolerance N, a holding brake for vertical-axis and rapid-stop retention, and an IP65 enclosure with oil seal so the assembly survives coolant splash and panel-side washdown common on machine tools and packaging lines.
What 0.75 kW at 3000 rpm actually means for sizing
The 2.4 Nm continuous figure at 3000 rpm is the load point the SINAMICS S200 has to be parameterised against — it sets the S200's current-loop scaling and the thermal model the drive uses to flag overload, so undersizing the drive or picking a non-S200 amplifier breaks the one-cable commissioning profile the family is designed around. The holding brake is integrated at the factory rather than retrofitted on the panel, which matters for Z-axis and indexing-drum duty where the brake has to hold without a separate 24 V brake chopper wiring harness — the motor arrives brake-ready, not brake-pending.
Lifecycle posture and compliance paper trail
Lifecycle is recorded as current and active, so the order is a forward-production buy rather than a last-time-buy or NRND play; the line falls under group code R220 / product group X0DK and the part class is built-to-order with no return-for-credit path, which is the standard Siemens posture for configured servomotors. Compliance is documented for the European market: RoHS conformity is declared since 01-01-18, REACH Art. 33 candidate-list information is published, and the part is not export-controlled (AL:N / ECCN:N), which simplifies cross-border shipment and import paperwork. Logistically the motor ships one per carton in a 382 × 222 × 240 mm pack, so receiving needs a bench or roller table rather than a small-parts bin — useful to flag for stores if the line is being rebuilt and several units are arriving together.
