What the headline numbers mean on the bench
The 1FL2203-2AF00-1MC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 30 mm shaft-height frame, sized at 0.2 kW with a rated speed of 3000 rpm and a continuous/peak torque of 0.64 Nm on both M0 and Mn — meaning the motor delivers its rated torque flat from standstill to base speed with no pull-down at low rpm, which is exactly the profile a small CNC auxiliary axis or pick-and-place joint needs for clean following error. It runs on a 400 V 3AC supply, is wound for the SINAMICS S200 drive family, and is shipped without a holding brake and without an oil seal — the unbraked, no-seal configuration suits horizontal axes where gravity load is not a parked-state concern, and keeps the rotor stack short for the lowest possible inertia in the loop. Feedback is the 21-bit AM21 single-turn absolute encoder on a hybrid connector: 21-bit resolution is roughly 2 million counts per revolution, which lands comfortably above the 17–18-bit threshold where cyclic sampling noise starts to dominate the position loop on small servos — the loop stays deterministic to the cycle rather than quantisation-limited.
Mechanical fit and cabinet-side integration
The shaft is a keyed, Tolerance N output with a 30 mm flange, which gives a standard face-mount footprint that drops into the usual machine-builder bracket pattern for small servo axes. Protection class is IP54 without an oil seal — the motor is sealed against splash and dust ingress typical of a cabinet-adjacent or clean-shop-floor machine, but is not rated for washdown or food-grade duty.
Lifecycle, compliance and sourcing posture
For the buyer's traceability line, the part carries Group Code R220 and Product Group X0DJ — these are the identifiers that have to match the Siemens PO so the drive's electronic nameplate pairs cleanly with the motor's serialised data at first commissioning.
