What the 0.4 kW / 1.27 Nm rating means for this axis
The Siemens 1FL2203-4AG00-0HC0 is a SIMOTICS S-1FL2 low-inertia servomotor rated 0.4 kW at 3000 rpm with 1.27 Nm continuous torque — the rated torque equals the stall torque, which tells you the winding is sized for continuous duty across the operating speed range rather than just a peak point. It runs on a 200V 3AC supply and is matched to the SINAMICS S200 drive family; that pairing fixes the converter topology and DC-bus profile on the panel side, so the drive and motor have to land on the same BOM line together.
Mechanical fit, encoder, sealing
Shaft height is 30 mm with a plain shaft (tolerance N) and no holding brake — a vertical-axis application that needs a fail-safe hold has to source the brake variant separately rather than retrofit one in the field. The feedback is an AS17bit hybrid single-cable encoder on a hybrid connector, so the same cable carries power and encoder signals back to the SINAMICS S200 — convenient for cabinet routing but it ties the cable spec to the drive-side mating. Protection class is IP54 without an oil seal, which suits general factory air but rules out direct washdown or oil-mist exposure; a sealed-shaft variant is the answer when the axis sits near a gearbox breath or cutting fluid.
Sourcing posture and compliance
Lifecycle stage is recorded as current, with no official successor cross-reference on file; the part is product class C — built to order, not returnable — so the BOM line should be frozen before release rather than carried as shelf stock. Packaging is single-piece (315 × 182 × 172 mm), and the unit ships as one — no inner multi-pack to break down at receiving.
