1 kW low-inertia axis for SINAMICS S200
The Siemens 1FL2104-4AG11-0HC0 is a SIMOTICS S-1FL2 low-inertia servomotor from the 1FL2 family, specified to pair with the SINAMICS S200 drive on a 200 V 3AC supply rail. Continuous and stall torque both land at 3.2 Nm (M0 = Mn = 3.2 Nm), with the rated point at 1 kW shaft power at 3000 rpm — so the motor can sit at its continuous rating across most of its working speed range without slipping into the short-term S6 region for a packaging or light-conveyor duty. Shaft height 40 mm keeps the motor in the compact class typical of small gantry axes, indexing tables, and pick-and-place gantries where the load inertia sits well below the rotor's own inertia.
Encoder, brake, and shaft options on this code
Feedback on this build is the AS17bit single-turn absolute encoder, which is the resolution matched to the S200 default commissioning profiles and removes the homing pass on every power-up. The integrated holding brake is built in, so the axis holds position on a power-off or E-stop without an external spring-set brake on the gearbox — useful for vertical-axis and tool-change applications where gravity drift after a stop is unacceptable. Output is a plain shaft to tolerance N (no keyway), simplifying the coupling-side mating; the seal is the IP65 oil-seal variant, meaning the motor face is sealed against light oil mist and washdown splash common to machine-tool and food-adjacent enclosures.
Lifecycle, product class, and compliance trail
The Group Code on file is R220 and the Product Group is X0DK — the codes the procurement system uses to route the line through the Siemens configurator without re-keying the full 16-character order string. Packaging ships one piece per carton at 382 × 222 × 240 mm, so a single spare can be shipped economically as a unit carton; multi-piece orders quote the full quantity at RFQ.
