What this MPN actually is
The Siemens 1FL2204-4AF01-1HC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family, built to pair with a SINAMICS S200 drive on a 400 V 3AC bus. It is a shaft-height-40 mm motor rated 1 kW mechanical (Pn), with 3.2 Nm standstill torque (M0) and the same 3.2 Nm available as continuous rated torque (Mn) at the rated speed of 3000 rpm — meaning the motor holds full torque right up to base speed rather than tapering early, which is what you want from a point-to-point positioning axis.
Mechanical fit and panel-side integration
The shaft carries a key with N tolerance, no holding brake, and the body ships with an oil seal — that's the right configuration for a clean dry mechanical room where the brake would just add inertia and the unsealed shaft would weep lube past the lip seal. Protection class IP65 with oil seal on a 1 kW servo means the motor tolerates dust and low-pressure water jets typical of a washdown-adjacent line, but it is not rated for full immersion or high-pressure hot cleaning — check the cable gland spec on the hybrid connector for the wet end, not just the housing. Feedback is the 17-bit absolute single-turn encoder (AS17bit) routed through the hybrid connector — pre-wired as one assembly, no separate resolver or battery box to mount, which keeps the cabinet footprint tight and the commissioning checklist short.
Drive pairing and commissioning reality
Siemens states the matching drive as SINAMICS S200 — pick that drive family explicitly in the project file, since the 1FL2 is purpose-matched to S200 and plugging it into a different SINAMICS line can leave encoder scaling and temperature-model parameters unsupported without a firmware add-on.
Lifecycle, compliance, and the BOM line
Lifecycle stage is recorded as current and product status as Active — the part is in normal production, not on a last-time-buy window, and the BOM line can be frozen without a forced re-design. Product class is listed as C (products manufactured / produced to order, which cannot be reused or re-utilized or be returned against credit) — meaning every unit is built against a specific order and a cancelled or surplus unit cannot be returned for credit; size the BOM against confirmed demand, not speculation.
