Sizing the axis off the nameplate
The 1FL2104-2BF11-1HC0 is a SIMOTICS S-1FL2 low-inertia servo, ordered against a 400 V 3AC bus and delivering 0.75 kW at a 3000 rpm rated speed, with stall torque and continuous torque both rated at 2.4 Nm on a 40 mm shaft height. Holding brake and shaft key are fitted, encoder is the 17-bit absolute single-turn (AS), and protection is IP65 with oil seal — meaning it absorbs the panel-side coolant splash common to wet machine tools without a secondary bellows. It belongs to the 1FL2 family, which is the SIMOTICS line matched to the SINAMICS S200 drive platform — the motor and drive pair share the hybrid connector and parameter set, so the integration is a one-cable-commissioned axis rather than a retro-fit to an older S120 or V90 line.
Production reality and how to source it
Siemens lists the lifecycle stage as current, so the motor is still being built to order rather than discontinued — no last-time-buy window applies. Group code R220 and product group X0DK are the procurement routing keys inside the Siemens ordering system; an RFQ against the correct code lands in the buildable backlog rather than the surplus channel. The product class is the built-to-order C category: configured and produced per order, non-returnable, non-reusable against credit. Order qty 1 piece, packaged 382.00 x 222.00 x 240.00 mm — that footprint is a single-axis carton, not a bulk pack, so spares ship as the configured unit rather than a generic SKU.
Compliance posture for the BOM file
Export control is AL:N / ECCN:N, so cross-border shipment to standard destinations carries no licensing trip.
