Sizing the 1FL2 against the SINAMICS S200 drive line
The 1FL2204-2BF11-1SC0 is a SIMOTICS S-1FL2 low-inertia servomotor cut for the SINAMICS S200 drive family — a 400 V 3AC bus, 0.75 kW continuous, 3000 rpm rated speed, with a stall torque M0 and rated torque Mn both at 2.4 Nm, so the motor runs flat from standstill to base speed and the drive can hold position without a gearing step. At 40 mm shaft height the frame sits in the small-footprint end of the 1FL2 family — sized for compact cells where a 0.75 kW axis (small indexing tables, light pick-and-place, auger or pump metering drives) is what the cell actually needs, not a larger frame that just adds rotor inertia.
Feedback, brake, and the wiring side
Feedback is the absolute 21-bit single-turn hybrid encoder variant — it gives the SINAMICS S200 the absolute position required for quick commissioning and safe vertical-axis holding without a homing run on every power-up. The holding brake is integral, terminated through the same hybrid connector that carries the power and feedback — one cable dress, no separate brake supply pulled into the panel, which keeps the cell-side wiring tight and the cable loop predictable. Shaft detail matters at install: this build ships with a shaft key and tolerance N, so the coupling choice has to match a keyed input — a slip-fit or clamping hub will not seat cleanly on a keyed shaft without the keyway on the mating part.
Sealing, oil, and where this motor can live
Protection class IP65 with oil seal — the shaft seal is specified for oil exposure, meaning the motor can sit next to a gearbox or hydraulic station without the gearbox oil wicking past the shaft lip and contaminating the encoder bearings in the first year of service. IP65 closes the housing against water jets from any direction, so the motor is fine on a washdown-adjacent line or under a machine housing that gets hosed down — it is not, however, a submersion rating, and it is not the IP67/IP68 you would spec for a motor sitting in a food-zone sump.
Compliance and paperwork for the audit binder
RoHS compliance is declared with effect from 2018-01-01, and the listing carries the REACH Article 33 duty-to-inform flag — meaning the current candidate-list status is shipped with the part documentation rather than left as a buyer-side check. Siemens lists this part as product class C — built to order, no return credit against the original purchase — so an MRO buyer should size spares to actual consumption and not assume a returnable surplus margin.
Lifecycle read and where the BOM line sits
Lifecycle stage is recorded as current on the active Siemens catalogue — no LTB or PCN is showing against this order code, so a fresh BOM line can be designed around 1FL2204-2BF11-1SC0 without a built-in obsolescence hedge. Group code R220 / product group X0DK place this listing on the SIMOTICS 1FL2 line within Siemens's standard servomotor taxonomy — the order code, group, and product group all line up on the same R220 / X0DK slice, which matters when an MRO ticket references the group code instead of the full MPN.
