What the 1FL2104 is sized to do
Siemens 1FL2104-2AF01-0MC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family built to pair with the SINAMICS S200 drive line, with a 400 V 3AC supply, 0.75 kW rated power, 3000 rpm rated speed and a 2.4 Nm continuous (Mn) and 2.4 Nm stall (M0) torque — so the matching inverter is sized for a continuous shaft load around 750 W, not a peak-duty profile. Mechanical package is a 40 mm shaft height with a plain shaft (tolerance N), no holding brake, IP65 protection class with oil seal, and a single-cable hybrid AM21bit connector — meaning feedback and power share one hybrid cable and the encoder is the 21-bit absolute multiturn type the SINAMICS S200 expects out of the box.
RoHS compliance has been in force since 01-01-18 and the part falls under REACH Art. 33 duty-to-inform, so the declaration pack is straightforward; no ECCN / AL export flag is set, which keeps cross-border shipping routine for industrial-automation destinations.
Where this 1FL2 fits in a panel
The S-1FL2 / SINAMICS S200 pairing is the compact servo stack for small-format machines — typically short-cycle handling, indexing tables, labelling and small-format packaging where the 0.75 kW / 3000 rpm envelope covers the load and the 2.4 Nm continuous torque is the figure that governs sizing, not the headline rating. IP65 with oil seal at the shaft entry plus the hybrid AM21bit connector means the motor body tolerates light washdown and oily shop-floor atmospheres that would defeat a standard IP54 servo; the shaft height of 40 mm and plain-shaft, no-holding-brake build suits vertical-mount and gravity-loaded axes where an external brake on the gearbox is preferred.
Cataloguing and packaging on record
Siemens lists the part under Group Code R220 and Product Group X0DK, supplied as one piece per quantity unit with carton dimensions of 382 × 222 × 240 mm — useful when the MRO storeroom is forecasting shelf space for a mixed pallet that includes this frame size.
