Nameplate ratings and what 100 W at 3000 rpm buys you
Siemens 1FL2102-4AF10-1MC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family sized for the SINAMICS S200 drive line, rated 400 V 3AC supply, Pn=100 W, Nn=3000 rpm, M0=0.32 Nm and Mn=0.32 Nm, with a 20 mm shaft height and an integrated holding brake. The 0.32 Nm continuous and stall figure is the working envelope — at 3000 rpm that maps to roughly 100 W mechanical, which puts the motor in the small-format pick-and-place and tabletop indexer class rather than conveyor or spindle duty. Mechanical build is shaft-key with tolerance N, AM21bit hybrid feedback connector, and IP54 protection without an oil seal — the through-shaft is not sealed for gear-oil environments, so mounting outside the gearbox housing is the natural fit.
Drive pairing and feedback resolution
1FL2 servomotors are listed as the matching motor family for SINAMICS S200 drives, so the drive-side parameter set, encoder database, and one-button auto-tuning path are pre-loaded for this combination — match the inertia first on the load side and the auto-tuner takes care of the loop. AM21bit absolute encoder feedback closes the position loop with 21-bit single-turn resolution, giving sub-arc-minute positioning on short moves; the current-loop bandwidth on this small-frame class is what lets the velocity loop run fast without singing.
Lifecycle status and order class
The product is classified as made-to-order — class C, manufactured per the configuration at order entry and not returnable against credit — so the BOM line should be frozen before release and lead time confirmed against the build slot. Group Code R220 and Product Group X0DJ are the internal ordering headers that the Siemens configurator uses to route this code into the SIMOTICS S-1FL2 build pipeline.
Packaging and handling at receipt
Supplied one piece per carton at 315 x 182 x 172 mm packaging dimensions — small-frame servo packaging sized for the motor body, hybrid connector pigtail, and the holding-brake lead, with no separate shipper required.
