1FL2102-4AF10-0MC0 in the SINAMICS S200 axis
The 1FL2102-4AF10-0MC0 is a SIMOTICS S-1FL2 low-voltage servomotor rated 400 V 3AC supply with 100 W rated power (Pn), 3000 rpm rated speed (Nn), and a continuous torque of 0.32 Nm that is identical at standstill (M0) and nominal (Mn), so the motor holds its working torque across the speed envelope without a separate constant-power derate step. It sits in the 1FL2 product family paired with the SINAMICS S200 drive, with a 20 mm shaft height, hybrid AM21bit encoder feedback, plain shaft (tolerance N), an integrated holding brake, and IP54 protection class without an oil seal — a configuration suited to dry, indoor automation cells rather than washdown or food-grade zones.
Ratings that decide fit on the BOM line
100 W at 3000 rpm with 0.32 Nm defines the working point: small-format positioning axes — indexing tables, labellers, small-format pick-and-place, dosing stations, and short-stroke conveyors where the load inertia is low and the cycle demands repeatable stop accuracy rather than sustained torque. The holding brake and AM21bit absolute encoder close the loop on the drive side: the brake holds the axis at rest after a stop (so vertical or inclined axes do not back-drive on power loss), and the 21-bit feedback gives single-turn resolution fine enough for the tight registration moves the S200 typically commands in this power class. IP54 with no oil seal means the motor is built for cabinet interiors and clean industrial atmospheres, not for direct splash, coolant mist, or hygienic-area mounting — confirm the cabinet rating before specifying it for any line with cutting fluid or washdown exposure.
Compliance and change-control posture
The product is classified as made-to-order under product class C — manufactured per order specification and not returnable for credit — so any commitment to a production schedule is a binding build slot, not an off-the-shelf pick; size the order against confirmed demand, not against speculative spares.
Sourcing posture for this build slot
Internal ordering references — group code R220 and product group X0DJ — match across the 1FL2 family line and are the strings to use on a purchase order or RFQ so the build configuration is unambiguous against the configured S200 drive pairing.
