Which drive family is this motor wound for?
The 1FL2104-4AF11-1SC0 is a SIMOTICS S-1FL2 low-inertia servo from the 1FL2 family, wound for 400 V 3AC and explicitly matched to the SINAMICS S200 drive platform. Rated 1 kW continuous, 3000 rpm rated speed, with 3.2 Nm standstill and 3.2 Nm rated torque, so it lands in the small-frame S200 sizing band where the drive's current loop and the motor's torque constant are pre-paired at the factory. Built as a 40 mm shaft-height machine with a keyed shaft (tolerance N), integrated holding brake, 21-bit hybrid encoder connector, and IP65 protection with an oil seal — meaning the housing tolerates coolant splash and oily plant air common to machining cells, while the brake holds the axis at standstill when the drive's enable drops.
Build-to-order class and packaging
Siemens classifies this order code under product class C — manufactured or produced to order, not returnable for credit — so a cancelled line item cannot be restocked into the seller's shelf. The quantity unit is one piece per orderable line, and the factory packaging envelope is 382.00 x 222.00 x 240.00 mm, sized for a single motor with its connector kit. For panel builders this means the motor drops into the standard S200 cabinet layout with no extra adapter plate, but the build-to-order class means quantity breaks and cancellation terms need to be confirmed before the BOM freezes — not a part to overspec into a one-off prototype run.
Lifecycle and compliance posture
No official L* successor or cross-reference appears in the ledger, so any second-source decision has to be engineered against another frame size or another vendor family, not against a Siemens-published replacement. Group code R220 and product group X0DK are the Siemens-internal classification keys used for pricing and product-line reporting.
