1FL2103-2AF01-0SC0 — SIMOTICS S-1FL2, 0.2 kW / 0.64 Nm, paired to SINAMICS S200
The Siemens 1FL2103-2AF01-0SC0 is a member of the 1FL2 servomotor family engineered as the matched low-inertia axis for the SINAMICS S200 drive platform, ordered under Group Code R220 and Product Group X0DJ. Its nameplate draws a 400 V 3AC supply at a rated mechanical output of 0.2 kW with a continuous stall and rated torque of 0.64 Nm at a base speed of 3000 rpm — the size of machine it actually drives is the small-format indexing axis, the lab automation carriage, or the precision feed on a packaging or electronics line, not a heavy conveyor or press.
Mechanical and electrical envelope — 30 mm shaft height, IP65 oil-seal body
Shaft height 30 mm with a plain shaft (tolerance N) and no holding brake — so the motor holds position only while the drive loop is closed; a vertical axis that must remain stationary with power removed needs an external holding brake, not this build. Protection class IP65 with oil seal means the body tolerates light coolant splash and oil mist typical of a machine tool enclosure, but it is not rated for submerged washdown — for food-and-beverage or outdoor exposure, look higher up the 1FL2 range rather than relying on this rating. Connection is via a hybrid connector on the motor housing, matched to the SINAMICS S200 power-and-signal cable family — the encoder and power share a single moulded lead, so field replacement is the whole cable assembly, not a pin-by-pin repair.
Feedback resolution and drive pairing
The integrated AS21bit encoder delivers single-turn resolution that suits precision point-to-point positioning at the 0.2 kW class — adequate for clean registration moves and small-format part handling, not for high-end multi-axis CNC contouring where a 24-bit or absolute multi-turn feedback would normally be specified. Because the motor is sold against the SINAMICS S200 drive as a matched pair, the commissioning engineer configures it from the drive's motor database rather than entering nameplate parameters by hand — the encoder type, pole count, and thermal model are pre-loaded, which removes the most common commissioning mistakes for this class.
Lifecycle, build class, and compliance pack
It is built under product class C: made-to-order, not reusable, and not returnable for credit — so a panel builder or MRO planner specifying a spare needs to order against the actual requirement, not pad the BOM and reconcile later.
Receiving, packaging, and order code
Order unit is 1 piece with packaging dimensions of 315 × 182 × 172 mm — small enough that receiving inspection and shelf storage are routine, not a dedicated crate, and a panel builder can hold one or two as commissioning spares without a special cabinet. The full Siemens order code 1FL2103-2AF01-0SC0 carries the family prefix, frame size, winding, feedback option, connector type, shaft style, brake option, and protection class in a single string — cross-reference against the SINAMICS S200 drive's motor list before releasing the PO, because an unverified substitution inside the same family will not drop into the drive's auto-configuration correctly.
