Servo motor sized for tight-axis work
The 1FL2203-4AG00-0SC0 is a SIMOTICS S-1FL2 low-inertia servo in the 1FL2 family, built to pair with the SINAMICS S200 drive. Rated output is 0.4 kW at 200 V 3AC with a rated speed of 3000 rpm, and both standstill torque M0 and rated torque Mn land at 1.27 Nm — meaning the motor delivers full holding torque right down to zero speed without field weakening, which keeps the loop deterministic on positioning moves. It is a 30 mm shaft-height frame with a plain shaft to tolerance N, no holding brake, and an IP54 protection class without an oil seal. The 21-bit single-turn hybrid encoder (AS21) sits on the rear — high enough resolution that following error stays inside a few microns on a well-tuned axis, and the feedback link to the S200 drive runs over the matching hybrid connector.
Mounting, environment, and what the IP rating actually permits
IP54 with no oil seal means the body resists dust ingress and splashing water from any direction, but it is not a washdown-rated enclosure. Mount it inside a control cabinet or a covered machine housing where coolant, oil mist, and direct jet spray cannot reach the shaft seal area — typical of a machine-tool auxiliary axis or a small parts handler rather than a wet-process line. Because there is no holding brake, the axis needs a mechanical brake elsewhere (gravity load, vertical slide) or the application must tolerate the motor spinning down freely on power removal. The plain shaft to tolerance N assumes a keyed or clamp-style coupling — verify the coupling's radial load rating against the application's peak torque before commissioning.
Catalog identifiers and compliance paperwork
The part carries Group Code R220 under Product Group X0DJ, ships as one piece per package, and is classified as a product manufactured/produced to order that cannot be reused or returned against credit — so a mis-spec on the BOM stays as a sunk cost, not a credit-memo path.
Lifecycle and how to source it
No official successor or second-source cross-reference is listed for this order code in the family — the 1FL2 line is the active generation for the SINAMICS S200 platform, and the AS21 encoder/hybrid-connector pinout is specific enough that a drop-in from another family would require a re-spin of the cable set and the drive parameter set. Because the part is built to order (class C), volume is quoted against the BOM line and lead time confirmed at RFQ — not pulled from a stocked shelf. Packaging dimensions of 315 x 182 x 172 mm on a single-piece shipper are typical for a small-frame servo, and no price or stock figure is asserted here.
