Spec sheet that decides the cabinet layout
The 1FL2103-4AG11-1SC0 is a SIMOTICS S-1FL2 low-inertia servomotor from the 1FL2 family, sized for the SINAMICS S200 drive platform. It is the 30 mm shaft-height frame in that family — small enough to mount on a linear slide or a small indexing table, but still a closed-loop servomotor rather than a stepper. Supply voltage is 200 V three-phase, rated power 0.4 kW at a rated speed of 3000 rpm, with both standstill torque M0 and rated torque Mn at 1.27 Nm. The 1:1 ratio between M0 and Mn tells you the motor is being run essentially at rated torque continuously — there is no thermal headroom to push a heavier load without re-derating, so the mechanical sizing has to honour 1.27 Nm as the working limit, not a peak. Feedback is a 21-bit hybrid encoder and the connector is the hybrid AS21 type — meaning power and feedback share one plug, not two separate cords. Cable management on the cabinet side is correspondingly simpler: one cable per axis back to the S200 drive, not a power lead plus a feedback lead running in parallel. Mechanical build is shaft with key, tolerance N, and an integrated holding brake — the brake holding torque is not separately listed here, so confirm against the S-1FL2 catalogue data before treating it as a vertical-axis safety stop. Protection class is IP65 with oil seal, which closes the gap between motor body and flange against coolant splash and oil mist typical of a machine-tool or packaging environment.
Pairing and system fit
Matching drive is explicitly listed as SINAMICS S200, so the encoder protocol, hybrid connector pinout, and 200 V three-phase bus are already aligned to that platform. Sizing the drive side comes down to the 0.4 kW / 1.27 Nm working point and the dynamic profile of the axis — the S200's auto-tuning will read the encoder type from the nameplate. Export classification shows AL:N / ECCN:N, so this part ships without an export-control gate for the major destinations. That simplifies cross-border spares stocking — the same order code clears customs paperwork in most jurisdictions without an end-use statement.
Lifecycle, compliance, and ordering terms
Lifecycle stage reads as current and product status is recorded as Active — so this is not on a last-time-buy clock and the BOM line can be planned forward against normal replenishment, not against a phase-out window. No additional UL or IEC certification numbers appear in this spec set — confirm the assembly-level listing on the SINAMICS S200 side if the end equipment has to carry a particular panel approval. The product is classed as made-to-order with no return credit — class C, manufactured or produced to order, not reusable and not returnable. For procurement that means cancellation, return, or quantity revision have to be negotiated at order entry; once the unit is built it is a one-way BOM line. Packaging is one piece per shipper at 315 × 182 × 172 mm. Internal Siemens coding is Group Code R220 and Product Group X0DJ, which is how Siemens planning and the S200 drive-side configurator reference the motor — not a buyer-facing spec, but useful when reconciling a Siemens order acknowledgement against the BOM line.
