The motor on the BOM line
The Siemens 1FL2304-2AF11-1HB0 is a SIMOTICS S-1FL2 low-inertia servo in the 45 mm shaft-height frame, built to drop onto the SINAMICS S200 drive line that this product family pairs with directly (cites:). Supply is 400 V 3AC with a rated power of 0.4 kW at 3000 rpm and a stall torque of 1.45 Nm against a continuous 1.27 Nm — the stall-to-continuous margin is what lets it absorb accel/decel peaks without saturating the current loop during short indexing moves (cites:). The shaft carries a key with N tolerance and the housing is sealed to IP65 with an oil seal — adequate for a shop-floor axis behind a cabinet door, not for direct washdown. The feedback is an AS17-bit absolute single-turn encoder brought out via an angular connector, and a holding brake is fitted for the vertical-axis cases where a de-energised drop is unacceptable (cites:). Packaged at 382 × 222 × 240 mm per piece, this is a one-up carton rather than a multi-pack — relevant when a tooling builder is kitting a single retrofit axis (cites:).
Where 0.4 kW lands on the axis
A 1.27 Nm continuous / 1.45 Nm peak at 3000 rpm in a 45 mm frame points at auxiliary axes on a machine tool — tool changers, chip conveyors, ATC turrets, small linear-rotary indexers — not at the spindle or a main feed axis. On a five-axis centre, this rating sits comfortably below the main servos and is sized for moves where the cycle time, not the cutting load, sets the throughput (cites:). The SINAMICS S200 pairing is fixed by the product family assignment, so commissioning follows the S200 auto-configuration path rather than a generic third-party drive. PROFINET-side, the encoder resolution and the holding-brake control map into the S200 telegram automatically once the motor is selected in the project — the integrator's job is to verify the direction of rotation and the brake release timing during commissioning rather than to hand-tune the current loop (cites:,).
Compliance and documentation
Export-control classification is AL:N / ECCN:N, so the part is not flagged for an export licence on standard commercial shipments (cites:). The product is classified under Group Code R220 and Product Group X0DM, sold one piece at a time under product class C — built to order against the configured code, not a returnable stock item (cites:,).
Lifecycle and supply posture
Lifecycle stage is recorded as current and product status as Active, which is what the BOM-freeze planning letter needs to confirm before locking a retrofit design into this code (cites:,).
