Servomotor spec — what fits on the S200
The 1FL2104-4AF00-1MC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family built to pair with a SINAMICS S200 drive — supply voltage 400 V 3AC, rated power 1 kW, rated speed 3000 rpm, with standstill torque M0 and rated torque Mn both at 3.2 Nm, so the motor holds the rated torque all the way down to zero speed without field weakening. A 21-bit hybrid encoder (AM21bit) closes the position loop with the resolution needed for sub-degree indexing on packaging, pick-and-place, and small-format CNC auxiliaries — the resolver-free commutation lets the drive autotune without hall sensors at first commissioning. Shaft height is 40 mm with a keyed shaft, tolerance N, and no holding brake — the holding-brake option is a different order-code variant, so confirm the brake position on the BOM line before specifying this MPN in a vertical-axis application.
Protection class and cabinet fit
IP54 is achieved without an oil seal, so the shaft entry is splash-protected but not pressure-wash rated — the motor is sized for an enclosure or a sheltered machine interior, not for a washdown food-line environment or an outdoor mounting where IP65 or higher is the baseline. The hybrid connector AM21/AM21bit carries power and encoder in one plug, so the cabinet-side cable routing is a single assembly per axis — that simplifies the panel build but ties the encoder protocol to the cable, and field replacement requires the matching Siemens hybrid lead set, not a generic M23.
Lifecycle and sourcing posture
Lifecycle stage is current and the product is listed as Active — it is a build-to-order code in product class C (made to order, non-returnable), so each unit ships against a confirmed PO rather than from shelf stock, and lead time is confirmed at the quote stage, not at the catalog. RoHS compliance is in effect since 01-01-18 and REACH Art. 33 candidate-list information is published — both are required for EU ship-out, and the declarations accompany the shipment on request.
Quoting this code against your BOM
Order code 1FL2104-4AF00-1MC0 is supplied through independent distribution and quoted against the BOM line on RFQ — pricing and current availability are confirmed at quote time, and the same code is matched against the SINAMICS S200 firmware slot on the drive side before the order is committed.
