400 V 3AC, 0.75 kW, 2000 rpm — sized for the SINAMICS S200 shelf
The Siemens 1FL2306-1AC11-1HB0 is a SIMOTICS S-1FL2 low-inertia servomotor, listed in the 1FL2 family as the matched drive for the SINAMICS S200, with a 400 V 3AC supply, 0.75 kW rated power, 2000 rpm rated speed, 3.58 Nm nominal torque and 3.7 Nm standstill torque at shaft height 65 mm. What that means for fit: the 0.75 kW / 2000 rpm rating is the headline power the SINAMICS S200 axis is sized to deliver, and the 65 mm shaft height is the form factor the 1FL2 frame defines — the motor drops onto the S200 axis mount without adapter plates.
Brake, encoder, IP65 — the mechanical options on this variant
On this build the shaft is supplied with a keyway (tolerance N), fitted with a holding brake, and coupled to a 17-bit absolute encoder wired through an angular connector — the combination a vertical axis needs to hold position on power removal and to retain absolute position across power cycles without a re-homing routine. The motor is rated IP65 with oil seal, which means the housing withstands plant-side splash and dust around the shaft exit — the sealing is at the shaft, not the connector face, so the matching power and encoder leads must be seated to keep the enclosure rating intact.
Made-to-order classification under Group R220 / X0DM
Siemens classifies this part as Group Code R220 under Product Group X0DM, with Product Class C — products manufactured / produced to order, which cannot be reused or re-utilized or be returned against credit. That classification drives the procurement posture: every unit is built against a specific order, and a cancellation cannot be returned for credit.
BOM and service posture
For a BOM freeze this is a clean line item: the S200 drive on one side, the 1FL2 motor on the other, with the encoder cable and power cable as separate line items from the SIMOTICS family. The made-to-order class means lead time is built around factory scheduling rather than shelf stock — quote at the time the BOM is committed, not when the panel is on the floor. Returns and warranty handling on this class follows Siemens' product-class C rule — units built to order are not returnable for credit, so the RMA path is a warranty or fault claim rather than a stock return. Keep the original Siemens packaging through the install and SAT window in case a fault claim needs the nameplate-and-trace evidence.
