What the 1FL2306-2AC01-1MB0 actually is
SIMOTICS S-1FL2 servo motor, 1 kW rated power (Pn) on a 400 V 3-phase supply, rated speed 2000 rpm, with a standstill torque M0 of 5 Nm and a rated torque Mn of 4.78 Nm at shaft height 65 mm. Built as part of the 1FL2 family paired specifically with the SINAMICS S200 drive converter — the motor's electrical interface is matched to that servo drive family rather than the older S210 or V90 lines. Configured with an angular connector (AM21bit absolute encoder, single-turn 21-bit resolution), keyed shaft with N tolerance, and no holding brake. IP65 with an oil seal on the shaft exit — so the motor handles washdown and oily environments around the gearbox side, but the brake option was deliberately omitted on this build.
How it sits in the cell — ratings and fit judgement
A 5 Nm standstill with 4.78 Nm continuous at 2000 rpm puts this in the mid-range of the S-1FL2 family — sized for conveyor indexing, small pick-and-place axes, or a secondary rotary table on a robot cell where 1 kW mechanical output closes the cycle budget without overshooting it. The 400 V 3AC supply matches the SINAMICS S200 input class; the AM21bit encoder plugs directly into the drive's encoder port without an external resolver box, which keeps the cell wiring short and the handshake latency predictable. Without a holding brake, this build is intended for applications where the load does not need to be held at rest — a vertical axis under gravity load would need a brake variant instead. Confirm the axis duty before specifying this exact suffix into a vertical-axis BOM line.
Lifecycle and sourcing posture
Product class is C — manufactured/produced to order, non-returnable for credit — which is standard for configured servo motors in this family; orders are built against the configuration rather than pulled from finished-goods stock. Compliance footprint: RoHS-conformant since 01-01-18 and REACH Article 33 disclosure applies — the documentation pack follows the standard Siemens substance-compliance flow. Group code R220 and product group X0DM identify the motor inside Siemens' internal ordering structure — useful cross-references when reconciling the Siemens PO line against the received nameplate.
