400 V 3AC low-inertia axis for SINAMICS S200
The 1FL2304-2AF01-1MB0 is a SIMOTICS S-1FL2 low-inertia servomotor built to run off a 400 V 3AC supply, sized at Pn = 0.4 kW with a rated speed of Nn = 3000 rpm and a standstill torque of M0 = 1.45 Nm against a rated torque of Mn = 1.27 Nm, so it sits in the small-frame end of the SINAMICS S200 axis family. Encoder is the AM21bit absolute single-turn unit on an angled connector — no battery, no multi-turn memory — which is the standard S200 axis feedback choice and means commissioning only needs the SINAMICS one-button auto-tune, not a homing sequence at every power-up. Mechanical build is shaft height 45 mm with a keyed shaft to tolerance N and no holding brake, so the load has to be held by the drivetrain itself when power is removed — for vertical axes that lack a counterbalance or external brake, spec a different frame option.
IP65 sealing and the oil-seal detail
Protection class on this code is IP65 with oil seal, which seals the shaft exit against light coolant and cutting-oil splash common on small CNC, packaging and pick-and-place lines — the seal limits ingress but does not survive submerged or high-pressure washdown, so for food-and-bev lines spec the next IP rating up. It is matched to the SINAMICS S200 drive family, so the motor cable, encoder cable and brake connector are the S200 cable set — using legacy SINAMICS V70/V90 cable assemblies on an S200 is the most common fit error on rebuilds.
Sourcing posture for the BOM line
Because the code is built-to-order, availability is quoted against the BOM quantity and confirmed at RFQ time rather than pulled from shelf stock — ordering against a planned production run avoids the surcharges that come with expedite requests on a made-to-order part. A single unit ships in a 382 × 222 × 240 mm carton with a packaging quantity of 1, which matters for a shop floor taking one spare against a single S200 axis rebuild rather than a panel builder running a multi-axis cell.
