400 V 3AC, 0.75 kW low-inertia servo on the S200 drive bus
The 1FL2304-4AF01-0SB0: It pairs with the SINAMICS S200 drive family as the matched motor side of that system — the encoder resolution, winding, and mechanical interface are designed against the S200 drive, so substitution onto a different drive platform normally needs a re-commissioned motor and may need a firmware-side sensor change. The encoder interface AS21bit is the resolver-replacement digital commutation feedback for that platform.
Lifecycle, compliance, and what that C-class rating does to your RFQ
Compliance posture is European: RoHS conformity since 2018-01-01 and REACH Article 33 duty-to-inform carried against the current candidate list — sufficient for CE-marked machinery but buyers shipping into UL-listed or UKCA-bound panels should still confirm the panel-level approval rather than assuming the motor carries every regional mark. Internal catalog fields place it under group code R220 and product group X0DM — useful for Siemens ordering-system lookups and for matching a cross-reference request against the same product group, but not a functional rating a buyer acts on.
Sizing the 0.75 kW / 3.02 Nm frame into the axis
The M0 3.02 Nm stall figure is roughly 25% above the Mn 2.39 Nm continuous rating, so the motor carries transient overload (acceleration torque, peak cutting load) headroom on the same frame without needing a one-frame-up step. Shaft height 45 mm with an IP65 oil seal and a plain shaft defines the mechanical envelope — it expects a backlash-free coupling or a direct-to-gearbox mount, not a belt-and-pulley stack, and the oil seal adds friction at low speed that matters for hold-position loops. Order-unit is a single piece in packaging of 432 x 222 x 240 mm, which is the shippable carton for the configured motor — no inner multi-pack to split for a one-off replacement. Single-piece ship cartons follow the part anywhere a service spare goes.
