What you are mounting on the machine
The Siemens 1FL2203-4AG01-0HC0 is a 1FL2-family low-inertia servomotor built to pair with a SINAMICS S200 drive — a 200 V 3AC machine rated 0.4 kW with 1.27 Nm continuous torque (equal to stall torque M0) at a nominal 3000 rpm, in a 30 mm shaft-height frame with an AS17 hybrid connector and a plain shaft without holding brake. Because this is a low-inertia S-1FL2 unit, it accelerates fast and settles quickly — sized for high-dynamic positioning axes (small indexing tables, feeders, pick-and-place gantries) rather than direct-drive or heavy-inertia conveyor duty where a higher M0 figure would govern the selection.
Sealing, connector, and what sits on the nameplate
Protection class IP65 with oil seal on the shaft — the seal lets the motor sit near gearbox output housings and coolant splash zones where a standard lip seal would wick oil past the bearing, and the AS17 hybrid connector handles power and encoder feedback in one plug so the cabinet-side wiring stays clean. Plain shaft, tolerance N, without holding brake — when the axis needs a fail-safe hold (vertical Z, gravity-loaded sled) you need a brake-option sibling from the same family; the brake-less build is correct for horizontal axes where the drive's own regenerative stop is acceptable. The motor carries Group Code R220 and Product Group X0DJ on the Siemens configurator — those are the internal classification keys, useful when you cross-check a quote sheet or a packing slip against the PO line.
Compliance and what ships with the box
RoHS compliance since 01-01-18 and REACH Art. 33 disclosure obligations satisfied — standard EU substance-restriction posture for current-production Siemens drives components, so this motor can be specified into equipment destined for EEA markets without an extra deviation request. Lifecycle is recorded as Active and the product class is C (built-to-order, non-returnable) — this is a configured servo, not a shelf item, so the supply path runs through RFQ against the BOM rather than off-the-shelf stock.
Sourcing the line-side spare
Because this is a configured build-to-order servo, the procurement posture is quoted-to-order against the RFQ with the build configuration (encoder type, shaft, brake, connector) confirmed against the BOM before release — lead time and unit pricing come back at quote time, not from a published list. Single-piece packaging at 315 x 182 x 172 mm — order multiples for cabinet builds so the configurator consolidates the build rather than producing N independent singles, which compresses total lead time on a multi-axis machine.
