1 kW at 3000 rpm — the rating that fixes the slot
The SIMOTICS S-1FL2 motor at the heart of order code 1FL2104-4BF01-0MC0 delivers a rated power of 1 kW at 3000 rpm with both standstill torque M0 and rated torque Mn at 3.2 Nm, meaning the constant-torque region covers the full speed envelope up to nominal without torque foldback — a useful property when the downstream SINAMICS S200 is set up for a machine where the working point sits close to base speed rather than in the field-weakening range. Shaft height 40 mm with a plain shaft (tolerance N) and no holding brake narrows the integrator's choice of gearbox and coupling to those that mount on a 40 mm face and provide their own braking, or accept an external holding arrangement on the driven shaft.
Encoder, sealing, and the SINAMICS S200 pairing
The AM21bit absolute encoder is wired through the hybrid connector, so encoder feedback, power, and the brake pilot (when present on a sibling variant) share a single cable — useful for cabinet builders counting conductors per axis on a multi-axis machine. IP65 with oil seal on a 400 V 3AC servomotor means the shaft seal is rated to keep cutting fluid and light oil mist out of the bearing cavity, which qualifies the motor for machine-tool and packaging-line duty where splash and condensation would defeat a lower-rated servo. Matching drive SINAMICS S200 in the description closes the loop on which drive firmware and motor ID table is correct — pairing outside the S200 family means manual commissioning of the encoder interface and a motor-data download from the Siemens support portal rather than plug-and-play.
Compliance and what the part number carries
RoHS compliance is documented from 01-01-18 onward, and REACH Art. 33 duty-to-inform applies — meaning any substance-of-very-high-concern declaration current at the time of delivery travels with the shipment, not as a separate research exercise. Group Code R220 and Product Group X0DK are the Siemens internal administrative keys used in tender documents and ERP ordering, separate from the order code itself; quoting them in correspondence with Siemens support shortens ticket routing. Product class C — built-to-order with no return-for-credit — is the line a category manager flags on first sight: this is not a stockable shelf item, so the BOM freeze has to happen before the MRP run, not after.
Lifecycle and category sourcing
Lifecycle status is listed as active, so a single-axis retrofit or a new machine build against the SINAMICS S200 platform does not face an end-of-life clock on this motor today. Built-to-order production (product class C) drives the supply posture to quoted-to-order against the BOM: lead time and price-break tier are confirmed at RFQ, not pulled from a price list. Independent distribution can source genuine Siemens product against the order code rather than grey-market substitutes, which is the de-risking lever for a category strategy built around the SINAMICS S200 platform.
