1 kW, 3.2 Nm, IP65 — what the SIMOTICS S-1FL2 delivers
The Siemens 1FL2104-4BF11-0MC0 is a SIMOTICS S-1FL2 servo motor from the 1FL2 servomotors family, sized for the SINAMICS S200 drive platform. The rated 1 kW output at 3000 rpm with a 3.2 Nm continuous and stall torque means it covers mid-range positioning axes where the load inertia is moderate and the duty cycle is repetitive rather than peak-shock. Supply is 400 V 3AC at the motor terminals — the winding is sized for the SINAMICS S200 converter output, so a mismatched drive module will either under-flux the motor or trip on the converter's motor-data identification. The AM21bit absolute encoder on the non-drive end reports position back over the hybrid connector without a separate resolver cable, simplifying the cabinet-to-machine run.
Shaft height 40 mm, IP65 with holding brake
The 40 mm shaft height and plain shaft with N tolerance are standard for this frame — coupling selection follows the motor-side pilot, not the driven shaft. The integrated holding brake is wired through the same hybrid connector, so a single cable carries power, encoder, and brake signals and the panel-side gland only needs one hole punched. IP65 with oil sealing on a 1 kW servo typically signals washdown-adjacent duty — the shaft seal is the wear item, not the housing. The motor is specified at shaft height 40 mm, which keeps the rotor inertia low enough for the 1 kW class to stay inside the SINAMICS S200 commissioning inertia range without manual gain re-tuning.
Order handling — Group R220, product group X0DK, made-to-order
Group Code R220 and Product Group X0DK are the internal classification Siemens uses for this 1FL2 frame — both come back on the same packing slip, which matters when the MRO storeroom matches receipts against an open purchase order. The product is classed as made-to-order and cannot be returned for credit, so a wrong frame-size call on the BOM becomes scrap rather than a restocking fee. Packing is a single piece in a 382.00 x 222.00 x 240.00 mm carton, which is the factory-shipper footprint — the receiving dock needs to keep the motor upright until commissioning. Export control classifies the part as AL:N / ECCN:N, so no export licence paperwork is required for cross-border shipments.
