A 1 kW low-voltage servo for a SINAMICS S200 axis
The Siemens 1FL2104-4AG11-1HC0 is a SIMOTICS S-1FL2 low-inertia servo, 1 kW rated power on a 3-phase 200 V supply with a 3.2 Nm continuous torque at 3000 rpm, shaft height 40 mm, holding brake, multi-turn 17-bit encoder over the hybrid connector, IP65 with oil seal, and shaft-key balance to tolerance N (cite:). It belongs to the 1FL2 servomotor family intended as the matched motor for the SINAMICS S200 drive platform — same frame language, same connector family, designed for that pairing rather than as a standalone retrofit (cite:).
Shaft-height and frame for panel-side sizing
At shaft height 40 mm with a hybrid connector outlet and keyed shaft, the motor drops into the standard 1FL2 frame footprint used across the SINAMICS S200 range — cable bend radius and connector orientation follow that family, not a generic metric-frame pattern (cite:). The IP65 rating with oil seal on the shaft end means the motor body and shaft seal hold up to light coolant splash and oil mist typical on a small CNC, a packaging line, or a feeder axis — the holding brake sits behind that same seal envelope so retention is unchanged (cite:).
Production status, ordering class, and paperwork
The catalog entry tags it under Product class C — built-to-order, non-returnable, non-reusable, which matters when you spec a spare because each motor has to be committed against a build slot rather than drawn from shelf returns (cite:). RoHS compliance has been in place since 01-01-18 and REACH Article 33 information is supplied with the shipment, so the EU paperwork ships with the motor — that covers most European panel builders without an extra document request (cite:,).
Catalog codes MRO will see on the box
The Siemens ordering system files this motor under Group Code R220 and Product Group X0DK — those are the codes that show up on the packing list and invoice, not the marketing description (cite:,). Shipping configuration is single-piece at 382 x 222 x 240 mm, so if you order spares for two cells they ship as two cartons, not consolidated — plan the receiving dock for that footprint per motor (cite:,).
