Headline ratings and what they drive
The 1FL2204-4BF11-1MC0 is a SIMOTICS S-1FL2 low-inertia servomotor sized for 400 V 3AC operation, rated 1 kW (Pn) at a nominal speed of 3000 rpm, with both standstill and rated torque at 3.2 Nm — meaning the continuous and starting torque are equal here, so the motor delivers full torque across the working speed band without a derating step from M0 down to Mn. Holding brake and IP65 with oil-seal, 40 mm shaft height, AM21bit hybrid connector — the package is built for cabinet-adjacent machines where shaft sealing against coolant ingress matters more than a food-grade stainless finish. Family pairing is fixed: the matching drive is SINAMICS S200, so any replacement on a line-down must keep the drive family in the loop — a 1FL2 wired to a different servo drive platform won't see the encoder channel the same way.
Lifecycle and ordering reality
Lifecycle is recorded as current/active, so the BOM line stays open; product class is C (made-to-order, non-returnable), which is the Siemens convention for configured servo motors — quote against the exact MPN, don't swap a generic.
Sourcing posture for the BOM
Made-to-order Siemens servo motors ship on project lead times, not from shelf stock — supply against the BOM is quoted per RFQ, with quantity, delivery window, and traceability confirmed at quote time. Group code R220 and product group X0DK are the internal ordering handles to put on the PO and the decl pack; shipping pack is one piece per carton at 382 × 222 × 240 mm.
