Sizing the motor to the load
The Siemens 1FL2104-4AF10-1HC0 is a SIMOTICS S-1FL2 servo in the 1FL2 family, built to match SINAMICS S200 drives on a 400 V 3AC bus at 1 kW rated power with a 3000 rpm nominal speed — stall and rated torque both sit at 3.2 Nm, so the drive's current loop is sized to a constant-torque profile rather than a high-overload punch. That 1 kW / 3.2 Nm pair lands squarely in the small-payload robotics and pick-and-place envelope; a shaft height of 40 mm with a keyed N-tolerance shaft and an integrated holding brake means the motor drops directly into a gearbox or ball-screw input without an external fail-safe brake stack.
Feedback, sealing, and the panel-side handshake
Encoder is the 17-bit absolute single-turn variant delivered through a hybrid connector — the same hybrid cable carries power and the absolute position feedback, which keeps the panel-side wiring to a single drag-chain lead per axis instead of separate motor-power and signal runs. Protection class IP54 without an oil seal is the rating to plan around: the motor tolerates dust and light splash typical of an enclosed machine frame, but a wet-side food-and-bev or outdoor conveyor application needs the IP-rated variant in the family — IP54 is not a washdown rating.
Lifecycle and the made-to-order note
Product class C flags this as a build-to-order item that cannot be returned against credit — the BOM commit should run with the motor's specific encoder, brake, and connector options locked in, not as a generic stock line, and spares planning should respect the made-to-order lead time. Compliance paper trail covers RoHS conformity since 01-01-18 and REACH Art. 33 duty-to-inform on the candidate list — standard EU environmental documentation rather than any project-specific exemption.
Procurement metadata and shipping footprint
Group code R220 under product group X0DK is the procurement reference pair to drop into the SAP/ERP line so the Siemens ordering system routes the request to the right product tree — these codes, not the MPN alone, drive the factory's build scheduling for a class-C item.
