What this servo delivers on the load side
The Siemens 1FL2104-4AG00-0HC0 is a SIMOTICS S-1FL2 synchronous servo in the 1FL2 family, mechanically and electrically matched to the SINAMICS S200 drive — paired the way Siemens ships them, no up-front sizing surprise. Continuous-rated at Pn=1 kW with Nn=3000 rpm, and a stall/continuous torque figure of M0=Mn=3.2 Nm in the 40 mm shaft-height frame — meaning the motor holds rated torque down to a near-standstill, so cyclic point-to-point moves on a small gantry or feeder indexer land inside one continuous-duty envelope without an extra gearbox. Three-phase 200 V AC supply matches the SINAMICS S200 200 V line directly; the 17-bit single-turn absolute encoder resolves position for the S200 commissioning tool, and the hybrid connector carries power and feedback in one cable harness.
Mechanical interface and what it rules out
Plain shaft with tolerance N (no keyway, no feather key) and no holding brake — so the load must back up the holding function by a secondary mechanical brake or by a counterweight in the gravity axis if the axis can drift on a power loss. Protection class IP54 without an oil seal — the IP rating is on the body/face seal, not the shaft bore; if the machine sees cutting fluid or oil mist at the shaft, plan a sealed through-bore on the gearbox or a separate shaft seal on the driven side rather than expecting this motor to keep it out. Shaft-height 40 mm and the 1FL2 footprint position it inside the S200 small-frame envelope — mechanical drawings on the S200 documentation set define the flange tolerance and mating connector orientation; the S200 drive side is the controlled variable, not the motor side.
Compliance, packaging, and what changes the order line
Product class is C — built to order, not returnable for credit — so the order code and lead time are locked in at RFQ; the exact cable length, connector orientation, and shaft variant should be checked against the BOM before the PO is released, because a re-spec after order means a new build. Single-piece pack in a 382 × 222 × 240 mm carton — useful for the MRO desk planning storage space and the receiving dock's slot allocation; nothing multi-pack to break down.
