What 1FL2103-4AG00-1HC0 actually is on the bench
The 1FL2103-4AG00-1HC0 is a SIMOTICS S-1FL2 low-inertia servomotor sized for the 200 V three-phase rail, rated 0.4 kW continuous at a nominal 3000 rpm with 1.27 Nm both at standstill (M0) and rated (Mn) — the equal M0/Mn figure tells the integrator there is no extended constant-power region beyond base speed, so the torque envelope is flat up to Nn. It carries an absolute 17-bit single-turn encoder wired through the hybrid connector on the back of the housing, and the matching drive on the other end of that cable is the SINAMICS S200 — the 1FL2 family is built specifically against that drive's commissioning and safety-Integrated firmware stack. Mechanical fit: 30 mm shaft height with a keyed shaft (tolerance N), no holding brake, and IP54 sealing without an oil seal — that IP figure assumes the hybrid connector is mated and the cable gland side of the installation is sealed, since the body itself does not carry a secondary shaft seal.
Built-to-order commercial code, not a stocked catalog item
Group Code R220 and Product Group X0DJ are the internal commercial keys Siemens uses for order routing and rebate eligibility — they map this motor inside the DRIVE-TECHNOLOGY motion-control cluster and confirm the order code is a current 1FL2 family line. RoHS compliance has been in force since 01-01-18 and the REACH Art. 33 information duty applies; EU ship-to builds will need the current SVHC declaration on file with the goods receipt paperwork.
What this motor actually does on a line
At 0.4 kW and 1.27 Nm this is a small-frame positioning axis — typical deployments are infeed conveyors, labelling heads, small pick-and-place gantries, and packaging-indexing tables where the load inertia is well below ten times the rotor inertia and the cycle rate stays inside the S200 current-loop bandwidth. The absence of a holding brake is the deliberate selection: the application must hold position through spring loading, counter-balance, or a downstream mechanical brake, because powering down the S200 will let the axis coast on its own. If the BOM line called for a brake, this order code is wrong — the brake-equipped variant carries a different suffix in the 1FL2103-4AG00 block. IP54 with no oil seal keeps the motor out of washdown cells and away from cutting-fluid mist; it sits cleanly in a dry panel-side environment or inside an enclosure where the cable entry is the sealing point, not the shaft.
