Sizing envelope for an S-1FL2 low-inertia axis
The 1FL2103-2AF10-0HC0 is a SIMOTICS S-1FL2 low-inertia servomotor from the Siemens 1FL2 family, built to pair with the SINAMICS S200 drive family. At a 400 V 3AC supply it delivers a rated power of 0.2 kW at 3000 rpm with a continuous torque of 0.64 Nm — standstill and rated torque are both listed at 0.64 Nm, so the motor has no constant-power fold-down over its base speed range and is sized for a continuous-duty axis rather than a field-weakening application. Shaft height 30 mm and IP54 protection class without an oil seal suit a clean, dry cabinet-mounted axis — pump, indexing table, small linear stage — not a wet or gearbox-through-shaft duty. Feedback is the absolute single-turn encoder (AS, 17-bit) and the cable exit is the hybrid AS connector, which combines power and signal in one plug — this matches the SINAMICS S200 drive-side connector and keeps the cabinet wiring to one motor cable rather than a separate encoder line. A holding brake is fitted, so the motor can hold a vertical axis at rest with the drive disabled; the shaft is the plain, tolerance N variant with no keyway, intended for a clamp-style coupling.
Active lifecycle and order-class posture
Lifecycle stage for the 1FL2103-2AF10-0HC0 is listed as current, meaning the part is in active Siemens production with no phase-out notice attached. The product is classified as Product class C — manufactured or produced to order, which cannot be reused, re-utilised, or returned against credit — so an order placed against the wrong motor variant typically cannot be taken back, and the BOM line should be confirmed against the S200 drive assignment and the brake/encoder option codes before release.
Packaging and cross-reference codes
The motor ships one per carton at 315 × 182 × 172 mm — a single-axis pack size, not a multi-pack — so inbound handling and shelf footprint match a low-inertia 30 mm-frame servomotor rather than a mid-frame drive. Siemens-internal ordering references are Group Code R220 and Product Group X0DJ; both are administrative codes used on the order acknowledgement and packing slip rather than functional ratings.
