Ratings and what they size for
The Siemens 1FL2102-2AG11-1MC0 is a SIMOTICS S-1FL2 low-inertia servo rated for a 200V 3AC supply with a continuous output of 50 W (Pn), 0.16 Nm stall torque (M0) and 0.16 Nm rated torque (Mn) at 3000 rpm (Nn) — the 1:1 stall-to-rated ratio means the motor is sized to deliver its rated torque continuously without a thermal derating margin, so the load profile should be reviewed against Pn rather than peak torque. The shaft height is 20 mm and the encoder is a 21-bit absolute multi-turn (AM21bit) on a hybrid connector, paired with a holding brake and an IP65 sealing package with oil seal — a configuration that targets compact point-to-point axes where the brake holds the load at standstill and the absolute encoder eliminates the home-return on power-up.
Drive pairing and panel fit
The motor carries the SIMOTICS S-1FL2 family designation for direct pairing with the SINAMICS S200 drive line — the hybrid connector is matched to the S200 power-and-signal cable set, so a substitution outside the 1FL2 family will typically require a different cable harness and a different drive firmware slot, not just a parameter change. Shaft key with Tolerance N fit, oil-sealed IP65 housing, and packaging dimensions of 315 x 182 x 172 mm define the panel cut and the cabinet volume — the 20 mm shaft height frames the part as a low-power auxiliary axis (conveyor diverters, small indexing tables, label applicators, dosing pumps) rather than a main spindle.
