What this servo is sized for
The 1FL2102-4AG10-1SC0 is a SIMOTICS S-1FL2 low-inertia servomotor from the 1FL2 family, built to pair with the SINAMICS S200 drive and rated at 100 W (Pn) on a 200 V three-phase supply rail. Continuous torque M0 and rated torque Mn both land at 0.32 Nm, so the motor delivers its full holding torque all the way to rated speed — useful when a positioning axis needs to hold position under a static load between moves. Rated speed is 3000 rpm (Nn), which sets the constant-power breakpoint for sizing the mechanical load. Shaft height is 20 mm, the smallest frame in the family — a typical fit for auxiliary axes (conveyor indexers, small feeders, label applicators) where the cycle time is governed by acceleration, not by sustained torque. Feedback is a 21-bit absolute encoder on a hybrid connector, and the motor ships with a holding brake. The brake matters for vertical or overhung loads — without it the axis settles into position only when the drive commands a stop, and any mains loss lets gravity drop the load.
Mechanical interface and protection
Output is a plain shaft with keyway, tolerance N — standard for a keyed coupling or pinion press-fit. Holding brake is integral, so the brake cable is part of the hybrid connector bundle rather than a separate gland. Protection class is IP54 without an oil seal, which keeps the rotating seal out of the BOM but rules out direct splash exposure or coolant mist. For a wet cell or washdown enclosure, the motor needs a cover or a higher-IP variant from the family.
Production status and order code shape
The order code carries lifecycle stage current and the product is listed as active in Siemens records. Group code R220 and product group X0DJ are the administrative handles — they tie back to the Siemens configurator and the SINAMICS S200 accessory catalog, useful when cross-checking the BOM against the factory order form. Product class is C — built to order per the configurator, non-returnable. That rules out the usual 30-day cancellation window common with off-the-shelf parts; the motor is committed the moment the production order opens. Packaging is one piece per box at 315 x 182 x 172 mm.
Compliance posture on file
Export control is AL:N / ECCN:N — no licence trigger for routine cross-border shipment to standard destinations, though the ultimate call sits with the shipper's compliance officer.
