What 1FL2104-2AG11-0MC0 is and where it drops into the panel
1FL2104-2AG11-0MC0 is a Siemens SIMOTICS S-1FL2 synchronous servo in the 1FL2 family, sized for the SINAMICS S200 drive platform — a low-voltage 200 V 3AC brushless servomotor that pairs directly with the S200 without an intermediate coupling stage. Frame and mechanics read off the nameplate at a glance: shaft height 40 mm, plain shaft with tolerance N, oil seal fitted, holding brake included, IP65 protection class — the unit is specified for cabinet-internal mounting where occasional shaft-side contamination can occur but full washdown is not expected.
Headline ratings and what they decide
Continuous rated power is 0.75 kW with a rated speed of 3000 rpm, and standstill torque M0 equals rated torque Mn at 2.4 Nm — meaning the motor holds full torque down to zero speed without a torque fold-back, which is what makes a low-inertia servo useful for point-to-point indexing and short-stroke pick-and-place moves. Supply is 200 V 3AC, the bus voltage the SINAMICS S200 drives from; pairing with a 400 V-class servo drive on the same line would not match this winding, so the BOM position must be specified against the S200 PN/PN set, not the S210 high-voltage line. Feedback is a 21-bit absolute encoder brought out through the AM21bit hybrid connector — the high-resolution single-turn feedback is what gives the S200 closed-loop positioning its repeatability, and the hybrid connector also carries the power leads so a single cable drops to the drive rather than two parallel cordsets.
Commissioning-fit checklist for the S200 line-up
Before the motor lands at the machine, confirm the SINAMICS S200 firmware release notes the 1FL2 motor ID for 0.75 kW / 200 V / 40 mm shaft height — older S200 parameter sets may default to a different frame and need a manual motor-code override at first power-up. The holding brake is wired through the drive's brake output, not from a separate 24 V supply — verify the AM21bit connector pin assignment against the S200 signal diagram because brake polarity reversal is a common commissioning snag on this family. IP65 with oil seal means the shaft exit tolerates light oil mist typical of a machine-tool gearbox bay but is not rated for direct food-grade washdown — if the line deploys the unit into a wet zone, the seal specification has to be re-checked against the washdown chemistry, not assumed from the IP code alone.
Lifecycle, group identifiers, and procurement reality
Group Code R220 and Product Group X0DK are the Siemens internal classifiers used on the packing list and commercial invoice — the quality and documentation pack ties back through these codes, not the order code alone, so any incoming-goods trace into the S200 project should keep both numbers on the receiving record. Commercial class is C — built to order with no return-for-credit pathway — so the order quantity must match the cabinet build plan before release; lead time and current pricing come back against an RFQ rather than from a stocking shelf.
