What the order code specifies
The part 1FL2203-4AG11-1MC0 is a SIMOTICS S-1FL2 low-inertia servo in the 1FL2 family, intended to pair with a SINAMICS S200 drive on a 200 V three-phase bus. Rated output is 0.4 kW at a nominal speed of 3000 rpm, with stall and continuous torque both at 1.27 Nm — the matched M0/Mn figures indicate a motor designed to deliver rated torque continuously from standstill without a torque fold-off in the working speed range. Mechanical build is shaft height 30 mm with a keyed shaft (tolerance N), a holding brake for vertical-axis or hold-in-position duty, and an AM21bit hybrid feedback connector for absolute position. Protection class IP65 with an oil seal on the shaft pass-through, which makes the motor suited to cabinet-external mounting where coolant splash and oil mist reach the housing — not full washdown immersion.
Ratings that govern the BOM fit
Supply voltage 200 V 3AC and 0.4 kW continuous place this motor at the low end of the SINAMICS S200 system — small-format handling tables, light indexing axes, and auxiliary feed drives are the working envelope. The 1.27 Nm stall figure is what the holding brake must hold under de-energised conditions; selecting a drive-side brake release threshold above that value is what keeps a vertical axis from drifting on power loss. AM21bit single-cable hybrid connector consolidates power and the absolute encoder on a single pluggable interface, which simplifies the cabinet-to-machine cable run but ties the motor to drives and pre-fabricated cables from the same system — a replacement cable must carry both the power cores and the data pair with the same pinout, not a third-party equivalent.
Lifecycle, compliance, and orderability
RoHS compliance has been in force since 01-01-18, and REACH Art. 33 candidate-list information is supplied with the product per the manufacturer's obligation. Export control markings show AL: N and ECCN: N, which means no special export licence is triggered for standard commercial shipments. The motor ships one per box at outer dimensions 315.00 x 182.00 x 172.00 mm — useful for cabinet-incoming bench space and for the goods-in inspection footprint.
Sourcing posture for the procurement audit
Orderable under 1FL2203-4AG11-1MC0 against an RFQ; the unit is built to order on the Siemens line, so pricing and a confirmed delivery window come back with the quote rather than off a stock shelf. As evidenced by the datasheet description, the matching drive is the SINAMICS S200, and the system-level substitution has to be made at the drive-motor pair level, not the motor alone.
