SH40 frame, 1 kW continuous — what the rating buys
The 1FL2204-4AF11-1MC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family, built to run on the SINAMICS S200 drive side — supply voltage 400 V 3AC, rated power Pn 1 kW, rated speed Nn 3000 rpm, with standstill torque M0 and rated torque Mn both stated at 3.2 Nm. The M0 = Mn profile means the motor holds its rated torque down to zero speed, which is what you want from a point-to-point axis that dwells under load between moves. At SH40 shaft height with a 1 kW continuous rating, this frame slots into the same S200 sizing window as the other SH40 1FL2 motors — a packaging or pick-and-place axis running roughly a 3 Nm continuous load is the natural fit, and anything that asks for more than 3.2 Nm continuous at 3000 rpm should move up to the next shaft height rather than be overdriven from this one.
Encoder, brake, sealing — mechanical decisions baked into the -1MC0 suffix
The -1MC0 suffix fixes the mechanical build: hybrid cable connector (one cable for power + encoder + brake), 21-bit single-turn absolute encoder (AM21-bit), shaft with key and N tolerance, holding brake, and IP65 protection class with oil seal. Match the mating hybrid connector on the SINAMICS S200 side and the brake lead is on the same cable — no separate brake connector to land in the panel. The oil seal at the IP65 rating is the part that lets this motor sit next to a gearbox or ball-screw without gearbox oil wicking past the shaft into the encoder, which is the usual failure mode on SH40 frames in a machine tool or gantry cabinet.
Active, made-to-order — what that means for the BOM
Siemens lists the 1FL2204-4AF11-1MC0 as active in the current lifecycle stage, in product group X0DK and group code R220. Compliance package covers RoHS compliance since 01-01-18 and REACH Art. 33 duty-to-inform on the current candidate list. Export control markings are AL:N / ECCN:N, so the part ships without a special-export licence gate in most jurisdictions. Packaging is one piece per carton at 382 x 222 x 240 mm. Production-class C rules out holding inventory of finished goods, so availability is quoted against the RFQ at the configured configuration rather than pulled from a shelf — the BOM line is locked once the order is released, and any change to encoder, brake or connector option means a new build slot rather than a field swap.
