What the nameplate is telling you
1FL2104-4BG11-1MC0 is a SIMOTICS S-1FL2 low-inertia servomotor sized for a 200 V three-axis drive supply, rated at 1 kW rated power with a 3000 rpm nominal speed and 3.2 Nm standstill/continuous torque — meaning it slots in as the low-inertia axis on a SINAMICS S200 system where point-to-point moves dominate over heavy-continuous extrusion duty. The 40 mm shaft height positions it as the small-frame member of the 1FL2 family. Mechanical package reads for panel-level integration: hybrid connector AM21bit, keyed shaft with N tolerance, holding brake, and IP65 sealing with oil-resisting seal — a build suited to factory automation cells where occasional lubricant mist reaches the housing, not to food-grade washdown or outdoor cabinets.
Fit to SINAMICS S200 and commissioning posture
The description block pairs this motor explicitly with the SINAMICS S200 drive — the drive performs the auto-identification on first power-up, recognises the 21-bit AM21bit encoder, and resolves the holding-brake control timing from the motor's electronic rating plate. Substitute the motor only within the same 1FL2 family; controller parameter sets for neighbouring families do not migrate cleanly across encoder and brake-wiring variants. Holding brake and IP65-with-oil sealing are factory-fit options — the order code suffix encodes both, so a swap on the line cannot drop a non-brake motor into a brake-expecting application without a parameter change in the drive's safety configuration.
