Form factor and where it drops into the cell
The 1FL2104-4BG11-1HC0: The part is a SIMOTICS S-1FL2 low-inertia servomotor from the Siemens 1FL2 family, sized at shaft height 40 mm with a 200 V 3AC supply and a rated output of 1 kW at 3000 rpm, holding 3.2 Nm from standstill through rated speed — a continuous torque envelope the cell integrator can lean on for short-cycle motion without oversizing the drive. It ships with the hybrid connector, an absolute 17-bit encoder, a keyed shaft with N tolerance, and an integral holding brake; the matched drive is the SINAMICS S200, so the motor-to-drive pairing is locked at the family level and there is no second-source freedom on the commissioning side.
Ratings in plain engineering terms
Pn = 1 kW with Nn = 3000 rpm and M0 = Mn = 3.2 Nm means the motor delivers its full rated torque continuously from zero speed to base speed — useful for packaging and pick-and-place cells that dwell at torque and accelerate without a constant-power speed band at the upper end of the envelope. IP65 with oil-sealed cable entry (the oil-resistant variant matters for machine tools and gear-lube environments), the holding brake takes the axial load when the drive is disabled, and the 17-bit absolute encoder closes the position loop with ~131 000 counts/rev resolution — enough that the controller can land on the index without a homing routine that wastes cycle time.
Sourcing posture and compliance record
Compliance on file: RoHS conformity since 01-01-18, REACH Art. 33 disclosure obligation met, and ECCN / AL classification both N for export-control purposes; packaging is a single-piece shipper at 382 × 222 × 240 mm. The internal identifiers Group Code R220 and Product Group X0DK are the codes the Siemens ordering system uses to route the BOM line; cross them against the S200 drive's order record before committing the motor BOM to make sure the drive firmware slot accepts the 1FL2 motor type.
