1 kW, 5 Nm, 2000 rpm — sized for the SINAMICS S200 loop
The 1FL2306-2AC01-1SB0 is a SIMOTICS S-1FL2 servo motor from the 1FL2 family built specifically to pair with the SINAMICS S200 drive family, so the electrical loop, encoder interface, and tuning profile are matched out of the box rather than bolted on after the fact. Rated 1 kW continuous (Pn=1 kW) at a 400 V 3AC supply with a nominal speed of 2000 rpm, a standstill torque M0 of 5 Nm and a rated torque Mn of 4.78 Nm — the 0.22 Nm gap between M0 and Mn is the working headroom the drive uses to accelerate inertial loads without leaving the constant-torque region. Encoder is the 21-bit version with the angular connector AS21, which carries the absolute position feedback the S200 needs for commutation and the safe-motion functions; specifying a different encoder variant on the same frame changes the order-code suffix, not the mechanical fit.
Shaft height 65 mm, IP65 with oil seal — what the mechanical envelope actually means
Shaft height is 65 mm with a keyed shaft to tolerance N and no holding brake, which is the typical choice for horizontal axes where gravity does not pull the load on a power loss; if the application is a vertical axis, the same frame ships with a brake in the -2 brake-suffix variant — confirm before committing to a BOM line. Protection class is IP65 with an oil seal on the shaft pass-through, so the motor body and shaft seal withstand jetting water and oil mist typical of machine-tool and conveyor enclosures; the seal is the consumable item in this rating, not the housing, and its service life follows the duty cycle of any gearbox it drives.
Build-to-order class, RoHS and REACH posture
Product class C — manufactured to order, not reusable and not returnable for credit — which is standard for Siemens servo configurations and frames the sourcing posture: each unit is built against the order, not pulled from a generic shelf, so lead time is driven by the factory schedule, not distributor stock. RoHS compliance is confirmed since 01-01-18 and REACH Art. 33 information is published, and the part is not export-controlled (AL:N / ECCN:N,) — so cross-border shipments into standard industrial markets do not require an export licence on the part itself.
