Sizing the 0.75 kW axis
Siemens builds the 1FL2306-1AC01-1HB0 as a SIMOTICS S-1FL2 servomotor in the 1FL2 family mated to the SINAMICS S200 drive, drawing 400 V 3AC supply and delivering a rated power of 0.75 kW at a nominal speed of 2000 rpm (cites:,). The torque envelope — a stall torque M0 of 3.7 Nm dropping to Mn of 3.58 Nm at nominal speed — sits inside the low-inertia mid-range typical of S-1FL2 sizing, which keeps the acceleration profile usable for short-cycle pick-and-place and conveyor-synchronised cells where closing the cycle budget matters more than peak rpm (cites:).
Feedback, shaft, brake configuration
Feedback is a 17-bit absolute single-turn encoder carried on the AS angular connector, so position is recovered on power-up without a homing sweep — a real gain in cells where the indexing move otherwise eats into the cycle time (cites:). The shaft is supplied with a key and tolerance N, with no holding brake — fine for horizontal conveyors and lightly loaded rotary axes, but a vertical or gravity-loaded axis would need an external brake or a different S-1FL2 variant (cites:).
IP65 oil seal in the cell
IP65 with oil seal on a 65 mm shaft height points at a washdown-tolerant packaging environment — the seal keeps coolant and cutting fluid out of the bearing envelope, so the motor can sit close to the process without a separate enclosure (cites:).
Order class, codes, and compliance trail
Siemens tags this MPN under Group Code R220 and Product Group X0DM, with Product class C — built to order, non-returnable — so a cancelled line item returns against credit rather than as a stock return (cites:,). Compliance carries RoHS conformity since 01-01-18 and the standard REACH Art. 33 candidate-list duty-to-inform statement, with no export-control restrictions (AL:N / ECCN:N) on the shipment itself (cites:,). Lifecycle is active on the Siemens record, with no official successor or second-source cross-reference on file for the MPN (cites:).
