What's bolted to the back of a SINAMICS S200?
The Siemens 1FL2306-1AC11-0MB0 is a SIMOTICS S-1FL2 low-inertia servo motor from the 1FL2 family, factory-matched to the SINAMICS S200 drive line. It runs on a 400 V 3AC supply rail and delivers Pn = 0.75 kW at Nn = 2000 rpm, with a stall torque M0 of 3.7 Nm and a rated torque Mn of 3.58 Nm — the small gap between M0 and Mn is the headline cue that this is a low-inertia winding optimised for high dynamic response rather than continuous stall duty.
Mechanical and feedback package on this build
The 65 mm shaft height places it in the compact S-1FL2 frame range; the plain shaft with tolerance N and the AM21-bit absolute single-turn encoder close the mechanical and feedback interface, while the integrated holding brake handles the vertical-axis / E-stop static load case. The cable exit is the angular connector variant — buyers should match the cable set (power + signal) to the AM21-bit encoder pinout, not to a generic 1FL2 lead, because the angular connector geometry and the encoder pin map together as a single mating assembly. IP65 with oil seal means the shaft seal holds against light oil mist and washdown — adequate for packaging and food-adjacent lines, but it is not an IP67 submerged-duty rating, so the motor housing should still be mounted away from direct jet spray zones.
Production class and what it does to a lot purchase
Siemens classifies this order code under Product class C — produced to order, not re-usable or returnable for credit — so a unit pulled from a liquidation pallet cannot simply be returned against stock; it has to be sold on its own merit. Lifecycle stage is listed as current and product status as Active, which means the factory is still taking orders for the build, but the make-to-order class means every unit is built against a confirmed PO rather than pulled from a finished-goods buffer.
Compliance paperwork to expect with the shipment
RoHS compliance has been declared since 01-01-18, and REACH Art. 33 candidate-list information is supplied with the product — both are part of the standard EU conformity paperwork for a current-production S-1FL2 unit. Export control is listed as AL: N / ECCN: N, which means the part is not on a controlled-export list and can move under standard commercial export paperwork.
