Servomotor identity and shaft-side spec
The 1FL6090-1AC61-2AG1 is a SIMOTICS S-1FL6 servomotor in the 1FL6 family intended for use with SINAMICS V70 and V90 converters, sized at 90 mm shaft height with an angle plug connector and a plain shaft, no holding brake, and tolerance N. Rated operating voltage is 3AC 400 V with Pn of 2.5 kW at Nn of 2000 rpm, M0 of 15 Nm and MN of 11.9 Nm; feedback is an incremental encoder at 2500 increments per revolution. Sealing to IP65 with the supplied sealing ring is what lets this shaft height 90 frame drop into conveyor or indexing stations where coolant mist and wash residue reach the motor face — verify the mating cable gland keeps the same ingress class at the connector body.
NRND read and what that means for the BOM line
The part is listed as NRND, so it is not a build-out-of-inventory decision — it is a last-time-buy window against the SINAMICS V90 ecosystem, and the 1FL6 family retains an explicit converter pairing rather than a generic cross-line swap. Cross-referees should treat this as a same-family alternate hunt: any drop-in has to hold the 400 V 3AC rating, the 90 mm shaft height, the 2500 incr./rev. incremental encoder resolution, and the no-holding-brake / tolerance N options together — change one, the resolver-and-drive pairing breaks. Compliance: RoHS conformity since 01-01-18, REACH Art. 33 candidate-list information is published by the manufacturer, ECCN AL:N — export paperwork is straightforward but the substance-restriction trail still needs to ride with the decl pack.
Form factor and package identity for the receiving dock
Product class is C — built to order, not returnable for credit, which lines up with the NRND posture: the BOM position has to be locked before the order is placed.
