5 kW at 2000 rpm — 1FL6 shaft performance
The Siemens 1FL6094-1AC61-2LG1 is a SIMOTICS S-1FL6 servomotor from the family sized for the SINAMICS V70 and SINAMICS V90 converter platforms, and its electrical envelope is the line's mid-frame: 3-phase 400 V supply, rated power Pn=5 kW at rated speed Nn=2000 rpm, with stall torque M0=30 Nm and rated torque MN=23.9 Nm. Stall torque at 30 Nm against rated torque near 23.9 Nm means roughly an 80% torque margin between zero speed and full speed — enough headroom for the acceleration transients typical of indexing tables and short-cycle conveyors driving the same V90 bus.
Encoder and mechanical fit-out
Feedback is a 20-bit absolute encoder (12-bit multi-turn) read straight off the angle plug, so the controller knows shaft position from power-up — no homing routine, no dropouts after a controlled stop. The shaft is a plain, unkeyed configuration, tolerance N, no holding brake fitted. Shaft height 90 mm sets the frame. IP65 with the sealing ring fitted on the shaft pass-through; the standard rotor is matched to the V70/V90 drive for one-cable commissioning on that ecosystem. The mounting is the standard SIMOTICS S-1FL6 flange footprint for the 90 mm frame.
Lifecycle signal — NRND on the family
For line-down recovery on an installed base, the practical route is independent distribution quoting against an RFQ — sealed, traceable stock with the manufacturer pedigree is sourced in this channel for NRND Siemens servo SKUs, and lead time and pricing are confirmed at quote.
Compliance and shipping posture
Class C product manufactured to order, single-piece quantity unit, shipper footprint 495 mm x 365 mm x 340 mm, packaging quantity 1 piece. Export control classification reads AL:N / ECCN:N, so it crosses most borders without a per-shipment export licence. Substance compliance: RoHS conformity since 01-01-18, with a REACH Art. 33 duty-to-inform disclosure on file — relevant for EU installations where the candidate-list status has to be carried in the technical file supplied with the machinery.
