What NRND means for a 7 kW SIMOTICS S-1FL6
Siemens 1FL6096-1AC61-2LG1 sits in the SIMOTICS S-1FL6 low-inertia family built to run on the SINAMICS V70 and SINAMICS V90 servo drives — a 3AC 400 V, 7 kW continuous (Pn) shaft rated for 2000 rpm nominal with 40 Nm standstill torque (M0) and 33.4 Nm rated torque (MN), in a 90 mm shaft height, plain-shaft, no-holding-brake configuration behind an angle connector and a 20-bit (12-bit multi-turn) absolute encoder. Lifecycle reads NRND — not recommended for new designs — which is a procurement signal, not a build-out one: existing fleets stay supported but the catalog is being wound down, and replacements are being phased in. For a line-down spare this still buys time; for a new machine design the right move is to confirm the active successor on the SINAMICS V90 motor side before committing to a new BOM line.
7 kW, 40 Nm standstill, IP65 — what those numbers decide
Pn=7 kW at Nn=2000 rpm with M0=40 Nm and MN=33.4 Nm puts this squarely in the mid-power SIMOTICS S-1FL6 bracket — the kind of frame that drives packaging indexers, labelers, mid-size gantries and small-format CNC spindles when paired with a SINAMICS V90 in position or speed mode. The 90 mm shaft height is the mechanical footprint reference: a panel designer matching this slot needs the matching 90 mm S-1FL6 flange pattern, and the M0/MN gap (40 Nm vs 33.4 Nm) is the acceleration headroom the drive exploits during dynamic moves — about 20% overload margin between continuous and peak torque. IP65 with the sealing ring fitted means the motor body and the angle plug tolerate splash and light washdown — fine for food-adjacent conveyor sections and machine-tool cabinets, not for submerged or high-pressure washdown where IP67 or higher is the requirement. The 20-bit absolute encoder (12-bit multi-turn) delivers 1,048,576 counts per revolution and 4,096 turns of multi-turn retention without batteries — enough resolution for sub-arc-minute positioning on a V90 in servo-controlled mode without homing on every power-up. Plain shaft without holding brake — the load is held by the drive's regen or by a downstream mechanical brake; if the application needs a failsafe stop on power loss, a brake-equipped S-1FL6 variant has to be specified instead, because retrofitting a brake on a plain-shaft motor is not a field-mod.
Compliance, export, and packaging dimensions
RoHS compliance since 01-01-2018 and REACH Art. 33 duty-to-inform is on file — the standard EU substance-restriction posture, so the motor ships into CE-marked machinery without additional declaration paperwork. Export control markings are AL: N / ECCN: N, meaning no license required for the standard export destinations; the part is not on the U.S. dual-use or military lists.
Sourcing posture for an NRND servo motor
Group code R220 and product group 5183 are the internal Siemens classification handles — useful when a buyer cuts a PO or a declaration of conformity and needs to point the vendor at the exact catalog row the motor was specified under.
