Operating from a 3AC 400 V bus, the motor delivers Pn = 1 kW at Nn = 2000 rpm with M0 = 6 Nm stall and MN = 4.78 Nm rated — so it covers the mid-power 1FL6 slot where positioning axes and small feed drives live. The holding brake keeps the axis locked when the drive is disabled, which matters on vertical or inclined loads where back-driving would lose position the moment the controller drops enable. ## Encoder feedback and loop cleanliness The 20-bit absolute encoder (12 bits multi-turn) resolves to roughly 1.09 arc-minutes per count — fine enough for sub-degree positioning repeatability without forcing the controller into interpolated micro-steps, and the multi-turn tracks absolute shaft position across power cycles so the axis does not need to home on every restart. Feather-key shaft with tolerance N and an angle plug for the power and feedback connection: the plug orientation matters at panel-build time because once the motor is mounted, re-aiming the connector means rotating the housing on the flange. ## IP65 with sealing ring — washdown-adjacent, not submerged IP65 with the sealing ring correctly seated on the flange keeps dust and low-pressure water jets out of the housing — adequate for machine-tool enclosures, packaging lines and light washdown zones, but it is not IP67, so high-pressure cleaning or full submersion is outside the rated envelope. The seal is at the flange mating face, not the cable exit; cordset selection has to match the same IP class or the wet end of the run leaks past the connector before the motor body ever sees water. ## V70 / V90 pairing and what to verify at commissioning The motor is listed as compatible with the SINAMICS V70 and V90 converter families — firmware auto-identifies the 1FL6 via the electronic nameplate, so motor ID and encoder type come up without manual parameter entry as long as the feedback cable is the catalogued variant for that drive. Holding-brake logic is wired through the drive's brake output; confirm the brake release timing parameter against the axis' safe-stop requirement, because a brake that releases late on a vertical axis stalls the drive and a brake that releases early drops the load. ## NRND — last-time-buy window, no official successor named Lifecycle status on the official record is NRND — the part is approaching end of production rather than actively promoted, but it is not yet discontinued and existing V70 / V90 installations still need it for spares and replacement axes. The product carries product class C: made-to-order, non-returnable, non-reusable — which is the Siemens designation for configured motors produced against a specific order and not kept as general stock.","metaTitle":"Siemens 1FL6062-1AC61-2LB1 Servo Motor, 1 kW, 6 Nm, IP65","metaDescription":"Siemens SIMOTICS 1FL6062-1AC61-2LB1 servo motor, 1 kW at 2000 rpm, 6 Nm M0, 400 V, IP65 with holding brake.
