It carries a 20-bit absolute encoder with a feather key on the shaft, no holding brake, and IP65 protection with the sealing ring installed. This motor is designed to pair with SINAMICS V70 and V90 converters for positioning and motion-control axes in packaging, handling, and machine-tool applications. The IP65 rating with sealing ring means it withstands washdown environments — a common requirement in food-and-beverage or clean-in-place lines. ## Ratings that govern the fit At 2.5 kW and 11.9 Nm rated torque, this motor covers medium-duty axes — think indexing conveyors or rotary tables requiring sustained torque at moderate speed. The 2000 rpm base speed and 20-bit absolute encoder (0.34 arc-minute resolution per revolution) give the drive enough position feedback for closed-loop control down to a few arc-minutes of error. The shaft height of 90 mm and feather key (keyway) mean the motor mounts to standard metric-frame interfaces — confirm the load-side coupling and mounting bracket dimensions match the BOM before ordering. The absence of a holding brake shifts the stopping duty to the drive's dynamic braking or an external mechanical brake on the load side. Sourced through independent distribution channels.","metaTitle":"Siemens 1FL6090-1AC61-0LA1 SIMOTICS S-1FL6 Servo Motor","metaDescription":"Siemens SIMOTICS S-1FL6 servo motor, 2.5 kW, 400 V 3 AC, 2000 rpm, 20-bit absolute encoder, IP65.

The sealing ring must be seated correctly between the motor flange and the mating surface — without it, the IP rating drops to the motor's unprotected level.
