0.75 kW, 3000 rpm, 20-bit absolute encoder — what these ratings mean for the cell
The 1FL6044-1AF61-0LG1 is a spare-part SIMOTICS S-1FL6 servo motor from Siemens, rated 0.75 kW at 3000 rpm nominal speed. The 20-bit absolute encoder (12-bit multi-turn) gives position feedback down to 0.00034° per count — enough for high-precision indexing without a separate encoder cable or battery-backed multi-turn. Rated torque MN is 2.39 Nm; stall torque M0 is 3.5 Nm. The gap between M0 and MN tells you the motor has thermal headroom for short-duration overloads — useful for acceleration or intermittent peak loads in a pick-and-place or palletizing cycle. IP65 with the sealing ring means the motor body and shaft seal resist washdown and dust ingress. In a food, beverage, or wet machining environment, this avoids premature bearing corrosion and encoder contamination.

Drive pairing — SINAMICS V70 and V90
The motor is explicitly listed as compatible with SINAMICS V70 and V90 converters. This means the encoder interface, motor feedback cable, and power connector pinout are matched out of the box — no adapter cables or custom wiring needed for commissioning. Shaft height is 45 mm with a plain shaft and tolerance N. The plain shaft (no keyway) suits direct coupling or collet-style connections where you need zero backlash; tolerance N keeps the fit consistent for repeatable mounting.
