Siemens 1FL6090-1AC61-0LG1 — spare-part servo for SINAMICS V70 & V90
The 1FL6090-1AC61-0LG1 is a SIMOTICS S-1FL6 servo motor, designated as a spare part, that runs on 400 V three-phase AC and delivers 2.5 kW at 2000 rpm rated speed. Rated torque is 11.9 Nm with a peak standstill torque of 15 Nm, making it suitable for direct-drive or geared motion axes in machine tools, packaging lines, and material handling where the SINAMICS V70 or V90 drive family provides the commutation.
Encoder, shaft, and sealing — what the 20-bit absolute and IP65 mean for the line
A 20-bit absolute encoder (single-turn or multi-turn, depending on the drive parameterisation) eliminates the need for a homing routine on every power-up — the axis position is known immediately after the drive bus cycle starts. The plain shaft without holding brake means this variant is intended for vertical axes where an external brake or counterbalance handles the load-holding; the IP65 rating with the supplied sealing ring lets it withstand washdown in food or beverage lines without a secondary cover.
