VFD vs Servo Drive: Key Differences
A side-by-side comparison of VFD and servo drive motor type, feedback, dynamic response, overload rating, cost, and applications for industrial engineers.
The Siemens 1FL6090-1AC61-2AA1 is a SIMOTICS S-1FL6 servo motor rated 2.50 kW at 2000 rpm on a 3AC 400 V supply, with 11.9 Nm rated torque, 35.70 Nm maximum torque, and a 2500 incr/rev incremental encoder. It has shaft height 90 mm, IP65 protection with sealing ring, and pairs with SINAMICS V70/V90 converters.
The 11.9 Nm rated torque and 90 mm shaft height put this motor a step above the smaller shaft-height-65 frames in the same family, sized for higher-load axes while staying within the SINAMICS V70/V90 drive range. It ships without a holding brake, so vertical or overhauling axes need an external brake or a brake-equipped sibling motor. The 2500 incr/rev incremental encoder, not an absolute type, ties this variant to V70/V90 rather than SINAMICS S120/S210.
Drives higher-torque servo axes on packaging, material-handling, and general motion-control machinery built around SINAMICS V70/V90, where a shaft-height-90, 2.5 kW motor matches the load.
