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 1FL6024-2AF21-1AA1 is a SIMOTICS S-1FL6 servo motor rated 0.1 kW at 3AC 230V, with a rated speed of 3000 rpm, a rated torque of 0.32 Nm, and a 20 mm shaft height. It carries a TTL incremental encoder at 2500 increments per revolution on a feather-key shaft, an IP65-sealed enclosure, no holding brake, and is built to pair with SINAMICS V90 servo drives.
This variant has no holding brake, so on a vertical axis the load will drop on E-stop or a power loss unless an external brake is added elsewhere in the mechanism - pick a brake-equipped 1FL6 variant in the same frame for vertical mounting instead. At 0.32 Nm rated torque and 0.1 kW, this frame size targets low-inertia, light-load positioning axes rather than higher-torque points; step up to a larger 1FL6 frame if the application needs materially more torque at 3000 rpm.
Used as the motor half of a SINAMICS V90 servo axis in compact positioning tasks - small indexing stages, pick-and-place actuators, and light-load handling axes - where the 0.32 Nm / 0.1 kW rating and IP65 sealing fit a small-footprint drive.
