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 6SL3210-5FE12-0UA0 is a SINAMICS V90 servo drive sized for a 2.5 kW motor, taking a 380-480 V 3AC input and delivering 7.8 A rated output current (23.4 A max.) in an IP20 Size B enclosure measuring 100 x 180 x 220 mm. It pairs with a matching SIMOTICS S-1FL6 servo motor for closed-loop motion control.
The 7.8 A / 2.5 kW rating sizes this drive to the mid-range SIMOTICS S-1FL6 servo motors; the 3x overload margin to 23.4 A max. covers short acceleration peaks without stepping up to the next Size C frame. Size B's 100 x 180 x 220 mm footprint is the deciding factor when panel width is tight and the next power step up would not fit the enclosure. IP20 rating means it belongs inside a control cabinet, not exposed to washdown or dust.
Single-axis servo positioning on packaging, material handling, and machine tool axes sized around 2.5 kW, controlled via SINAMICS V90's PROFINET or pulse/analog interfaces.
