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 6SL3210-5FB10-4UA1 is a SINAMICS V90 servo drive rated for a 0.4 kW motor, accepting 200-240 V single/three-phase AC input at 45-66 Hz and delivering up to 2.6 A output current at 0-330 Hz. Housed in IP20 Size B (55 x 170 x 170 mm), it suits compact single-axis servo positioning applications.
At 0.4 kW motor power and 2.6 A max output current, this is the smallest frame (Size B) in the SINAMICS V90 range covered here - suited to light single axes rather than higher-inertia loads. The 200-240 V single/three-phase input (5.0 A single-phase vs 3.0 A three-phase) allows operation from either supply type; size the branch circuit to the higher single-phase draw. Step up to a larger V90 frame when the driven axis needs more than 0.4 kW.
Fits compact single-axis servo positioning on 200-240 V machines - pick-and-place, small conveyors, and packaging equipment needing a 0.4 kW servo axis.
