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 6SL3130-7TE31-2AA3 is a SINAMICS S120 Active Line Module rectifying a 3 AC 342-528 V line to a DC 600 V link, rated 120 kW (200 A output) with a 292 A / 175 kW short-term maximum, built in the booksize frame with a 65 kA short-circuit strength rating. It works with an Active Interface Module to draw a near-sinusoidal line current and to feed regenerative energy back to the supply.
Paired with a matching Active Interface Module, this Active Line Module draws sinusoidal line current and feeds regenerative braking energy back to the supply — choose it over a Smart Line Module when the installation must meet strict line-harmonic limits or when the process needs continuous four-quadrant operation rather than occasional regenerative braking. At 120 kW rated / 175 kW short-term with a 292 A maximum, it covers combined motor-module loads beyond the smaller Line Module frame sizes in the same booksize range.
