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 6SL3120-2TE15-0AD0 is a SINAMICS S120 Double Motor Module in Bookize D-Type frame, providing two independent axes each rated 5.0 A and 2.7 kW from a 510-720V DC link. It includes Extended Safety Integrated support and the DRIVE-CLiQ cable, with internal air cooling and a 4 kHz pulse frequency.
The D-Type frame packs two independent 5.0 A axes (2.7 kW on IN, 2.3 kW on IH each) into one module footprint, the choice when driving two smaller motors from a single DC-link connection instead of the C-Type Single Motor Module's one 60 A axis. Each axis is commanded independently by the Control Unit over DRIVE-CLiQ, and the 650 Hz servo / 600 Hz V/f / 300 Hz vector output-frequency limits match the Single Motor Module family. Pick this module when the application needs two lower-power axes rather than one high-current axis.
Fits multi-axis SINAMICS S120 configurations, such as handling or packaging machines, where two motors each draw up to 5.0 A from a shared DC link and Line Module. Conductor cross-section runs 1.5 to 6 mm2 with up to 50 m of shielded motor cable per axis.
