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 Schneider Electric LXM18PDU15M2X is a Lexium 18 LXM18P compact-housing servo drive rated for 1.5 kW nominal output power from a single-phase 220...240 V supply. It delivers 9.5 A continuous output current at an 8 kHz switching frequency (29.2 A for 3 seconds peak), with integrated Modbus, digital I/O, analog I/O, PTI and PTO connectivity in an IP20 enclosure.
Size the LXM18PDU15M2X to the driven servo motor's continuous torque requirement: the 9.5 A continuous output current at 8 kHz is the figure to match against the motor's rated current, while the 29.2 A 3-second peak only covers short accelerations and should never be used for continuous-duty sizing. It sits between the 1 kW and 2 kW variants in the Lexium 18 PDU line on the same compact housing and 220...240 V supply — step down to the 1 kW variant where less continuous torque is needed, or move to a three-phase variant where the cabinet's incoming feed is three-phase. Its integrated Modbus, digital I/O, analog I/O, PTI and PTO connectivity covers pulse/direction step motion and analog setpoint control without an additional fieldbus card.
