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 VW3M3402 is a digital encoder interface module for the Lexium 32 servo drive, giving a Lexium 32M drive a digital-output encoder feedback input. It supports BiSS, EnDat 2.2, A/B/I and SSI encoder protocols through a single high-definition 15-pin SUB-D connector, with supply voltages from 5 V to 12 V depending on the protocol used.
The VW3M3402 covers digital encoder feedback in the Lexium 32 encoder-interface family, handling BiSS, EnDat 2.2, A/B/I and SSI protocols on a single card instead of the resolver (VW3M3401) or analog (VW3M3403) variants. Supply voltage follows the protocol selected - 5 V for BiSS, EnDat 2.2 and A/B/I, 12 V for SSI - so the motor's encoder datasheet determines which supply mode the card is configured for.
Matches a Lexium 32M servo drive to a digital-protocol servo motor encoder (BiSS, EnDat 2.2, A/B/I or SSI) in machines built around digital feedback rather than resolver or analog encoder signals.
