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 VW3M3403 is an analog encoder interface module for the Lexium 32 servo drive, giving a Lexium 32M drive an analog-signal encoder feedback input. It supports 1 Vpp, 1 Vpp/Hall and Hiperface encoder types through a single high-definition 15-pin SUB-D connector, with a 5 V or 12 V supply depending on the protocol in use.
The VW3M3403 is the analog-feedback option in the Lexium 32 encoder-interface family, reading 1 Vpp, 1 Vpp/Hall or Hiperface signals where the digital card (VW3M3402) handles BiSS/EnDat/SSI and the VW3M3401 handles resolvers. Supply voltage is set by the encoder type connected - 5 V for 1 Vpp and 1 Vpp/Hall, 12 V for Hiperface - matched to the servo motor's encoder datasheet before wiring.
Matches a Lexium 32M servo drive to an analog-signal servo motor encoder (1 Vpp, 1 Vpp/Hall or Hiperface) in machines or motor retrofits specifying analog rather than digital or resolver feedback.
