The VW3A3E312 is a LonWorks communication card for the Altivar 61 Plus drive series, transmitting at 78 kbps over a TP/FT-10 free topology network. It carries the LonMark 6010 profile for variable-speed motor drives, meaning it speaks the standard LonWorks object model — no custom gateway mapping needed if the building or line controller expects a LonMark-compliant drive node.
Schneider Electric has marked the VW3A3E312 as obsolete. No official successor order code is listed, so the replacement path depends on the drive generation — an Altivar 61 Plus on LonWorks may need a different comms card or a protocol adapter if migrating to a current drive family.
Integration Notes
The card connects via a single removable 3-way screw terminal — no special tooling, but verify the LonWorks polarity marking on the drive's option slot before wiring. Three LEDs (fault, service, status) plus two graphic display terminals for control word and reference received give on-card diagnostics without needing the drive keypad.
