Product details

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.

Frequently asked questions

How do I get current pricing and availability for VW3A3E312?

Submit an RFQ. The VW3A3E312 is sourced to order through independent distribution; availability and current pricing are confirmed at quote time, not published as live stock.

What is the closest pin-compatible alternative to VW3A3E312 in this component family?

Schneider Electric does not list an official successor for the VW3A3E312. A direct pin-compatible drop-in is not confirmed; migration typically involves evaluating the current Altivar drive generation and selecting a LonWorks option card or a protocol adapter for that platform.

What is VW3A3E312's listed topology?

TP/FT-10 (free topology). This means the LonWorks twisted-pair segment does not require a specific bus layout — star, daisy-chain, or mixed topologies are allowed within the 78 kbps signaling rate.
