The VW3A3E317 is a CC-Link communication card designed for Schneider Electric Altivar variable-speed drives. It provides a 2-wire RS 485 physical interface with selectable transmission rates from 156 kbps up to 10 Mbps, supporting up to 64 addresses on the CC-Link network. The card includes five status LEDs — one each for L.ERR (Error), L.RUN (Running), power, RD (Receive Data), and SD (Send Data) — plus a graphic display terminal for drive address and transmission speed configuration. Connection is via a removable screw connector with 5 contacts at 3.81 mm pitch, typical for panel wiring where the card may need to be swapped without disturbing the field wiring.
Schneider Electric has classified the VW3A3E317 as obsolete.
