Schneider Electric Altivar 31 drives

Overview

The Altivar 31 is Schneider Electric's earlier drive for simple machines, sold for years under the Telemecanique name. Schneider's product pages give single-phase 200...240 V and three-phase versions, sensorless flux vector control, six logic inputs, three analogue inputs and two relay outputs, with Modbus built in and CANopen through an adaptor. The ATV31H drives mount on a heat sink inside a cabinet; the ATV31C versions come in their own enclosure. Schneider lists them as discontinued and names Altivar Machine ATV320 references as replacements. TimControls quotes ATV31 drives against the reference and rating on the drive's label.
