This document is the programming manual for Traverse control Altivar 31pppT Variable speed drives for asynchronous motors, and it describes the features and characteristics of the product.
This manual provides the programming information required to configure and operate the Altivar 31pppT variable‑speed drive. It includes safety warnings, factory configuration data, function compatibility tables, and detailed menus for settings, I/O, control, and display.
The document also lists all communication variables for Modbus and CANopen, and explains how to assign inputs, outputs, and relays for the traverse‑control function. It should be used together with the standard Altivar 31 installation and programming manuals.
