PRODUCT OVERVIEW
The Altivar 31 (ATV31) adjustable speed AC drive controller incorporates the latest sensorless flux
vector technology into a compact, easy-to-use design for three-phase asynchronous squirrel-cage
motors. This versatile drive controller offers increased performance while maintaining cost-
effectiveness. The ATV31 drive provides advanced speed control capabilities for motors from
0.25–20 hp (0.18 to 15 kW). The controllers range from:
• 0.25 to 3 hp (0.18 to 2.2 kW), 208/230/240 V, single-phase input
• 0.25 to 20 hp (0.18 to 15 kW), 208/230/240 V, three-phase input
• 0.5 to 20 hp (0.37 to 15 kW), 400/460/480 V, three-phase input
• 1 to 20 hp (0.75 to 15 kW), 525/575/600 V, three-phase input
Industrial users and OEMs who specialize in material handling, pump, fan, packing, packaging, and
general purpose motor control applications will find the features and functions of the ATV31 drive
controller well suited for their use.
