This Altivar 320 variable speed drive can feed 3-phase synchronous and asynchronous motors. Its compact form factor allows vertical stacking of drives inside machine frames. It works at a rated power up to 4kW / 5hp and a rated voltage from 380V to 500V AC. Its robust design with IEC 60721-3-3 class 3C3 coated printed circuit boards allows to extend machine availability in harsh environmental conditions, for example at ambient temperatures of up to 60°C without the need of additional cooling. It incorporates functions suitable for the most common applications, including torque and speed accuracy at very low speed, high dynamic performance with flux vector control without sensor and extended frequency range for high-speed motors. It also incorporates parallel connection of motors and special drives using the voltage/frequency ratio and static speed accuracy and energy saving for open-loop synchronous motors. The drive software includes 5 safety functions that help machines meet safety requirements, whether or not they are used in conjunction with a Preventa safety module. These safety functions are configured using SoMove software. Altivar Machine ATV320 was designed for Original Equipment Manufacturers (OEMs) that meets simple and advanced application requirements covered for packaging, material handling, textile, material working, mechanical actuators and hoisting. It conforms to international standards IEC/EN 61800-5-1 and IEC/EN 61800-3 (immunity and conducted and radiated EMC emissions). It is also CE, UL, CSA, NOM, EAC and RCM certified. Mounting accessories and external options (braking resistors, line chokes, motor chokes, additional EMC filters) are available with Altivar Machine ATV320 drives. The type of external accessories and options depends on the drive rating. It is designed to be mounted in vertical position (+/- 10 °) on a panel, thanks to 4 fixing holes. It is fully integrated inside Schneider Electric’s EcoStruxure Machine through DTM. It is possible to configure, control, and diagnose ATV320 drives directly in SoMachine and SoMove software by means of the same software brick (DTM).
