This Altivar 320 variable speed drive can feed 3-phase synchronous and asynchronous motors. Its book form factor allows for a simple and compact installation in your automation cabinets. It works at a rated power up to 5.5kW / 7.5hp 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.
