Frequency inverter ATV320, 0.55kW, 380...500V, 3-phase, book-type ATV320U06N4B

Frequency inverter for a wide range of applications

The ATV320 frequency inverter from Schneider Electric is a versatile device designed to control synchronous and asynchronous motors. Designed for machine manufacturers (OEMs) and end-users, it offers reliable operation in simple and advanced industrial applications. This model, with a power of 0.55kW and a supply voltage of 380…500V, features a compact book-style design, making it easy to mount in control cabinets.

Functionality and Communication

The ATV320 provides extensive communication capabilities, including built-in CANopen and Modbus Serial line protocols. Additionally, functionality can be optionally extended with Ethernet IP, Modbus TCP, PROFINET, EtherCAT, DeviceNet, and PowerLink. This allows for easy integration with various automation architectures. It has 6 digital inputs, 1 digital output, 3 analog inputs, and 1 analog output, providing high flexibility in control configuration. Hardware connections include Industrial Ethernet (1), RS-485 (1), and an additional connection (1). Support for PROFIBUS and CAN protocols further increases its versatility.

Safety and Protection

The ATV320 inverter meets high safety standards, offering functions such as STO (Safe Torque Off), SS1 (Safe Stop 1), SLS (Safely Limited Speed), SMS (Safe Maximum Speed), and GDL (Guard Door Locking). The IP20 protection rating provides protection against contact and ingress of solid objects. The integrated EMC filter minimizes electromagnetic interference, ensuring stable system operation. The device is designed to operate at temperatures up to 60°C and meets environmental resistance standards 3C3 and 3S2 according to IEC 60721-3-3, making it suitable for demanding working conditions.

Applications and Advantages

The ATV320 inverter is used in a wide range of industrial and commercial machines, such as packaging machines, close-conveying systems, mechanical actuators, and lifting devices. Its versatility stems from its ability to control both asynchronous and synchronous motors. The compact book-style design saves space in control cabinets, and the ability to mount the GV2L08 protective device directly on the inverter optimizes installation costs and wiring. Additionally, the availability of functions such as motor autotuning and the ability to program with ATVLogic simplify the commissioning and configuration process.
