Frequency inverter ATV320, 3kW, 380...500V, 3-phase, book-type ATV320U30N4B

Frequency inverter for a wide range of industrial applications

This Altivar 320 frequency inverter is a versatile solution for controlling 3-phase synchronous and asynchronous motors. Its compact, book-style design simplifies mounting in automation cabinets, saving valuable space. Designed to operate at voltages from 380V to 500V AC and power up to 3kW, it is ideal for packaging machines, conveyors and other equipment requiring precise speed control. The integrated EMC filter ensures electromagnetic compatibility, minimizing interference in the installation.

Functionality and communication

The inverter offers a wide range of communication possibilities, including CANopen, Modbus RTU and EtherNet/IP protocols. This makes it easy to integrate with various automation systems and allows for remote monitoring and diagnostics. It has 6 digital inputs, 1 digital output, 3 analog inputs and 1 analog output, allowing flexible adaptation to specific application needs. It also supports PROFIBUS and DeviceNet protocols. The RS-485 hardware connection allows for serial communication, and the presence of one Industrial Ethernet connection increases integration possibilities with modern industrial networks.

Safety and reliability

The Altivar 320 has been designed with safety and reliability in mind. It meets IEC/EN 61800-5-1 and IEC/EN 61800-3 standards regarding electromagnetic interference emissions and immunity. The ability to integrate with the Preventa safety module (optional) and built-in safety functions (STO, SLS, SS1, SMS, GDL) allow for the creation of safe and compliant control systems. The robust construction allows operation at temperatures up to 60°C and in environments with increased humidity (IP20 protection). The inverter is adapted for heavy-duty applications (HD), offering 1.5 x In overload for 60 seconds every 10 minutes and a maximum torque of 200% Mn.
