Frequency inverter ATV320, 4kW, 380...500V, 3-phase, book-type ATV320U40N4B

Frequency inverter for motor control

This frequency inverter, model ATV320 from Schneider Electric, is a versatile device designed to control 3-phase synchronous and asynchronous motors. Its compact, book-style housing makes it easy to mount in automation cabinets, saving valuable space. Designed to operate at 380...500V and 50/60Hz, it offers a rated power of up to 4kW.

This inverter is not just about speed control – it's a comprehensive solution for a variety of industrial applications. The ability to work with motors up to 4kW / 5hp and advanced control functions make it an ideal choice for packaging machines, conveyors, mechanical actuators and lifting equipment. The integrated EMC filter ensures electromagnetic compatibility, and the IP20 protection rating protects against the ingress of solid objects.

Versatility and communication

ATV320 offers a wide range of communication possibilities, including Modbus, CANopen and PROFINET IO protocols. This makes it easy to integrate with existing EcoStruxure Machine automation systems from Schneider Electric. In addition, the ability to expand with communication cards (EtherCAT, Profibus DP V1) allows you to tailor the device to specific application needs.

Safety and functionality

Safety is a key aspect of this inverter. It has built-in safety functions (STO, SS1, SLS, SMS, GDL) that meet the requirements of IEC/EN 61800-5-1 and IEC/EN 61800-3 standards. These functions are configured using SoMove software, increasing flexibility and adaptation to specific machine safety needs. The integrated braking module (chopper) allows for effective motor stopping in emergency situations or during precise positioning.

Solid construction and reliability

The ATV320 inverter has been designed with demanding operating conditions in mind. The robust construction allows operation at temperatures up to 60°C and provides resistance to environmental factors (3C3 and 352 according to EN/IEC 60721-3-3). It is standardly adapted for heavy-duty (HD) applications with 1.5 x In overload for 60s every 10min and a maximum torque of 200% Mn, minimizing the risk of damage and ensuring long-term reliability. The dimensions of the device are 60 mm (width), 325 mm (height) and 245 mm (depth). It has six digital inputs, one digital output, three analog inputs and one analog output.
