Frequency inverter ATV320 3-phase 525/600VAC 50/60Hz 4kW 6.1A IP20 ATV320U40S6C

Frequency converters ATV320 – reliability and versatility in motor control

The ATV320 frequency converter is an advanced solution for precise control of asynchronous and synchronous motors. Designed by Schneider Electric, this device combines reliability, safety and durability, making it an ideal choice for a wide range of industrial and commercial applications. The ATV320U40S6C model, with a power of 4 kW and a supply voltage of 525-600 V AC, is particularly well suited for operation in demanding conditions.

Versatile application and robust construction

This converter is used in simple industrial machines, such as packaging machines, short-range conveyors, mechanical actuators and lifting devices. Its compact housing (140 mm wide, 184 mm high and 158 mm deep) allows for easy integration even in limited space. The robust construction allows operation at temperatures up to 60°C and in environments with increased resistance (3C3 and 3S2 according to EN/IEC 60721-3-3), ensuring high availability and minimizing the risk of failure. Standardly designed for heavy-duty applications (HD), with the possibility of 1.5 x In overload for 60 seconds every 10 minutes and a maximum torque of 200% Mn, it provides flexibility and minimizes the risk of incorrect selection.

Functions and communication

ATV320 offers a wide range of functions and communication possibilities. It has 6 digital inputs, 1 digital output, 3 analog inputs and 1 analog output. It supports communication protocols such as Modbus RTU, CANopen, PROFIBUS DP V1, PROFINET IO and DeviceNet. Built-in CANopen and Modbus RTU ports and FDT/DTM technologies enable deep integration with the EcoStruxure Machine automation architecture. Additionally, the ability to install expansion cards expands the functionality of the device. The integrated braking module (chopper) increases the safety and efficiency of the system.

Safety and flexibility

The ATV320 converter offers the possibility of using five certified safety functions: STO (Safe Torque Off), SLS (Safely Limited Speed), SS1 (Safe Stop 1), SMS (Safe Maximum Speed) and GDL (Guard Door Locking). The STO function ensures safe disconnection of the motor torque in emergency situations. The universal ATVLogic controller with over 50 function blocks allows for the implementation of various motor control applications. A wide range of supply voltage (230-600 VAC) reduces installation and power supply equipment costs.
