Altivar 320 Frequency Converters – Reliable Motor Control

Schneider Electric Altivar 320 frequency converter is a compact device designed to control synchronous and asynchronous motors. It provides precise speed and torque regulation, making it an ideal solution for a wide range of industrial and commercial applications. Model ATV320U04M3C, with a power of 0.37 kW and a current of 3.3A, is particularly well suited for powering motors in machines such as packaging machines, short-distance conveyors, mechanical actuators, and lifting devices.

Design and Functionality

The converter is characterized by a solid construction and compact dimensions (72 mm width, 143 mm height, and 128 mm depth), which facilitates installation even in limited spaces. It has an IP20 protection class, protecting against the ingress of solid objects larger than 12.5 mm. The integrated braking module (chopper) increases the efficiency and safety of the system. The device supports both three-phase motors (input and output) and offers the possibility of operation in all quadrants of the coordinate system.

Communication and Expansion Options

Altivar 320 offers wide communication possibilities, including support for TCP/IP, PROFIBUS, CANopen, Modbus, and DeviceNet protocols. It has one RS-485 connection and one "other" connection, allowing integration with various automation systems. The ability to connect to a PC facilitates device configuration and diagnostics. Additionally, the availability of many expansion cards allows you to adapt the converter's functionality to specific application needs. Support for EtherNet/IP and PROFINET IO protocols ensures compatibility with modern control systems.

Safety and Reliability

The Altivar 320 converter has been designed with user safety in mind. The ability to implement safety functions such as STO (Safe Torque Off), SLS (Safely Limited Speed), SS1 (Safe Stop 1), SMS (Safe Maximum Speed), and GDL (Guard Door Locking) allows for the creation of safe control systems. The device is intended for industrial applications and is characterized by a durable construction enabling operation at temperatures up to 60°C (with derating). Compliance with IEC standards ensures high quality and reliability.
