Schneider ATV320U22N4C ATV600 Variable Speed Drive

The Schneider Electric ATV320U22N4C represents a high-performance motor control solution within the Altivar Machine ATV320 family. Engineered specifically for three-phase asynchronous and synchronous motors, this drive provides a continuous power output of 2.2 kW (3 HP). Its compact, “compact-style” physical architecture allows industrial engineers to mount units side-by-side, which maximizes cabinet density and reduces overall enclosure costs. This model functions seamlessly within a broad supply voltage range of 380V to 500V AC, catering to diverse global power standards in industrial automation.

Robust Environmental Protection and Performance

To ensure long-term operational reliability, Schneider Electric manufactures the ATV320U22N4C with reinforced coated printed circuit boards. These boards comply with IEC 60721-3-3 class 3C3 standards, providing vital defense against chemical corrosion and high-humidity environments. Furthermore, the drive maintains peak efficiency even in ambient temperatures reaching 60°C. By utilizing sensorless flux vector control, the inverter achieves superior torque accuracy and speed regulation. This precision makes it a dependable choice for demanding motion sequences in packaging, material handling, and textile machinery.

Integrated Safety and Systems Connectivity

Safety integration serves as a cornerstone of the Altivar 320 series design. This drive includes five factory-embedded safety functions, most notably Safe Torque Off (STO), which enables machine builders to meet SIL3/PLe safety requirements without extra external hardware. Additionally, the unit facilitates rapid integration into the EcoStruxure Machine architecture through built-in Modbus and CANopen protocols. This connectivity allows maintenance teams to perform remote diagnostics and configuration using standardized tools like SoMove software, thereby reducing commissioning time and minimizing potential downtime.
