Description

Product Description

The Schneider Electric ATV320U22N4C is a 2.2 kW (3 hp) compact variable speed drive from the Altivar Machine range, specifically engineered for high-performance control of 3-phase motors. It combines integrated safety features with a space-saving design to meet the rigorous demands of material handling, packaging, and textile machinery.

High-Performance Motor Control for Machine OEMs

The Schneider Electric ATV320U22N4C serves as a sophisticated frequency inverter within the Altivar Machine 320 series, providing precise regulation for both asynchronous and synchronous motors. Rated at 2.2 kW (3 hp), this drive operates efficiently across a broad supply range of 380V to 500V AC. Manufacturers prioritize this specific model because its compact physical footprint allows for high-density mounting within machine frames and control cabinets. By utilizing advanced sensorless flux vector control, the ATV320U22N4C delivers high dynamic response and exceptional torque stability, which remains consistent even at low operational speeds.

Engineered for Resilience and Functional Safety

Reliability in demanding industrial environments remains a core characteristic of the ATV320U22N4C hardware. The drive features protective coating on its printed circuit boards that complies with IEC 60721-3-3 class 3C3 standards, ensuring resistance to chemical corrosion and dust. Consequently, the unit maintains full operational capacity at ambient temperatures reaching up to 50°C, and up to 60°C with specific derating. Furthermore, the drive simplifies machine safety compliance by incorporating five embedded safety functions, including Safe Torque Off (STO). These integrated features reduce the need for external safety components, thereby lowering the total cost of system implementation.

Seamless Integration within EcoStruxure Architecture

System integrators benefit from the ATV320U22N4C’s native compatibility with the Schneider Electric EcoStruxure Machine architecture. This integration enables rapid commissioning and diagnostics through standardized software tools such as SoMove and Machine Expert. To ensure versatility across various automation networks, the drive supports a wide array of communication protocols and expansion accessories, including braking resistors and EMC filters. Whether managing conveyor systems or complex packaging lines, the Altivar ATV320U22N4C provides a robust, future-ready platform that enhances machine availability and process efficiency.
