Description

Brief Product Description

The Schneider Electric ATV320U55N4B is a 5.5 kW (7.5 hp) Altivar Machine variable speed drive designed to enhance the performance and safety of industrial equipment.² Featuring a space-saving book-style form factor and integrated safety functions, it delivers precise control for three-phase asynchronous and synchronous motors.³

Precision Motor Control and Machine Optimization

The Schneider Electric ATV320U55N4B belongs to the Altivar Machine ATV320 range, a series specifically engineered for Original Equipment Manufacturers (OEMs).⁴ This drive provides high-performance control for motors ranging from 380V to 500V AC.⁵ By incorporating advanced motor control algorithms, the unit ensures optimized torque performance and energy efficiency across a variety of mechanical applications.⁶ Its “book” format allows for side-by-side mounting, which significantly reduces the footprint within control cabinets while maintaining easy access to wiring terminals.⁷

Integrated Safety and Robust Environmental Protection

Operational safety is a cornerstone of the ATV320U55N4B architecture. The drive includes five integrated safety functions, such as Safe Torque Off (STO), which simplify machine certification and eliminate the need for extra external safety components. Furthermore, the internal circuit boards feature a specialized protective coating (3C3 class) to resist chemical corrosion and dust.⁸ This ensures the drive operates reliably in aggressive industrial atmospheres where temperatures may reach up to 50°C without derating, or up to 60°C with specific cooling considerations.⁹

Flexible Communication and Automation Integration

Schneider Electric has equipped the ATV320U55N4B with extensive connectivity options to facilitate seamless integration into modern automation architectures. The drive features onboard Modbus and CANopen protocols as standard, allowing for immediate communication with PLC systems.¹⁰ Furthermore, its compatibility with the SoMove software suite enables rapid commissioning, configuration cloning, and remote maintenance.¹¹ This versatility ensures that the drive supports complex machine movements and high-speed data exchange required for smart manufacturing and Industry 4.0 applications.
