Schneider Electric Altivar Process ATV930 Variable Speed Inverter

Power Performance and Electrical Ratings

The Schneider Electric Altivar Process ATV930, identified by model code ATV930D75N4, is an industrial high-performance variable speed frequency inverter designed to optimize energy efficiency and deliver precise motor speed and torque regulation for three-phase electric motors. This heavy-duty power drive is rated to deliver a continuous output power of seventy-five kilowatts when connected to a nominal three-phase main line input ranging from three hundred and eighty to four百 and eighty Volts alternating current, making it suitable for driving high-capacity industrial machinery lines.

The inverter incorporates an integrated DC choke assembly that suppresses line current harmonics, protecting the power stage from supply line transients while satisfying standard electromagnetic compatibility criteria without requiring large external filter banks.

Advanced Motor Control and Smart Services

The ATV930 features advanced motor control algorithms that support open-loop or closed-loop voltage vector control, energy-saving U/f profiles, and precise permanent magnet motor synchronizations. The internal processing engine calculates real-time motor parameters dynamically, maintaining precise torque control across wide speed variations and delivering high breakaway torque for heavy mechanical start-ups.

As part of the Altivar Process family, the ATV930 incorporates embedded process management features, including integrated pump performance monitoring curves, fan efficiency calculators, and dry-run protection subroutines, allowing the drive to monitor overall fluid system performance directly without external sensor loops.

Integrated Ethernet Connectivity and I/O Slots

The ATV930D75N4 includes dual integrated Ethernet ports supporting Modbus TCP and EtherNet/IP protocols directly on its faceplate. This configuration supports network ring topologies and enables seamless integration into modern Industrial Internet of Things (IIoT) frameworks, allowing remote asset tracking, web-server configurations, and advanced diagnostics via standard web browsers.

The drive housing provides flexible terminal strips consisting of programmable digital inputs, safety-rated inputs for Safe Torque Off compliance (conforming to ISO 13849-1 PL e criteria), high-resolution analog inputs, and configurable relay outputs to manage complex local automation sequences.

Thermal Architecture and Ingress Robustness

The mechanical structure features a robust, wall-mountable enclosure engineered with separated cooling paths. The internal cooling fans draw heat away from the power electronics components while isolating the delicate control boards from the main airflow, preventing dust accumulation and moisture condensation from causing electrical faults over long service lifetimes.

Primary Industrial Fluid and Process Deployments

This seventy-five kilowatt frequency inverter is widely deployed within high-capacity wastewater pumping systems, industrial ventilation blowers, bulk material handling conveyors, oil-and-gas distribution pumps, compression blocks, and heavy processing mixers requiring precise torque control and advanced process logging functionality.
