Schneider Electric Altivar ATV350 Variable Speed Drives

Introduction

The Schneider Electric Altivar ATV350 is a variable speed drive family designed for precise on-machine motor control. It supports a broad range of industrial motor types while combining robust enclosure options, integrated functional safety, and modern industrial Ethernet connectivity.

Part Description

Altivar ATV350 variable speed drives are variable frequency drives (VFDs) for controlling the speed, torque, and direction of AC motors. The range is intended for synchronous, asynchronous, and permanent-magnet motors with power ratings from 0.75 kW to 11 kW on 380 V to 480 V supply systems.

These drives are well suited to machinery where compact, distributed motor control is needed near the equipment. Depending on the model, the ATV350 provides IP65/NEMA 4X or IP54/NEMA 12 environmental protection, helping it operate in industrial locations exposed to dust, washdown conditions, or other demanding conditions.

Key features include:

• Motor control for synchronous, asynchronous, and permanent-magnet motors
• Power range from 0.75 kW to 11 kW
• 380 V to 480 V operating range
• Integrated Safe Torque Off (STO) functionality
• Industrial Ethernet support
• Compatibility with Ethernet/IP, PROFINET, EtherCAT, and Modbus TCP networks
• IP65/NEMA 4X or IP54/NEMA 12 enclosure protection options
• On-machine installation capability

Applications

Potential applications for the Altivar ATV350 include:

• Conveyor and material-handling systems
• Packaging equipment
• Pumps and fluid-transfer equipment
• Fans and ventilation systems
• Mixers and agitators
• Industrial washing and cleaning machines
• Automated assembly equipment
• Machine-tool auxiliaries
• Food and beverage processing equipment
• Textile and printing machinery
• Warehouse automation systems
• General-purpose motor speed control

Industries

The ATV350 drive family can be used in a variety of industries, including:

• Manufacturing and factory automation
• Food and beverage processing
• Packaging
• Material handling and logistics
• Automotive manufacturing
• Pharmaceuticals and life sciences
• Water and wastewater treatment
• Chemical processing
• Plastics and rubber processing
• Pulp, paper, and printing
• Mining and industrial processing
• Building infrastructure and HVAC equipment

Usage Ideas

1. Networked Conveyor Section
   Use an ATV350 to control a conveyor motor in a packaging line, with speed commands and diagnostics exchanged through PROFINET or EtherNet/IP.

2. Variable-Speed Process Pump
   Control a 480 V pump motor to maintain flow or pressure while reducing energy use compared with constant-speed operation.

3. Washdown Packaging Machine Drive
   Install an IP65/NEMA 4X version directly on a food-processing or washdown machine to control a mixer, conveyor, or indexing mechanism.

Conclusion

Schneider Electric Altivar ATV350 variable speed drives provide a flexible solution for machine-level motor control from 0.75 kW to 11 kW. With support for several motor technologies, integrated Safe Torque Off, rugged enclosure options, and common industrial Ethernet protocols, they are suitable for connected, efficient, and safety-conscious automation systems.
