Description

The Schneider Electric ATV320D15N4C is a 1.5 kW(2 HP)compact variable frequency drive(VFD)from the Altivar 320 series,designed for simple yet robust motor control in industrial and commercial applications such as pumps,fans,conveyors,and mixers.Operating on a 380–480 V AC three-phase supply,it features an integrated EMC filter(Class C1),built-in braking transistor,and Safe Torque Off(STO)functionality compliant with IEC 61800-5-2,enabling safety-rated shutdown without power disconnection.With support for Modbus RTU,CANopen,and extensive I/O options,the ATV320D15N4C delivers energy savings,smooth motor acceleration,and seamless integration into automation systems—all in a space-saving DIN rail or panel-mount form factor.

Note:The model suffix”C”denotes inclusion of an integrated EMC filter(per EN/IEC 61800-3,Class C1 for residential/light industrial use).

Application Scenarios

In a food processing plant in Poland,a cooling tunnel conveyor required precise speed control to match product flow while minimizing energy use.Engineers installed the Schneider ATV320D15N4C to drive the 1.1 kW motor,leveraging its ramp profiling and multi-speed presets to adjust belt speed based on upstream sensor data.The built-in EMC filter eliminated radio interference with nearby wireless temperature loggers,and the STO function was wired to an emergency stop circuit—achieving PL d safety compliance without external modules.Over one year,the drive reduced energy consumption by 32%compared to direct-on-line operation,with zero downtime due to electrical faults—thanks to its 600 V surge protection and robust thermal design.

Technical Principles and Innovative Values

Innovation Point 1:Embedded Functional Safety Without Add-On Cards

The STO circuit is hardwired into the drive’s power stage—enabling certified safety stops using only two dry contacts,reducing cost and panel space.

Innovation Point 2:Adaptive Thermal Management

Internal algorithms dynamically adjust switching frequency and current limits based on heatsink temperature—maximizing uptime in hot enclosures.

Innovation Point 3:Plug-and-Play Commissioning with SoMove

Using Schneider’s free SoMove software,users auto-detect the drive,load application macros(e.g.,“Pump”),and tune parameters in minutes—no manual coding.

Innovation Point 4:Universal Global Compatibility

Accepts 380–480 V worldwide(including 400 V EU,415 V UK,460 V US)—ideal for multinational OEMs building standardized machines.

Application Cases and Industry Value

HVAC:Controls rooftop unit fans with night setback profiles,cutting seasonal energy use by 25%.

Water Treatment:Drives dosing pumps with analog feedback loops for precise chemical injection.

Packaging:Synchronizes labeling heads via Modbus speed commands from a PLC.

Material Handling:Enables soft-start on inclined conveyors to prevent product slippage.

In all cases,the ATV320D15N4C delivers reliability,energy efficiency,and regulatory compliance at a competitive price—making it a go-to solution for machine builders and plant engineers alike.
