Schneider Electric ATV320D15N4C – 15 kW Variable Speed Drive for 380–500 V 3-Phase Motors

The Altivar Machine ATV320D15N4C is a robust, factory-ready VFD built for packaging lines, conveyors, hoists, and general machinery. From my experience, this model hits the sweet spot when you need a compact 15 kW drive with reliable torque at low speed, embedded Modbus/CANopen, and an integrated EMC filter to keep panel design tidy. You might notice that in many cases it replaces older ATV31/312 footprints with minimal rewiring.

Key Features

• 380–500 V 3-phase supply – Sized for 15 kW normal-duty applications (typically ~11 kW heavy-duty), covering most mid-power machines.
• Integrated EMC filter – The “C” suffix means the filter is built in, which usually saves space and cuts wiring complexity.
• Control modes for real-world jobs – V/f and sensorless vector control (SVC) for stable low-speed torque and efficient ramping.
• Safety built-in – Safe Torque Off (STO) typically to SIL3 / PL e, helping you meet machine safety requirements without extra hardware.
• Embedded communications – Modbus RTU and CANopen onboard; optional cards for EtherNet/IP, Modbus TCP, PROFINET, PROFIBUS DP when needed.
• Flexible I/O – Standard digital and analog I/O for start/stop, speed reference, and alarms; relay contacts for external signaling.
• Wide environment tolerance – Operates in most panels at -10…50°C without derating (up to ~60°C with derating), which seems to be what most OEMs expect.
• Compact mechanical design – IP20 open style for cabinet mounting, with optional kits for higher protection inside the enclosure.

Technical Specifications

Application Fields

This drive is commonly selected for mid-power machinery where uptime and compact control panels matter:

• Packaging and labeling lines – precise speed trim for infeed/outfeed conveyors, sealers, and indexing drives.
• Material handling – roller conveyors, sorters, and lifts that need steady torque and soft start/stop.
• Pumps and fans – energy-saving V/f control with low harmonics and simple PI regulation.
• Machine tools and woodworking – variable spindle/aux drives with fast acceleration.
• Textile and printing – speed synchronization over Modbus or CANopen, with clean EMC behavior inside the cabinet.

A maintenance manager from a food plant told us their switch to ATV320 on a dough conveyor “basically eliminated nuisance trips” when the line ramps up fast after a stop. That’s pretty typical when SVC is tuned right and wiring is neat.

Advantages & Value for Procurement

• Reliability – Mature Altivar platform; less downtime and fewer nuisance faults in most installations.
• Compatibility – Embedded Modbus/CANopen plus widely available option cards make integration straightforward.
• Cost control – Integrated EMC and STO lower accessory count; typically reduces panel footprint and wiring hours.
• Lifecycle support – Global Schneider Electric service network; spares and accessories are easy to source.

Installation & Maintenance

• Cabinet – Mount in a metal enclosure (IP54 or better for dusty/moist areas). Keep vertical clearance for airflow; avoid hot spots near braking resistors.
• Wiring – Use screened motor cables and proper PE bonding. Separate control wiring from power. Follow EMC best practices to leverage the integrated filter.
• Protection – Provide upstream circuit breaker/fuses and an input line reactor where harmonics or weak grids are a concern.
• Ventilation – Maintain ambient -10…50°C for full rating; derate or add cooling above that. Keep filters clean.
• Commissioning – Run auto-tuning (motor nameplate data) for best SVC torque. Verify STO wiring and safety category if used.
• Routine care – Periodically check fan operation, tighten terminals, clean dust, and back up parameters. Firmware updates can be applied when advised by Schneider notes.

Quality & Certifications

• Conformity: CE, UL/cUL, EAC, RoHS, REACH (typical for ATV320 series)
• Functional safety: STO up to SIL3 / PL e (wiring and integration dependent)
• Manufacturing: Schneider Electric quality system (ISO 9001)
• Manufacturer’s warranty: Schneider Electric standard policy (commonly ~18 months from shipment)

Supporting Components (Optional)

• Braking resistor for fast deceleration on high-inertia loads
• Input line choke / output motor choke to improve power quality and motor cable lengths
• Remote keypad/display and door-mount kit for easy operator access
• Fieldbus communication cards (EtherNet/IP, Modbus TCP, PROFINET, PROFIBUS DP)
• External EMC accessories and NEMA/IP kits depending on the enclosure standard

If you share your motor nameplate, cable length, and duty profile, we’ll verify the exact choke/resistor sizing so it’s right the first time.
