Schneider ATV320U55N4C Altivar Machine Variable Speed Drive 5.5 kW

Technical Specifications Breakdown

Key parameters for the ATV320U55N4C are listed below for quick reference:

Industry Applications and ROI

The integrated EMC filter reduces external filtering costs, while the built-in brake chopper and 4-quadrant operation enable energy recovery in overhauling loads. Compared to basic VFDs, the ATV320U55N4C offers sensorless flux vector control for better torque performance, reducing mechanical wear and downtime. Its Modbus and CANopen interfaces simplify integration into existing PLC networks, lowering installation and commissioning expenses.

Installation and Setup Guidance

Mount the drive vertically (+/- 10°) on a flat, non-flammable surface to ensure proper cooling. Maintain clearance around the unit for airflow; the drive requires 60 m³/h of cooling air. Use shielded cables for motor and control wiring to minimize electromagnetic interference. Configure parameters via the integrated keypad or software using Modbus/CANopen. Set the switching frequency between 2 and 16 kHz (4 kHz nominal) to balance acoustic noise and thermal performance. For ambient temperatures above 50°C, apply derating as specified.

Maintenance and Reliability

Periodically inspect the cooling fan and heat sink for dust accumulation, especially in environments classified as 3C3 (chemical) or 3S2 (solid particle) per IEC 60721-3-3. The drive’s thermal protection and input phase break detection safeguard against common faults. With an operating temperature range of -10 to 50°C (without derating) and a shock tolerance of 150 m/s² at 11 ms, this unit is built for industrial durability. Verify that the ambient air remains within -25 to 70°C during storage.

Compact Variable Speed Drive for Complex Machines

The Schneider ATV320U55N4C is a variable speed drive from the Altivar Machine ATV320 series, designed for complex machinery applications. This compact, wall-mountable drive delivers 5.5 kW motor power with a rated supply voltage of 380...500 V AC (3-phase) and a nominal output current of 14.3 A. Its integrated EMC filter simplifies installation, while the IP20 degree of protection suits enclosure-mounted setups. With 7 discrete inputs, 3 discrete outputs, 3 analog inputs, and 1 analog output, the drive offers flexible I/O for demanding automation tasks.

Compatibility and Integration

The ATV320U55N4C supports multiple fieldbus options via optional communication modules, including EtherCAT, PROFIBUS DP V1, PROFINET, Ethernet Powerlink, EtherNet/IP, and DeviceNet. Its slave CANopen interface and Modbus serial port enable seamless connectivity with Schneider and third-party controllers. The drive also features an adjustable PID regulator for closed-loop process control, making it suitable for pumps, fans, and conveyors.

Selection Guide and Purchasing Advice

When selecting a variable speed drive, consider the motor power, voltage, and environmental conditions. For higher overload requirements, verify the transient overtorque capability of 170-200%.
