Product Description

The ATV320U55N18C variable frequency drive is a 55kW motor controller designed for industrial automation, featuring robust integration capabilities. This VFD operates on a 3-phase 380-480V AC power supply with 50/60Hz frequency. It supports 3 analog/digital inputs and 2 relay outputs, enabling direct connection to sensors, PLCs, or external control modules. Communication interfaces include Modbus TCP/IP, CANopen, and EtherNet/IP for seamless network integration. Rated for operation between -10°C to +50°C, it suits harsh environments in sectors like manufacturing, water treatment, and material handling. Key advantages include high energy efficiency, compact design, and adaptive motor control algorithms. A minor drawback is its complex configuration for advanced settings. The ATV320U55N18C VFD excludes built-in battery backup but supports external braking resistor connectivity for dynamic motor braking.
