Product Description

The Altivar 71 HD18N4Z (ATV71HD18N4Z Inverter) is a Heavy Duty Variable Drive designed for high-performance industrial applications such as mining, material handling, and heavy machinery. It features 3-phase input and output, supporting direct integration with up to 4 external expansion modules. Communication interfaces include Modbus, CANopen, and Ethernet/IP for seamless system integration. Operating within a voltage range of 380-480V AC (±10%) and a temperature range of -10°C to +50°C, it ensures reliability in harsh environments. Key advantages include robust overload capacity, advanced thermal management, and customizable motor control algorithms. Its compact design incorporates a 2.4-inch LCD display for parameter monitoring. However, it lacks built-in battery backup and requires external cooling in extreme conditions. The drive does not support sensorless vector control beyond 200Hz operation.
