Technical Specifications Breakdown

Key parameters for the ATV71HD45N4 are listed below for quick reference:

Real-World Applications in Industrial Settings

The drive's 84-104 A current range and 380-480 V input flexibility make it suitable for conveyors, pumps, and fans in manufacturing plants. Its integrated EMC filter minimizes interference, critical for sensitive production lines. The wide frequency range allows precise speed control for processes requiring variable throughput.

Installation and Setup Guidance

Mount the unit vertically within ±10 degrees for proper cooling. Use shielded cable up to 100 m or unshielded up to 200 m for motor connections. Ensure the ambient temperature stays within -10 to 50 °C to avoid derating. The IP20 enclosure is intended for clean, dry indoor environments.

Maintenance and Reliability Tips

Periodically inspect the heat sink for dust accumulation and ensure airflow is unobstructed. The drive's thermal protection and overcurrent safeguards reduce unplanned downtime. For long-term reliability, verify that input voltage remains within 323-528 V limits.

Compatibility and Integration

This drive supports Modbus and CANopen communication protocols via RJ45 and SUB-D connectors, enabling seamless integration with existing automation networks. It is compatible with both asynchronous and synchronous motors.
