Technical Specifications Breakdown

Key parameters for the ATV71HU22N4 are listed below for quick reference:

Application Versatility Across Industries

The ATV71HU22N4 supports both asynchronous and synchronous motors, making it suitable for conveyors, pumps, fans, and compressors. With a wide output frequency range of 0.1 to 599 Hz, it accommodates variable-speed processes requiring precise speed or torque control. The integrated EMC filter simplifies compliance with electromagnetic compatibility standards, reducing installation complexity in sensitive environments.

Installation and Setup Guidance

Mount the drive vertically within +/- 10 degrees for optimal cooling. Use shielded cable up to 50 m or unshielded up to 100 m for motor connections. Ensure the supply voltage remains within 323-528 V limits. The graphic terminal provides intuitive access to parameters, including acceleration/deceleration ramps (0.01 to 9000 s) and PI regulator adjustments.

Maintenance and Reliability

Operate within -10 to 50 °C ambient temperature without derating. The heat sink design supports effective thermal management. Periodic inspection of cooling fans and air filters is recommended. The drive includes protection against overcurrent, overvoltage, undervoltage, phase loss, and overheating, enhancing long-term reliability.

Compatibility and Integration

Built-in communication ports support Modbus and CANopen protocols, enabling integration with PLCs and SCADA systems. Optional communication cards add DeviceNet, EtherNet/IP, Profibus DP, and more. The drive also features 7 discrete inputs, 2 analog inputs, 1 analog output, and 2 relay outputs for flexible I/O configuration.

Selection Guide and Purchasing Advice

When evaluating this drive, consider your motor power (2.2 kW), voltage supply (380-480 VAC), and required control profile (sensorless flux vector or V/f). The ATV71HU22N4 is available from AutoDCSTech. Please verify current lifecycle status and availability before ordering.
