Technical Specifications Breakdown

Key parameters for the ATV71HD22N4 are listed below for quick reference:

Robust Variable Speed Drive for Demanding Applications

The Schneider Electric ATV71HD22N4 is a variable speed drive from the Altivar 71 series, engineered for precision control of asynchronous and synchronous motors in complex, high-power machinery. With a motor power rating of 22 kW (30 hp) and a 3-phase input voltage of 480 V AC, this drive delivers reliable performance for industrial automation tasks.

Industry Applications

Its integrated EMC filter and support for both asynchronous and synchronous motors make it suitable for applications requiring precise speed and torque control. The ATV71HD22N4's ability to handle transient overtorque of 170% for 60 seconds ensures it can manage sudden load changes common in material handling and processing industries.

Installation & Setup Guidance

Mount the drive vertically within ±10 degrees to ensure proper cooling via the integral heat sink. Use shielded cable up to 100 m or unshielded up to 200 m for motor connections. For enclosure mounting, follow the provided cable type specifications (e.g., NEMA Type 1 kit with UL 508 cable). Ensure the ambient temperature remains between -10°C and 50°C during operation to avoid derating.

Maintenance & Reliability

Inspect the drive periodically for dust accumulation on the heat sink and ensure airflow is unobstructed. The drive's protection features include thermal protection, overcurrent, and phase loss detection, which help prevent damage. Store the unit within -25°C to 70°C when not in use, and maintain relative humidity between 5% and 95% without condensation.

Compatibility & Integration

The ATV71HD22N4 supports Modbus and CANopen communication protocols via RJ45 connectors and a SUB-D 9 connector. It accepts various option cards (e.g., Profibus DP, EtherNet/IP, DeviceNet) for network integration. The drive includes 2 analog inputs, 1 analog output, 7 discrete inputs, and 2 relay outputs for flexible control system connectivity.

Selection Guide & Purchasing Advice

When selecting this drive, verify that your motor power and voltage match the 22 kW, 480 V AC 3-phase rating. Please verify current lifecycle status and availability with AutoDCSTech before ordering, as this model has a phase-out status.
