Schneider ATV71HD22M3X Altivar 71 Variable Speed Drive 22 kW

Technical Specifications Breakdown

Key parameters for the ATV71HD22M3X are listed below for quick reference:

Precision Control for Demanding Industrial Applications

In modern manufacturing, managing motor speed and torque with high accuracy is critical for energy efficiency and process quality. The Schneider ATV71HD22M3X variable speed drive delivers robust performance for complex, high-power machines, offering sensorless flux vector control and closed-loop flux vector control with encoder feedback. This drive is engineered to handle asynchronous and synchronous motors, making it a versatile choice for applications requiring precise speed regulation and torque management.

Industry Applications and Performance Benefits

The sensorless flux vector control provides accurate torque down to zero speed, while the adjustable PI regulator allows fine-tuning of process parameters. With transient overtorque capability of 170% for 60 seconds and up to 220% for 2 seconds, the ATV71HD22M3X handles heavy load variations without tripping.

Installation and Setup Guidance

Mount the drive vertically within ±10 degrees to ensure proper cooling. Use shielded cable up to 100 m or unshielded up to 200 m for motor connections. The drive includes a graphic terminal for easy configuration of acceleration/deceleration ramps (0.01 to 9000 s) and motor control profiles. Ensure the ambient temperature stays within -10 to 50°C and avoid condensation. For installations at altitudes above 1000 m, derate the output current by 1% per 100 m up to 3000 m.

Maintenance and Reliability

Periodically inspect the cooling fan and heat sink for dust accumulation to maintain thermal performance. The drive features comprehensive protection against overcurrent, overvoltage, undervoltage, phase loss, and motor overheating. With an IP20 rating, it is suitable for clean indoor environments. The expected lifecycle of the relay outputs is 100,000 cycles. Always verify the current lifecycle status and availability with AutoDCSTech before ordering.

Compatibility and Integration

The ATV71HD22M3X supports Modbus and CANopen communication protocols via RJ45 and SUB-D 9 connectors. It can be integrated into existing automation networks using option cards for DeviceNet, EtherNet/IP, Profibus DP, and more. The drive is compatible with both synchronous and asynchronous motors, and its configurable I/O (2 analog inputs, 1 analog output, 7 discrete inputs, 2 relay outputs) allows flexible integration with PLCs and sensors.

Selection Guide and Purchasing Advice

When selecting a variable speed drive, consider the motor power, voltage, and environmental conditions. The Schneider ATV71HD22M3X is a reliable choice for 22 kW applications with 240 V AC three-phase input. For applications requiring EMC filtering, note that this model ships without an EMC filter. AutoDCSTech offers this drive with fast shipping and expert support to ensure you get the right component for your system.
