Schneider Electric Altivar ATV61HD22N4 22kW Variable Speed Drive

Functional Overview

The Schneider Electric ATV61HD22N4 belongs to the esteemed Altivar 61 series, specifically engineered to manage variable torque applications in industrial buildings and infrastructure. This drive actively optimizes the performance of centrifugal pumps and fans by adjusting motor speed to meet actual demand. By utilizing advanced control algorithms, the unit significantly reduces mechanical wear and lowers energy consumption across high-power HVAC and water management systems.

Power Ratings and Performance

This variable speed drive operates on a three-phase supply voltage of 380V to 480V and delivers a rated power of 22 kW (30 hp). It maintains high operational stability even during temporary load fluctuations through its specialized torque control capabilities:

• Normal Duty Output: Supports a continuous current of 48A at 380V.
• Overload Capacity: Provides up to 110% of rated line torque for 60 seconds to handle startup inertia.
• Driving Capability: Controls both asynchronous motors and synchronous motors without speed feedback.
• Integrated Suppression: Features a built-in EMC filter (Class A) to mitigate electromagnetic interference in industrial environments.

Control and Communication Integration

The ATV61HD22N4 integrates seamlessly into complex automation architectures through its versatile communication ports and modular expansion slots. It simplifies system supervision by offering:

• Standard Connectivity: Includes built-in Modbus and CANopen protocols for immediate networking.
• Expansion Potential: Accommodates optional “I/O extension” cards and communication modules for Ethernet/IP, Profibus DP, and DeviceNet.
• Monitoring Tools: Features a multi-loader and Bluetooth link capability for wireless configuration and remote diagnostics.
• Safety Features: Incorporates the “Power Removal” safety function to prevent accidental motor restarts, complying with machine safety standards.

Application Environments

Because of its robust design and specialized pump/fan functions (such as “Sleep/Wake” and “Broken Belt” detection), this drive excels in specific industrial sectors. It is the preferred choice for:

• Large-scale HVAC systems in commercial and industrial facilities.
• Water treatment plants requiring precise pressure and flow regulation.
• Industrial ventilation and smoke extraction systems.
• Cooling tower management and boiler control.
