Product Overview
The Schneider ATV61HU22N4 Altivar 61 Variable Speed Drive is an industrial AC drive used for controlling motor speed and optimizing the operation of variable torque applications.
The Altivar 61 series is commonly applied in systems where motor performance needs to be adjusted according to process requirements. By controlling motor frequency and output power, the drive allows equipment such as pumps, fans, and HVAC systems to operate with improved flexibility and efficiency.
The ATV61HU22N4 serves as the interface between the electrical power supply, automation controller, and AC motor. It receives operating commands from the control system and adjusts motor operation based on application requirements.
For industrial maintenance teams, variable speed drives are important components in production equipment because their operating condition directly affects motor performance. During troubleshooting, engineers usually inspect drive parameters, motor wiring, communication status, cooling conditions, and connected mechanical equipment.

Product Features
The Schneider ATV61HU22N4 Altivar 61 Variable Speed Drive provides adjustable motor control for industrial applications requiring flexible speed regulation.
Key characteristics include:
- Schneider Altivar 61 series drive
- Model ATV61HU22N4
- Designed for AC motor speed control applications
- Suitable for variable torque equipment
- Supports integration into industrial automation systems
- Used for pump, fan, and process equipment control
- Provides adjustable motor operating speed

The drive configuration should be matched with motor specifications and the requirements of the controlled equipment.
Working Principle
The ATV61HU22N4 operates by converting fixed-frequency electrical power into adjustable-frequency output power for controlling AC motor operation.
A typical operating process is:
Power Supply → Altivar 61 Drive → AC Motor → Mechanical Equipment
The control system sends speed references or operating commands to the drive. The drive processes these commands and adjusts the output frequency and voltage supplied to the motor, allowing the motor speed to change according to process requirements.
For example:
- Pump systems can adjust flow according to demand.
- Fan systems can regulate airflow.
- Industrial equipment can achieve smoother acceleration and deceleration.
During operation, the drive continuously manages motor performance while monitoring internal operating conditions to support stable equipment operation.
Role in an Industrial Motor Control System
The Schneider ATV61HU22N4 functions as a motor control device within an automation system.
A simplified structure is:
PLC / Controller → Altivar 61 Drive → Motor → Mechanical Load
The PLC or control system provides operating instructions, while the drive converts and regulates electrical power delivered to the motor.
In industrial environments, the drive helps equipment achieve flexible operation, reduce unnecessary motor operation, and maintain better coordination between mechanical processes and automation systems.
Industrial Applications
The Schneider ATV61HU22N4 Altivar 61 Variable Speed Drive is commonly used in applications requiring variable-speed motor control.
| Application | Typical Use |
|---|---|
| HVAC Systems | Controlling fan and ventilation motors |
| Pumping Systems | Adjusting pump speed and flow |
| Water Treatment Equipment | Managing process pumps |
| Building Automation | Variable-speed equipment control |
| Industrial Fans | Regulating airflow systems |
| Process Equipment | Supporting continuous operation control |
| Manufacturing Systems | Controlling motor-driven machinery |
The final application depends on motor specifications and system requirements.
Installation and Maintenance
Proper installation and regular inspection help maintain stable drive operation.
Recommended maintenance procedures include:
- Confirm drive model before installation
- Verify incoming power connections

Technical FAQs
What type of applications is the ATV61HU22N4 most suitable for?
The ATV61HU22N4 is commonly used in variable torque applications such as pumps, fans, ventilation systems, and process equipment requiring adjustable motor speed.
How does the drive improve motor operation compared with direct starting?
The drive allows controlled acceleration, deceleration, and speed adjustment, helping reduce mechanical stress during equipment operation.
What parameters should be checked when commissioning an ATV61HU22N4?
Engineers should verify motor data, control mode, speed reference settings, communication parameters, and protection settings.
Why should the mechanical load be inspected during drive troubleshooting?
Because abnormal motor behavior may be caused by mechanical issues such as excessive load or equipment resistance rather than the drive itself.
