Product Overview
The Schneider ATV71HU22Y is an Altivar 71 variable speed drive used to control the speed, torque, acceleration, and deceleration of three-phase motors in industrial machinery. It belongs to the Altivar 71 drive family, a platform used in applications where motor speed needs to be adjusted according to the machine operating cycle rather than maintained at a fixed line frequency.
A variable speed drive sits between the electrical power supply and the motor. Instead of applying a fixed-frequency supply directly to the motor, the drive regulates the electrical output according to the commanded operating condition. This allows the motor to accelerate and decelerate under controlled conditions and enables the machine to operate at different speeds.
The ATV71HU22Y is suited to industrial equipment such as conveyors, pumps, fans, material-handling machinery, process equipment, and other motor-driven systems. In an installed system, the drive should be considered together with the motor, control signals, braking arrangement where applicable, protection devices, and machine load.

Working Principle
The ATV71HU22Y operates by regulating the electrical power supplied to the connected motor. A machine controller, operator command, or local drive command establishes the required operating condition. The drive then converts the incoming electrical power into a controlled motor supply appropriate to the commanded speed and operating state.
Power Supply → ATV71HU22Y → Controlled Motor Output → Motor → Mechanical Load
During acceleration, the drive manages the motor output so that the motor moves toward the commanded operating speed according to the configured drive parameters. During deceleration, the drive similarly controls the reduction in motor speed.
The drive can also receive operating feedback and control information from the wider machine system. Depending on the installation, this may include start/stop commands, speed references, status signals, or other control-system information.
The final machine response depends on the complete drive system. Motor characteristics, load inertia, mechanical transmission, acceleration and deceleration settings, and control commands all affect how the machine responds. For this reason, replacing the drive requires checking both the electrical configuration and the mechanical application rather than treating the drive as an isolated component.
Role in a Schneider Altivar 71 Motor Control Architecture
The ATV71HU22Y occupies the motor-drive layer between the plant or machine control system and the connected motor. It translates operating commands into controlled electrical motor power while allowing the machine control architecture to monitor drive status and operating conditions.
| System Layer | Typical Component | Function |
|---|---|---|
| Supervisory Layer | HMI / Operator Interface | Provides operator commands and displays drive or machine status |
| Control Layer | PLC / Machine Controller | Generates speed, start/stop, and process-related commands |
| Drive Layer | ATV71HU22Y | Regulates electrical power supplied to the motor |
| Motor Layer | Three-Phase Motor | Converts electrical power into mechanical rotation |
| Mechanical Layer | Gearbox / Coupling / Transmission | Transfers and adapts motor movement |
| Machine Load | Conveyor / Pump / Fan / Machinery | Performs the required industrial process |
| Feedback / Monitoring | Sensors / Drive Status Signals | Provides operating information to the control system |
Industrial Applications
| Application | Drive Role |
|---|---|
| Conveyor Systems | Controls motor speed according to material-handling requirements |
| Pumping Equipment | Adjusts motor operation to changing process flow requirements |
| Industrial Fans | Provides variable-speed operation for ventilation and process air systems |
| Material Handling | Controls movement speed of mechanical transport equipment |
| Packaging Machinery | Supports controlled motor movement during machine cycles |
| Manufacturing Equipment | Regulates motor-driven mechanisms within production machinery |
| Process Machinery | Adjusts motor speed to match changing process conditions |
| Machine Automation | Integrates motor-speed control with PLC and machine-control functions |
Installation and Maintenance
- Confirm the ATV71HU22Y model and verify that it matches the intended Altivar 71 application and existing drive configuration.
- Review the motor nameplate, drive documentation, electrical schematics, and machine-control drawings before installation.
- Isolate the incoming power and follow the approved lockout/tagout procedure before accessing the drive or motor circuit.
- Verify the incoming supply arrangement and confirm that the drive is suitable for the installed electrical system.
- Inspect the drive, terminals, connectors, cooling passages, and accessible components for damage, contamination, or signs of overheating.
- Verify the motor power connections and control wiring against the approved electrical documentation.
- Check the motor, coupling, gearbox, and driven mechanism for mechanical binding or abnormal resistance before commissioning.
- Enter or verify the applicable motor and drive parameters according to the installed motor and machine requirements.
- Check control commands, speed references, interlocks, and feedback signals before enabling the drive.
- Perform a controlled initial run at a safe operating condition and verify motor direction and basic speed response.
- Monitor the drive for abnormal current, vibration, temperature, faults, or unexpected acceleration and deceleration behavior during operation.
- Record the final drive parameters, motor information, wiring configuration, commissioning results, and maintenance observations for future service work.

Technical FAQs
What is the primary function of the ATV71HU22Y?
The ATV71HU22Y is a variable speed drive used to regulate the operation of a connected motor. It controls the electrical motor supply so that the motor can operate according to the required speed and machine operating conditions.
What should be checked when replacing an ATV71HU22Y?
The incoming electrical supply, connected motor, control wiring, motor parameters, machine load, communication or command interfaces, and applicable drive configuration should all be checked. The replacement drive should match the complete motor-control application rather than only the physical installation.
Why can a motor behave differently after a drive replacement?
Differences in motor parameters, acceleration and deceleration settings, command sources, speed references, control configuration, or mechanical load can change the machine response. Incorrect motor data or control settings can also result in abnormal operation or drive faults.
Can the ATV71HU22Y be used without a PLC?
A PLC is not necessarily required for every drive application. The drive can be incorporated into a broader machine-control system or operated using the control interfaces and command methods appropriate to the installation. The actual control arrangement depends on the machine design and required operating functions.
