Product Overview
The Schneider ATV61HU55N4 Altivar 61 Variable Speed Drive is an industrial AC drive used for regulating the speed and operation of motor-driven equipment in automation and process control systems.
In industrial environments, many motor applications require flexible speed adjustment according to production conditions. The Altivar 61 series provides variable frequency control, allowing AC motors to operate according to changing load requirements instead of running at a fixed speed.
The ATV61HU55N4 is commonly integrated into applications such as pumps, fans, ventilation systems, and process machinery. It serves as the control interface between the power supply, automation controller, and motor, converting control commands into suitable motor operating conditions.
For engineers responsible for commissioning and maintenance, drive performance depends on correct parameter configuration, proper electrical installation, and suitable matching between the drive, motor, and mechanical load.

Working Principle
The ATV61HU55N4 operates by converting fixed electrical input into adjustable-frequency output power for AC motor control.
The basic operation sequence is:
Power Supply → Altivar 61 Drive → AC Motor → Mechanical Load
The automation system provides operating commands, including speed references and run instructions. The drive processes these signals and adjusts output frequency and voltage to control motor speed.
In practical applications:
- Pump systems can regulate flow according to process demand.
- Fan systems can adjust airflow while maintaining stable operation.
- Industrial machines can achieve smoother acceleration and deceleration.
The drive continuously monitors operating conditions and manages motor performance throughout the production process.
Role in an Industrial Motor Control System
The Schneider ATV61HU55N4 functions as a variable speed control unit within an industrial automation architecture.
A typical system configuration is:
PLC / Controller → Altivar 61 Drive → AC Motor → Equipment Load
The controller determines the required operating condition, while the drive manages electrical power conversion and motor response.
By controlling motor speed and torque, the drive helps improve process flexibility and allows equipment to operate more efficiently under different working conditions.
