Product Features
The Schneider ATV930D55N4 Altivar Process ATV930 Variable Speed Drive provides high-performance motor management functions for industrial equipment.
Key characteristics include:
- Schneider Altivar Process ATV930 variable speed drive
- Model ATV930D55N4
- Designed for industrial AC motor control applications
- Provides adjustable speed and torque regulation
- Supports stable operation under changing load conditions
- Integrates with PLC-based automation systems

The drive should be configured according to motor specifications, mechanical load conditions, control requirements, and automation system architecture.
Working Principle
The ATV930D55N4 controls motor operation by converting fixed-frequency AC input power into an adjustable output suitable for variable-speed motor operation.
A simplified operating path is:
AC Power Supply → ATV930 Variable Speed Drive → AC Motor → Mechanical Equipment
The drive receives speed or torque commands from a control system, local operation panel, or communication network. It processes these commands and adjusts the output frequency and voltage supplied to the motor.
By continuously regulating motor operation, the drive allows equipment to maintain the required process performance while reducing unnecessary mechanical stress caused by direct fixed-speed operation.
The internal monitoring and protection functions help maintain stable operation during different operating conditions.
Role in Industrial Motor Control Architecture
The ATV930D55N4 operates as the motor control layer between automation equipment and mechanical systems.
A typical architecture can be represented as:
PLC / Automation Controller → Communication Network → ATV930 Drive → Motor → Process Equipment
| System Layer | Typical Function |
|---|---|
| PLC Controller | Executes application control logic |
| Communication Network | Transfers commands and operating data |
| ATV930 Drive | Controls motor speed and torque |
| AC Motor | Provides mechanical power output |
| Sensors | Monitor process conditions |
| HMI / SCADA | Provides operation and visualization |
The drive converts digital control commands into precise motor operation for industrial processes.
Industrial Applications
The Schneider ATV930D55N4 is suitable for industrial systems requiring powerful and reliable variable-speed motor control.
| Application | Typical Use |
|---|---|
| Large Pump Systems | Flow and pressure management |
| Industrial Fans | Airflow regulation |
| Compressor Systems | Maintaining stable operation |
| Conveyor Equipment | Controlling material movement |
| Water Treatment Plants | Process equipment regulation |
| Manufacturing Facilities | Coordinated motor control |
| Process Industries | Continuous production applications |
| Heavy Industrial Equipment | Large motor management |
The final application depends on motor characteristics, load requirements, and process control objectives.
