Product Overview
The Schneider ATV930D45N4 Altivar Process ATV930 Variable Speed Drive is an industrial AC motor drive used for precise speed, torque, and process control in demanding automation environments. It belongs to the Altivar Process ATV930 series and is designed for applications where motor operation needs to be adjusted according to real-time process requirements.
The drive controls motor performance by regulating output frequency and voltage, allowing connected equipment to operate efficiently under different load conditions. Compared with fixed-speed motor operation, variable speed control provides better flexibility for systems requiring frequent adjustment, controlled acceleration, or stable process performance.
The ATV930D45N4 is commonly applied in industrial equipment such as pumps, fans, compressors, conveyors, and production machinery. It can be integrated with PLC controllers, communication networks, HMI systems, and industrial monitoring platforms to support centralized automation management.

Working Principle
The ATV930D45N4 regulates AC motor operation by converting incoming electrical power into a controlled output with adjustable frequency and voltage.
A simplified operating path is:
AC Power Supply → ATV930 Drive → AC Motor → Mechanical Equipment
The drive receives commands from the control system and processes operating parameters before generating the appropriate motor output. By changing the frequency supplied to the motor, it controls rotational speed while maintaining suitable torque performance.
During operation, the drive monitors internal operating conditions and responds to process requirements through configured control functions. This allows motor-driven equipment to maintain stable operation even when system loads change.
Role in Industrial Motor Control Architecture
The ATV930D45N4 works as the motor management component between the automation control layer and field equipment.
A typical architecture can be represented as:
PLC / Automation Controller → Communication Network → ATV930 Drive → Motor → Process Equipment
| System Layer | Typical Function |
|---|---|
| PLC Controller | Executes control logic |
| Communication Network | Transfers commands and status information |
| ATV930 Drive | Controls motor speed and torque |
| AC Motor | Drives mechanical equipment |
| Sensors | Provide operating feedback |
| HMI / SCADA | Provides monitoring interface |
The drive converts automation commands into controlled motor operation for industrial processes.
