Product Overview
The Schneider ATV930D30N4 Altivar Process ATV930 Variable Speed Drive is an industrial variable frequency drive used for controlling the speed, torque, and operating performance of three-phase AC motors. It belongs to the Altivar Process ATV930 series and is designed for applications requiring stable motor control, process optimization, and integration with industrial automation systems.
The ATV930D30N4 adjusts motor operation by controlling output frequency and voltage, allowing equipment to operate according to process requirements rather than running at a fixed speed. This makes it suitable for systems where motor performance, energy consumption, and operational flexibility are important.
Compared with traditional motor starters, the drive provides more advanced control functions, including adjustable acceleration and deceleration, motor protection management, and communication with automation platforms.
The model is commonly used in industrial equipment such as pumps, fans, compressors, conveyors, and process machinery where reliable variable-speed operation is required.

Working Principle
The ATV930D30N4 controls AC motor operation by converting incoming electrical power into an adjustable output suitable for variable-speed operation.
A simplified operating path is:
Industrial Power Supply → ATV930 Variable Speed Drive → AC Motor → Mechanical Load
During operation, the drive receives control commands from local interfaces, PLC systems, or industrial networks. It processes these commands and adjusts the output frequency and voltage supplied to the motor.
By regulating motor speed and torque according to process requirements, the drive helps maintain stable equipment operation during changing load conditions.
The internal control functions also monitor operating conditions and provide protection features to support reliable motor performance.
Role in Industrial Motor Control Architecture
The ATV930D30N4 operates as the motor control layer between automation systems and mechanical equipment.
A typical architecture can be represented as:
PLC / Control System → Communication Network → ATV930 Drive → Motor → Industrial Equipment
| System Layer | Typical Function |
|---|---|
| PLC Controller | Executes automation sequences |
| Communication Network | Transfers commands and operating data |
| ATV930 Drive | Controls motor speed and torque |
| AC Motor | Provides mechanical power |
| Sensors | Provide process feedback |
| HMI / SCADA | Displays operating status |
The drive receives control instructions from the automation system and converts them into precise motor operating conditions.
Industrial Applications
The Schneider ATV930D30N4 is suitable for industrial systems requiring high-performance motor speed control.
| Application | Typical Use |
|---|---|
| Pump Systems | Flow and pressure adjustment |
| Fan Applications | Airflow regulation |

Technical FAQs
What type of applications require the ATV930D30N4 instead of a smaller ATV930 model?
The ATV930D30N4 is typically selected for applications with higher motor power requirements or larger mechanical loads where stable speed and torque control are needed.
How does this drive support process equipment performance?
By continuously adjusting motor operating parameters, the drive allows equipment such as pumps, fans, and compressors to respond more accurately to changing process conditions.
What should be checked before replacing an existing ATV930 drive?
Engineers should verify motor data, drive model compatibility, control wiring, communication settings, parameter backup, and installation conditions before replacement.
