Product Overview
The Schneider ATV930D37N4 Altivar Process ATV930 Variable Speed Drive is an industrial AC drive used for controlling motor speed, torque, and operating performance in process automation and machine control applications. As part of the Altivar Process ATV930 family, it provides advanced variable-speed motor management for systems requiring accurate regulation and stable operation.
The ATV930D37N4 controls motor operation by adjusting output frequency and voltage, allowing motors to match actual process requirements instead of operating at fixed speed. This control method helps improve equipment response, reduce unnecessary mechanical stress, and optimize motor-driven processes.
The drive is commonly integrated into industrial applications involving pumps, fans, compressors, conveyors, and other continuous-duty equipment. It can communicate with PLC systems and industrial control networks, allowing centralized monitoring, parameter management, and automation integration.

Working Principle
The ATV930D37N4 operates by converting fixed-frequency AC power into a controlled variable-frequency output for driving AC motors.
A simplified operating path is:
AC Power Input → ATV930 Variable Speed Drive → Motor → Mechanical System
The drive receives operating commands from a control system, local interface, or communication network. Based on these commands, it regulates output frequency and voltage to adjust motor speed and torque.
During operation, the drive continuously manages motor performance according to the configured parameters and application requirements. This allows industrial equipment to maintain stable operation during load variations.
The drive acts as the control bridge between automation software and the physical motor-driven equipment.
Role in Industrial Motor Control Architecture
The ATV930D37N4 is positioned in the motor control layer of an industrial automation system.
A typical architecture can be represented as:
PLC / Control System → Communication Network → ATV930 Drive → AC Motor → Mechanical Equipment
| System Layer | Typical Function |
|---|---|
| PLC Controller | Executes automation programs |
| Communication Network | Transfers control commands and data |
| Variable Speed Drive | Regulates motor operation |
| AC Motor | Produces mechanical movement |
| Sensors | Provide process feedback |
| HMI / SCADA | Enables monitoring and operation |
The drive receives commands from the automation layer and converts them into controlled motor operation.
