Product Overview
The Schneider ATV930U55N4 Altivar Process ATV930 Variable Speed Drive is an industrial motor control device used to regulate the operating speed, torque, and performance of motor-driven equipment in process automation environments.
In many industrial applications, motors operate under changing production requirements. For example, pump systems may need different flow rates during different operating stages, ventilation equipment may adjust airflow according to environmental conditions, and conveyors may require variable speeds based on production demand. A variable speed drive allows these adjustments to be achieved through controlled motor operation.
The ATV930U55N4 belongs to the Altivar Process ATV930 series, which is commonly integrated into industrial control systems where motors need continuous speed adjustment, process monitoring, and communication with automation equipment.
Compared with traditional motor starting equipment, a variable speed drive manages motor behavior throughout the complete operating cycle. It controls acceleration, running speed, and stopping performance rather than only assisting with startup.
For maintenance and engineering teams, the ATV930U55N4 is typically considered part of the motor control section of an automation system. Troubleshooting should include the drive parameters, motor condition, incoming power, control signals, communication connections, and mechanical load.

Product Features
The Schneider ATV930U55N4 Altivar Process ATV930 Variable Speed Drive is applied in industrial environments requiring adjustable motor operation and integration with automation systems.
Key characteristics include:
- Schneider Altivar Process ATV930 series drive
- Model ATV930U55N4
- Controls motor speed and operating torque
- Supports industrial process equipment
- Suitable for variable-load motor applications
- Integrates with PLC and industrial control systems
- Supports controlled motor acceleration and stopping
- Used in pumps, fans, conveyors, and process machinery
The drive should be selected according to motor characteristics, application requirements, installation conditions, and the required control method.
Working Principle
The ATV930U55N4 works by converting the fixed electrical supply into a controlled output that allows the motor to operate at different speeds.
A typical application structure is:
Power Supply → ATV930U55N4 Drive → Motor → Mechanical Equipment → Process Operation
During operation, the drive receives commands from a PLC, HMI, communication network, or local control interface. It then adjusts output frequency and voltage according to the required motor operating condition.
In practical industrial use, the drive manages:
- Motor startup and acceleration
- Continuous speed adjustment
- Load response during operation
- Controlled stopping processes
- Motor performance according to process demand
The drive acts as the intermediate control device between the automation system and the motor, while the higher-level controller manages the overall production logic.
Role in an Industrial Automation System
The Schneider ATV930U55N4 operates within the motor control layer of an industrial automation architecture.
A typical system arrangement can be represented as:
PLC / Control System → ATV930U55N4 Drive → Motor → Industrial Equipment
The PLC or control system determines the required operating command, while the variable speed drive converts this command into controlled motor movement.
The ATV930U55N4 does not replace PLC processing functions or field measurement devices. Instead, it provides the electrical control required for motors used in automated production and process systems.
Industrial Applications
The Schneider ATV930U55N4 Altivar Process ATV930 Variable Speed Drive is commonly used in industrial applications where motor speed regulation is required.
| Application | Typical Use |
|---|---|
| Pumping Systems | Adjusting pump output according to process requirements |
| HVAC Equipment | Controlling fan speed and airflow |
| Water Treatment Systems | Managing motor-driven pumping equipment |
| Conveyor Lines | Regulating material transportation speed |
| Manufacturing Equipment | Controlling variable-speed machinery |
| Process Plants | Supporting continuous motor operation |
| Compressor Systems | Managing changing load conditions |
The final application depends on the motor type, mechanical system, and automation requirements.
Installation and Maintenance
Installation of the ATV930U55N4 requires correct configuration of electrical connections, motor data, and control parameters.
Recommended maintenance procedures include:
- Verify the drive model before installation
- Confirm motor electrical specifications
- Check input and output power wiring
- Inspect grounding connections
- Ensure proper ventilation around the drive
- Review parameter configuration
- Check communication interfaces
- Monitor fault records
- Verify motor operating conditions
- Document maintenance changes
When drive faults occur, engineers should inspect both the electrical and mechanical sides of the system. Incorrect parameters, motor overload, wiring problems, and external control issues can all affect drive operation.
