Product Overview
The Schneider ATV930C25N4C Altivar Process ATV930 Variable Speed Drive is an industrial AC drive used to regulate the operating speed and torque of motor-driven equipment. It belongs to the Altivar Process ATV930 family and is intended for applications where motor control needs to be coordinated with process requirements and the wider automation system.
The drive manages the electrical output supplied to a compatible motor, allowing machinery to operate at controlled speeds rather than relying only on fixed-speed operation. This makes the ATV930C25N4C suitable for process equipment with changing flow, pressure, airflow, or material-handling requirements.
In an industrial installation, the drive typically works together with a motor, electrical protection equipment, PLC or DCS, and process instrumentation. Its role extends beyond basic speed adjustment because drive status, alarms, commands, and process feedback can form part of the overall control strategy.

Working Principle
The ATV930C25N4C controls motor operation by regulating the electrical power delivered to the connected AC motor.
A simplified arrangement is:
AC Power → ATV930C25N4C → AC Motor → Mechanical Load
The drive receives electrical power from the incoming supply and produces a controlled motor output. By adjusting the electrical operating conditions supplied to the motor, the drive can regulate motor speed and torque according to the application requirement.
For example, in a pumping system, process demand may vary throughout the day. Instead of keeping the motor at a constant maximum speed, the drive can adjust motor operation to match the required process condition.
The drive can also exchange commands, operating status, alarm information, and other relevant data with the plant automation system, allowing motor control to be coordinated with process logic.
Motor Control Architecture
The ATV930C25N4C sits between the electrical power system and the motor-driven process equipment.
Incoming Power → ATV930C25N4C → Motor → Process Equipment
The control relationship can be represented as:
PLC / DCS → Drive → Motor → Process → Sensors → PLC / DCS
| System Layer | Typical Component | Function |
|---|---|---|
| Electrical Supply | AC Power System | Supplies drive input power |
| Drive Layer | ATV930C25N4C | Regulates motor operation |
| Motor Layer | AC Motor | Produces mechanical power |
| Equipment Layer | Pump / Fan / Compressor | Performs process work |
| Instrumentation | Pressure / Flow / Process Sensors | Provides process feedback |
| Control Layer | PLC / DCS | Executes process control logic |
| Operator Layer | HMI / SCADA | Provides monitoring and operator interaction |
This arrangement allows the drive to handle motor-control functions while the PLC or DCS manages the broader process sequence.
Industrial Applications
The ATV930C25N4C is suitable for large motor-driven systems where variable-speed operation can improve process control.
| Application | Typical Use |
|---|---|
| Water Pumping | Flow and pressure regulation |
| Wastewater Treatment | Pump and process equipment control |
| Industrial Fans | Airflow regulation |
| HVAC Equipment | Variable-speed fan operation |
| Compressors | Capacity and process control |
| Conveyors | Controlled material transport |
| Process Plants | Continuous-duty motor control |
| Manufacturing Machinery | Adjustable-speed production equipment |
For pumps and fans in particular, matching motor speed to actual process demand can be more effective than continuously operating equipment at a fixed speed.
Installation and Maintenance
The physical size and weight of the ATV930C25N4C should be considered before installation.
Recommended procedures include:
- Confirm the complete ATV930C25N4C model number.
- Verify drive and motor compatibility.
- Confirm the incoming electrical supply requirements.
- Check motor cable specifications and termination.
- Provide suitable grounding and protection.
- Verify the mounting structure can support the drive.
- Plan lifting and positioning procedures before installation.
- Provide adequate ventilation and heat dissipation.
- Maintain suitable service clearance.
- Inspect power and control connections.
- Verify communication wiring.
- Check motor rotation during commissioning.
- Review acceleration and deceleration parameters.
- Monitor drive alarms during initial operation.
- Inspect cooling paths and electrical connections during maintenance.
Because the listed unit weighs 203 kg, mechanical handling should be planned as part of the installation procedure rather than treated as a routine cabinet component.
