Product Overview

The Schneider ATV930C25N4 Altivar Process ATV930 Variable Speed Drive is a high-power AC drive for controlling the speed, torque, and operating behavior of three-phase motors in demanding industrial applications. It belongs to the Altivar Process ATV930 family, which is used in applications where motor control, process regulation, energy management, and equipment protection need to work together.

The ATV930C25N4 is particularly suited to larger motor-driven systems. Instead of operating a motor directly at a fixed speed, the drive regulates motor operation according to the required process conditions. This makes it useful for pumps, fans, compressors, conveyors, and other continuous-duty machinery.

In a plant environment, the drive normally sits between the incoming electrical supply and the motor, while exchanging operating commands and process information with the automation system. Its installation therefore involves not only motor sizing, but also power distribution, control wiring, communication, cooling, protection, and cabinet arrangement.

Technical Specifications

Product Features

The ATV930C25N4 is intended for large industrial motor-control installations where stable variable-speed operation and process coordination are required.

Key characteristics include:

• Schneider Altivar Process ATV930 variable speed drive
• Model ATV930C25N4
• Designed for industrial AC motor control
• Suitable for variable-speed applications
• Supports controlled motor acceleration and deceleration
• Suitable for demanding continuous-duty applications
• Can be integrated with industrial automation systems
• Applicable to pumps, fans, compressors, conveyors, and process machinery
• Suitable for process-oriented motor control
• Designed for large-scale industrial installations
• Suitable for applications requiring coordinated motor and process control

The relatively large physical size and 203 kg weight should be considered when planning cabinet installation, lifting, transportation, and service access.

Working Principle

The ATV930C25N4 controls the electrical power delivered to the motor rather than simply switching the motor on or off.

A simplified power and control path is:

AC Power Supply → ATV930C25N4 → Three-Phase Motor → Industrial Process

The drive receives incoming electrical power and generates a controlled output for the motor. By regulating the motor’s electrical operating conditions, the drive can adjust motor speed and torque to match the process requirement.

For example, a pump does not always need to operate at full speed. The drive can adjust motor operation according to the required flow or pressure, reducing unnecessary mechanical and electrical loading.

On the control side, the drive can exchange operating commands, status information, alarms, and process-related data with the automation system. This allows motor control to become part of a larger PLC, DCS, or process-control strategy.

Role in an Industrial Motor Control Architecture

The ATV930C25N4 occupies the power-control layer between the plant electrical supply and the motor.

Power Supply → ATV930C25N4 → Motor → Mechanical Load

At the automation level:

PLC / DCS → Drive Control → Motor → Process Equipment → Feedback → Control System

This architecture allows the drive to handle the fast electrical and motor-control functions while the PLC or DCS manages the wider process sequence.

Industrial Applications

The ATV930C25N4 is suited to high-power industrial machinery where variable-speed motor control can improve process regulation and operating efficiency.

For pump and fan applications, variable-speed operation can be particularly useful because process demand frequently changes during normal plant operation.

Installation and Maintenance

Because the ATV930C25N4 is a large industrial drive, installation planning should cover electrical, mechanical, thermal, and service requirements.

Recommended checks include:

• Confirm the complete ATV930C25N4 model number.
• Verify the motor and drive application compatibility.
• Confirm incoming power requirements.
• Check motor cable routing and termination.
• Provide suitable grounding and protective arrangements.
• Verify cabinet or installation structure can support the drive weight.
• Allow adequate ventilation and heat dissipation.
• Maintain sufficient service access around the equipment.
• Check control and communication wiring.
• Verify motor rotation before commissioning.
• Review acceleration and deceleration settings.
• Check drive alarms and operating status.
• Inspect power connections during scheduled maintenance.
• Keep cooling paths free from dust and contamination.

For a large drive installation, mechanical handling is also important. With a listed weight of 203 kg, lifting and positioning should be planned before the equipment is moved into the final installation location.

Related Components

The ATV930C25N4 normally operates as part of a complete motor-control system rather than as an isolated device.

Correct sizing of the motor, drive, protection equipment, and associated electrical components is essential for a complete installation.

Recommended Related Models

When replacing an ATV930 drive, the motor rating, supply characteristics, application load, installation method, control requirements, and existing system configuration should be checked rather than selecting a model based only on physical dimensions.

Technical FAQs

What type of motor applications are suitable for the ATV930C25N4?

The ATV930C25N4 is intended for industrial variable-speed motor applications where motor speed and torque need to be controlled according to process requirements. Typical applications include pumps, fans, compressors, conveyors, and other large motor-driven equipment.

Why use an ATV930C25N4 instead of operating a motor at fixed speed?

Variable-speed control allows the motor to operate closer to the actual process demand. In applications such as pumping and ventilation, this can improve process regulation and avoid running the motor continuously at a higher speed than necessary.

How does the ATV930C25N4 communicate with a PLC or DCS?

The drive can be incorporated into an automation architecture where the control system sends operating commands and receives drive status, alarms, and process-related information. The exact communication arrangement depends on the selected control architecture and installed communication interfaces.

What should be considered when installing a 203 kg ATV930C25N4 drive?

The installation must account for mechanical support, lifting and positioning, electrical connections, heat dissipation, ventilation, grounding, cable routing, and maintenance access. The substantial drive weight should be considered during cabinet and equipment-room planning.
