Product Overview
The Schneider VW3A3327 is an Altivar PROFINET Communication Card used to integrate compatible Altivar variable speed drives into a PROFINET industrial Ethernet network. It gives the drive a direct communication interface for exchanging control commands, speed references, operating status, and available diagnostic information with a PROFINET controller.
In a machine with several variable speed drives, the VW3A3327 can be used to bring individual drives into a common automation network. The PLC handles the overall sequence and coordination, while each Altivar drive continues to perform the actual motor-control task.
This configuration is useful when the control system needs more than basic start/stop wiring. For example, a PLC can issue a speed reference to a conveyor drive, monitor its operating state, and respond to a drive fault through the same PROFINET network. The result is a cleaner connection between the motion-control layer and the plant automation system.

Product Features
- PROFINET connectivity — Connects compatible Altivar drives to a PROFINET industrial Ethernet network.
- Controller-to-drive communication — Supports exchange of drive commands, references, status information, and supported diagnostic data.
- Centralized drive control — Allows multiple networked drives to be managed from a common automation controller.
- Ethernet-based architecture — Fits automation systems where PROFINET is already used for PLC and field-device communication.
- Reduced hardwired I/O — Network communication can reduce the number of individual control and feedback wires required between the PLC and drive.
- Compact communication interface — Adds network capability within the Altivar drive architecture.
Working Principle
The VW3A3327 provides the communication path between the Altivar drive’s internal control functions and the PROFINET network.
A PROFINET controller, typically a PLC, exchanges configured process data with the drive. Depending on the drive configuration, this can include control commands, speed references, operating status, actual values, and diagnostic information. The communication card transfers the network data to and from the drive’s internal control system.
The motor itself remains under the control of the Altivar drive. The VW3A3327 does not replace the drive’s inverter or motor-control electronics; it allows those functions to be coordinated from the higher-level automation system.
In a conveyor application, for example, the PLC can send a running command and speed reference through PROFINET. The drive executes the motor-control task and returns operating information to the PLC, allowing the controller to coordinate the conveyor with sensors, upstream equipment, and downstream machines.
Role in an Altivar PROFINET System

Industrial Applications
| Application | Typical Use |
|---|---|
| Conveyor Systems | Coordinating conveyor speed and operating status through a PLC |
| Packaging Machinery | Synchronizing multiple drives with other machine-control devices |
| Material Handling | Controlling motors for conveyors, feeders, transfer systems, and lifting equipment |
| Pumping Equipment | Integrating variable speed pumps into a PROFINET-based control system |

| Process Machinery | Connecting motor drives with PLC and HMI systems using industrial Ethernet |
| Automated Production Lines | Managing multiple Altivar drives as part of a centralized PROFINET architecture |
Installation and Maintenance
- Confirm Altivar compatibility — Verify that the target drive supports the VW3A3327 before installation.
- Isolate the drive from power — Follow the applicable electrical safety procedures before installing or removing the communication card.
- Install the card securely — Ensure that the communication card is correctly seated in the designated interface and mechanically secured.
- Configure the PROFINET device — Assign the required network identification and configure the drive correctly in the PROFINET controller.
- Check the command source — If network commands do not operate the drive, verify that the drive is configured to receive its command and reference through the intended communication channel.
- Inspect Ethernet connections — Check connectors, network cables, shielding, and physical routing during scheduled maintenance.
- Use diagnostics during troubleshooting — When communication is lost, check the PROFINET configuration, network connection, card installation, and drive parameters before replacing the hardware.

Technical FAQs
What does the VW3A3327 add to a compatible Altivar drive?
It adds a PROFINET communication interface, allowing the drive to exchange supported control, reference, status, and diagnostic data with a PROFINET controller.
How does PROFINET control differ from local drive control?
With PROFINET control, commands and references can originate from the automation controller and travel through the network to the drive. The Altivar drive still performs the actual inverter and motor-control functions according to its configuration.
Why might a PROFINET-connected drive show as available but still fail to respond to PLC commands?
A healthy network connection does not necessarily mean the drive is configured for network control. The command source, reference source, drive parameters, PROFINET device configuration, and PLC program should all be checked.
Is the VW3A3327 suitable for a system containing several Altivar drives?
It can be used as part of a multi-drive PROFINET architecture when the individual Altivar drives are compatible with the card. Each drive must be correctly identified and configured within the PROFINET controller, with its corresponding process data and control settings.
