Product Overview
The Schneider VW3A3307 is an Altivar PROFIBUS DP Communication Card used to connect compatible Altivar variable speed drives to a PROFIBUS DP industrial network. It adds fieldbus communication capability to the drive, allowing control commands, operating data, status information, and drive parameters to be exchanged with a PLC or other PROFIBUS DP master.
In a typical automation cabinet, the VW3A3307 is installed in the communication interface of the compatible Altivar drive. The drive continues to handle motor control locally, while the PROFIBUS connection gives the plant controller access to the drive through the network.
This arrangement is particularly useful when several drives are installed on the same production line. Instead of wiring individual run commands and feedback signals to every drive, the controller can exchange the required information through the PROFIBUS DP network. Drive status and diagnostic information can also be made available to the supervisory control system.

Product Features
- PROFIBUS DP connectivity — Adds PROFIBUS DP communication capability to compatible Altivar drives.
- Drive-to-PLC communication — Allows the automation controller to exchange commands and operating information with the drive.
- Centralized drive management — Multiple compatible drives can be integrated into the same fieldbus control architecture.
- Parameter access — Supports network-based access to drive operating information and configurable parameters where supported by the drive.
- Status and diagnostic exchange — Drive operating states and diagnostic information can be communicated to the control system.
- Compact communication interface — Integrates into the Altivar drive rather than requiring a separate external communication gateway.
Working Principle
The VW3A3307 acts as the communication interface between the internal control system of the Altivar drive and a PROFIBUS DP network.
A PLC or other PROFIBUS DP master sends process commands through the network. The communication card passes these commands to the drive control electronics, which then handles the actual motor operation. Depending on the drive configuration, the controller can issue commands such as start/stop and speed references while receiving status and operating information from the drive.
For a production line with several motors, the same PROFIBUS network can be used to coordinate individual Altivar drives. The PLC can monitor whether each drive is running, stopped, faulted, or ready and can react accordingly in the control program.
The communication card therefore does not replace the drive’s motor-control functions. It provides the data path that allows those functions to be managed from the plant automation network.
Role in an Altivar PROFIBUS DP System
| System Element | Function |
|---|---|
| PLC / PROFIBUS DP Master | Executes the automation program and exchanges commands with the drives |
| VW3A3307 Communication Card | Provides the PROFIBUS DP interface for the compatible Altivar drive |
| Altivar Variable Speed Drive | Controls motor speed, torque, acceleration, and related drive functions |
| PROFIBUS DP Network | Carries cyclic control and status data between the controller and drives |
| AC Motor | Executes the mechanical motion commanded by the drive |
| HMI / SCADA System | Displays drive operating conditions and selected diagnostic information |
Industrial Applications
| Application | Typical Use |
|---|---|
| Conveyor Systems | Network-based speed and start/stop control of multiple conveyor motors |
| Packaging Machinery | Coordinating several variable speed drives from a central PLC |
| Material Handling | Controlling motors for conveyors, feeders, lifts, and transfer equipment |
| Pumping Systems | Integrating pump drives into a centralized process-control network |
| Fans and Blowers | Providing PLC access to motor speed commands and operating status |
| Production Lines | Connecting multiple Altivar drives to a common PROFIBUS DP control architecture |
| Machine Automation | Reducing hardwired control connections for distributed motor drives |
Installation and Maintenance
- Verify drive compatibility — Confirm that the target Altivar drive supports the VW3A3307 communication card before installation.
- Disconnect power before installation — Remove power from the drive and follow the applicable electrical safety procedures before accessing the communication-card installation area.
- Install the card correctly — Seat the communication card securely in the designated drive interface and ensure that the mechanical connection is fully engaged.
- Configure the PROFIBUS network — Set the required communication parameters and station address according to the network architecture and drive configuration.
- Check PLC configuration — The PROFIBUS master configuration should correspond to the installed drive and communication setup.
- Inspect network wiring — During maintenance, check PROFIBUS connectors, cable routing, shielding, and termination where applicable.
- Review diagnostic information — If the PLC cannot communicate with the drive, check the card installation, station address, network wiring, drive communication settings, and controller configuration before replacing hardware.

Technical FAQs
What type of information can the VW3A3307 exchange with a PROFIBUS DP controller?
The communication link can be used for drive control commands, operating status, process-related values, and parameter information supported by the particular Altivar drive and its configured communication profile.
Does installing the VW3A3307 make the Altivar drive dependent on PROFIBUS for local motor control?
No. The drive retains its own motor-control functions. The communication card provides an additional control and data interface, allowing a PROFIBUS DP master to interact with the drive as part of the automation system.
What should be checked if the PLC detects the network but cannot control the drive?
Check the PROFIBUS station address, master configuration, drive communication settings, control-command source, reference source, and the communication card installation. A network connection alone does not guarantee that the drive has been configured to accept commands through PROFIBUS.
Can the VW3A3307 be used to connect several Altivar drives to one PLC?
A PROFIBUS DP network can contain multiple drive nodes, provided the drives and communication interfaces are compatible with the network architecture. Each node must be correctly addressed and configured in the PROFIBUS master.
