VFD for Compressors: Selection Guide
How to select and size a VFD for screw, reciprocating and centrifugal compressors, covering overload rating, turndown limits and energy savings.
The Schneider Electric VW3A3601 is a communication module that adds EtherCAT fieldbus connectivity to Altivar 32, Altivar Machine ATV320/ATV340, Altivar Process ATV900, Altivar Process Modular and Lexium 32 drives. It transmits at 100 Mbps over two RJ45 connectors and supports CANopen over EtherCAT (CoE) with the CiA 402 velocity drive profile.
Choose the VW3A3601 for EtherCAT fieldbus segments where sub-millisecond cyclic updates matter, since EtherCAT's daisy-chained 100 Mbps ring outperforms Modbus TCP or CANopen for coordinated multi-axis motion. The module's CiA 402 velocity profile lets the drive slot directly into a standard EtherCAT motion controller without a custom mapping layer.
