Schneider Electric Altivar ATV340 Series Technical Notes

The Schneider Electric Altivar ATV340 series is a line of variable speed drives (VSDs) engineered for high-demand industrial applications including process automation, pump and fan control, compressor management, and conveyor systems. Deployed extensively across petrochemical refineries, water treatment facilities, offshore platforms, and continuous-process manufacturing plants, the ATV340 occupies a critical position in the global installed base of IEC-compliant motor control infrastructure. Its architecture supports both standalone drive operation and deep integration into distributed control systems (DCS) and programmable logic controller (PLC) networks via industrial fieldbus protocols including EtherNet/IP, Modbus TCP, PROFIBUS DP, CANopen, and DeviceNet.

The ATV340 series covers a power range from 0.37 kW to 75 kW (400 V three-phase), with dedicated variants for 200 V and 600 V supply networks. Its IP21/IP55 enclosure options and integrated EMC filters make it suitable for both panel-mount and standalone cabinet installations in harsh industrial environments.

The Evolution of ATV340 Architecture

The ATV340 is the direct successor to the Altivar 312 and Altivar 320 platforms, consolidating their feature sets while introducing a unified commissioning interface via the SoMove software suite and the Altivar Process ATV600/ATV900 ecosystem compatibility layer. Early Altivar drives (ATV11, ATV18, ATV28) used proprietary serial communication and analog I/O-only control. The ATV312 introduced CANopen and Modbus RTU as standard. The ATV320 added EtherNet/IP and PROFIBUS DP options via plug-in communication cards.

The ATV340 retains backward-compatible parameter structures with the ATV320, reducing re-engineering time during panel upgrades. Its dual-port EtherNet/IP interface supports Device Level Ring (DLR) topology — a key requirement for high-availability process lines. The integrated safety function STO (Safe Torque Off) to SIL 2 / PLd eliminates the need for external safety relays in most machine safety architectures.

ATV340 Full Catalog & Functionalities (SKU List)

The following SKUs represent the verified production range of the Altivar ATV340 series, classified by power rating and supply voltage. Each entry reflects a distinct catalog reference with defined power, current, and enclosure specifications.

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Sourcing Hard-to-Find & Obsolete ATV340 Parts

For obsolete communication cards (VW3A3601 through VW3A3609) and keypad accessories (VW3A1101, VW3A1102), DriveKNMS maintains separate inventory pools with individual test certification.

Quality Control for the ATV340 Range

Each ATV340 unit processed through DriveKNMS undergoes a structured inspection and functional test protocol designed around the drive's internal architecture:

• Power stage verification: IGBT gate drive integrity test, DC bus capacitance measurement, and inrush current characterization
• RFQ terms review: Commercial terms are confirmed during RFQ review based on model, condition, documentation, quantity and destination.
• Fieldbus communication test: Live Modbus TCP and EtherNet/IP polling via test PLC to confirm register map integrity
• STO function validation: Safe Torque Off channel activation test per IEC 62061 SIL 2 verification procedure
• Enclosure inspection: IP rating integrity check, terminal block torque verification, and EMC filter continuity

All test results are documented and supplied with each unit shipment. Reconditioned units include a before/after parameter comparison report.
