Schneider Electric ATV340 Series Technical Notes

The Schneider Electric Altivar ATV340 series represents the current-generation compact variable frequency drive (VFD) platform engineered for demanding industrial applications including chemical processing plants, water treatment facilities, material handling systems, and heavy manufacturing lines. Deployed across six continents, the ATV340 range has established a significant installed base in sectors where motor control precision, harmonic compliance, and functional safety integration are non-negotiable procurement criteria.

The ATV340 series covers a power range from 0.37 kW to 75 kW (three-phase 380–480 V), with dedicated variants for single-phase input and high-power cabinet integration. Its architecture is built around an embedded Ethernet/IP and Modbus TCP communication stack, STO (Safe Torque Off) SIL 2 / PLd safety function, and a graphical keypad interface — all standard, without optional cards required for basic commissioning.

The Evolution of ATV340 Architecture

The ATV340 is the direct successor to the Altivar 312 and Altivar 320 platforms. The ATV312 (discontinued, circa 2018) served as the workhorse compact drive for simple pump and fan applications but lacked embedded Ethernet and advanced safety functions. The ATV320 bridged the gap with improved EMC filtering and fieldbus flexibility but retained a separate safety option card requirement.

The ATV340 consolidates these capabilities into a single hardware generation: embedded dual-port Ethernet switch (for line topology without additional switches), STO wired directly to the control board, and a unified firmware architecture shared with the ATV340 cabinet drives. This means engineering teams migrating from ATV312 or ATV320 installations face a well-documented parameter migration path, though physical mounting footprints differ and must be verified against existing panel layouts.

Compatibility note: ATV340 drives are not backward-compatible with ATV312 accessories (filters, chokes, braking resistors) at the part-number level. Procurement teams should treat each generation as a distinct BOM line item and verify accessory cross-references via Schneider's Product Lifecycle Management (PLM) database before issuing RFQs.

Quality Control for the ATV340 Range

DriveKNMS applies the following test protocol to all ATV340 units prior to shipment:

• Visual inspection: PCB for corrosion, burn marks, swollen capacitors, and connector pin integrity
• Power-on self-test: Firmware boot verification, keypad display function, and fault code readout
• No-load run test: Output voltage symmetry across U/V/W at 10 Hz, 30 Hz, and 50 Hz
• STO function test: Verification of Safe Torque Off response per IEC 62061 test procedure
• Communication test: Ethernet/IP and Modbus TCP ping and register read/write cycle
• Insulation resistance test: 500 V DC megger test on power terminals prior to packaging
