Schneider Electric ATV340D11N4 Variable Frequency Drive

Product Details

ATV340D11N4 Product Description

The Schneider Electric ATV340D11N4 is engineered as a system-matched drive component within the Altivar 340 series, designed to operate cohesively across the full automation stack rather than as a standalone inverter. In a complete Schneider Electric control architecture, the ATV340D11N4 occupies the drive layer, receiving speed and torque commands from the control layer while feeding real-time motor status back to supervisory systems — enabling closed-loop process optimization across the entire plant floor.

At the control layer, the ATV340D11N4 integrates directly with Modicon M340 and Modicon M580 PLCs via Modbus RTU or optional EtherNet/IP communication cards, allowing deterministic command exchange and parameter monitoring without additional protocol converters. For applications requiring PROFINET or PROFIBUS DP connectivity, the VW3A3607 and VW3A3608 communication option cards extend the drive's fieldbus reach, ensuring compatibility with third-party control platforms and mixed-vendor architectures.

At the I/O layer, the ATV340D11N4 provides onboard analog and digital I/O terminals that interface with Modicon TM3 distributed I/O modules, enabling local signal conditioning and remote I/O expansion without burdening the main CPU. This architecture supports modular deployment across large control cabinets where I/O density and signal integrity are critical. Signal isolation between the drive's power stage and the control wiring is maintained through the drive's internal EMC filtering, reducing interference on adjacent Modicon TM5 or TM7 I/O segments.

At the power layer, the ATV340D11N4 is typically paired with Schneider Electric Acti9 or Compact NSX circuit breakers for upstream protection, and ABL8 series regulated power supplies for control circuit stability. Proper coordination between the drive's internal braking resistor terminals and external VW3A7 series braking resistors ensures safe deceleration in high-inertia applications such as centrifugal pumps, fans, and conveyor systems.

At the HMI layer, the ATV340D11N4 supports direct integration with Harmony HMIG and Magelis GTU operator panels via Modbus serial or Ethernet, providing operators with real-time drive status, fault history, and parameter adjustment without requiring engineering workstation access. This reduces commissioning time and supports on-site maintenance by non-specialist personnel.

At the communication layer, the drive's optional VW3A3720 EtherNet/IP card enables seamless integration into Schneider Electric's EcoStruxure Plant architecture, where drive data — including energy consumption, motor temperature estimates, and fault logs — is aggregated at the SCADA or MES level for predictive maintenance and energy management. This positions the ATV340D11N4 not merely as a motor controller but as an intelligent node within a connected industrial ecosystem.

For redundancy-critical applications, the ATV340D11N4 supports bypass contactor schemes using TeSys D or TeSys K contactors, allowing automatic or manual transfer to direct-on-line motor starting in the event of drive fault — a requirement in water treatment, HVAC, and process industries where motor availability is non-negotiable. The drive's built-in PID controller further reduces dependency on external loop controllers for simple single-loop applications, freeing PLC resources for higher-level logic.

Long-term maintenance efficiency is supported by the ATV340D11N4's onboard diagnostics, including fault history logging, real-time thermal monitoring, and parameter backup via the VW3A1101 remote keypad or SoMove PC software. These tools allow maintenance engineers to perform drive health assessments, parameter cloning across multiple drives, and firmware updates without removing the unit from service — reducing planned downtime and extending mean time between failures across the drive population.

The ATV340D11N4 is deployed across a broad range of industrial sectors where precise motor speed control, energy efficiency, and system integration are primary engineering requirements.

Manufacturing & Assembly Lines: In automotive and general manufacturing, the ATV340D11N4 controls conveyor drives, rotary indexing tables, and servo-adjacent positioning axes where smooth acceleration profiles and torque repeatability are essential. Its sensorless flux vector control mode delivers high starting torque without encoder feedback, reducing mechanical complexity and installation cost.

Water & Wastewater Treatment: Pump and blower applications in municipal water treatment plants benefit from the drive's built-in PID control and sleep/wake functions, which optimize energy consumption during low-demand periods. The drive's IP55 variant supports installation in humid or wash-down environments without additional enclosure upgrades.

Power & Energy: In power generation auxiliaries and substation cooling systems, the ATV340D11N4 provides reliable fan and pump control with full fieldbus integration into substation automation systems. Its wide supply voltage tolerance (380–480 V ±10%) accommodates grid voltage fluctuations common in industrial power environments.

Oil, Gas & Petrochemical: For compressor and pump skid applications, the drive's robust EMC filtering and optional conformal coating support operation in electrically noisy environments. Integration with safety PLCs via hardwired STO (Safe Torque Off) inputs meets SIL 2 / PLd functional safety requirements without external safety relays in many configurations.

Mining & Metallurgy: Conveyor, crusher feed, and ventilation fan drives in mining operations demand high reliability and tolerance for voltage sags. The ATV340D11N4's undervoltage ride-through and automatic restart functions minimize production interruptions during transient grid disturbances.

Packaging & Material Handling: High-cycle packaging lines require drives with fast dynamic response and precise speed regulation. The ATV340D11N4's flux vector control and configurable ramp profiles support multi-axis coordination when networked with Modicon PLCs, enabling synchronized motion across multiple drive axes without a dedicated motion controller.

Q1: Is the ATV340D11N4 compatible with Modicon M580 PLCs and EcoStruxure architecture? Yes. The ATV340D11N4 supports native Modbus RTU communication onboard and can be extended with optional EtherNet/IP (VW3A3720) or PROFINET (VW3A3627) communication cards for direct integration with Modicon M580 CPUs and EcoStruxure Plant SCADA systems. Device DTM files are available in SoMove and EcoStruxure Control Expert for seamless engineering configuration. The drive appears as a standard fieldbus node, supporting full parameter read/write and real-time status monitoring from the PLC program.

Q2: What installation and commissioning considerations apply when deploying the ATV340D11N4 in a multi-drive control cabinet? For multi-drive cabinet installations, maintain minimum clearances per the ATV340 installation guide (typically 50 mm lateral, 100 mm top/bottom for IP21 units). Use shielded motor cables with grounded shields at both ends to minimize EMC interference on adjacent I/O wiring. Coordinate upstream circuit breaker ratings with the drive's input current specifications (approximately 25 A at 11 kW/400 V). For shared DC bus or common braking resistor configurations, consult Schneider Electric's application note AN-ATV340-DCbus. SoMove software supports parameter upload/download and fault log extraction during commissioning without interrupting drive operation.

Q3: What does the 12-Month Warranty cover, and how is long-term spare parts availability managed? The ATV340D11N4 is supplied with a 12-Month Warranty covering manufacturing defects in materials and workmanship from the date of shipment. Warranty service includes repair or replacement at the supplier's discretion, with advance replacement available for critical applications subject to prior arrangement. For long-term maintenance planning, Schneider Electric supports the Altivar 340 series with a minimum 10-year spare parts availability commitment, including control boards, power modules, and fan assemblies. Recommended spare parts for high-availability installations include the internal cooling fan assembly and the control board, both of which are field-replaceable without specialized tooling. Stock availability and lead times are confirmed at the time of order.
