Proven Application Environments
- Pump & Fan Control: Energy-saving speed regulation for centrifugal pumps, cooling fans, and HVAC air-handling units with PID closed-loop feedback.
- Conveyor & Material Handling: Smooth start/stop and precise speed control for belt conveyors, roller tables, and packaging lines.
- Compressor Drives: Constant-torque load management for screw and reciprocating compressors in industrial utilities.
- Mixer & Agitator: Variable torque profiles for chemical processing, food & beverage mixing, and water treatment agitators.
- OEM Machine Integration: Panel-mount installation in textile, printing, woodworking, and plastics machinery with EtherNet/IP or PROFINET fieldbus.
- Retrofit Projects: Direct replacement for legacy ATV31 / ATV312 / ATV61 drives in existing control panels with compatible wiring footprint.
Engineering Advantages
- Sensorless Vector Control (SVC): Delivers high starting torque (200% at 0.5 Hz) without encoder feedback, reducing installation complexity.
- Integrated EMC Filter: Class C2 filter eliminates the need for external EMC components, saving panel space and BOM cost.
- Embedded Modbus RTU: Native RS-485 Modbus RTU via RJ45 enables direct integration with Schneider M221/M241/M251 PLCs and third-party SCADA systems without additional gateways.
- Plug-in Fieldbus Cards: Modular communication expansion (CANopen, EtherNet/IP, PROFIBUS DP, PROFINET) future-proofs the drive for evolving network architectures.
- Energy Savings Mode: Automatic flux optimization reduces motor iron losses during partial-load operation, achieving up to 30% energy savings vs. DOL starters.
- Compact DIN-Rail Compatible Footprint: Optimized for space-constrained control panels; side-by-side mounting with zero clearance (with derating).
- EcoStruxure Ready: Fully compatible with Schneider Electric’s EcoStruxure Machine and Plant architectures for IIoT-enabled predictive maintenance.
System Architecture & Signal Flow
The ATV340D15N4 operates within a standard three-tier automation hierarchy:
- Level 1 – Field: Three-phase motor (induction or PM) connected to drive output terminals U/V/W. Encoder feedback optional via HTL/TTL input card.
- Level 2 – Control: Drive receives speed reference via analog input (AI1: 0–10V or 4–20mA) or digital preset speeds via DI terminals. Local/Remote switching via DI6.
- Level 3 – Supervision: Modbus RTU (RJ45) or optional fieldbus card connects to PLC (e.g., Schneider M241, Siemens S7-1200) or SCADA for parameter read/write, fault monitoring, and energy metering.
Typical wiring sequence: L1/L2/L3 (supply) → Internal EMC filter → Rectifier → DC bus → IGBT inverter → U/V/W (motor). Dynamic braking resistor connects to PA/PB terminals for high-inertia load deceleration.

Technical FAQ
Q: Is the ATV340D15N4 compatible with permanent magnet (PM) motors?
A: Yes. The ATV340 supports both standard induction motors and permanent magnet synchronous motors (PMSM) in open-loop SVC mode.
Q: Can I use this drive with a Siemens S7-1200 PLC via PROFINET?
A: Yes, with the optional VW3A3627 PROFINET communication card installed. The drive appears as a standard PROFINET IO device.
Q: What is the difference between ATV340D15N4 and ATV340D15N4E?
A: The ATV340D15N4E variant includes an enhanced EMC filter (Class C1) and conformal coating for harsh environments. The standard D15N4 is suitable for industrial environments meeting Class C2 requirements.
Q: Does the drive support Safe Torque Off (STO)?
A: Yes. The ATV340 series includes integrated STO (SIL 2 / PLd) via dedicated STO terminals, eliminating the need for external safety contactors in most applications.
Q: What is the minimum motor cable length recommendation?
A: Schneider recommends shielded motor cable (e.g., LIYCY) with maximum length of 50 m without output filter, or up to 100 m with optional dV/dt filter (VW3A4721).
