Product Details

ATV310HU15N4 Product Description

The Schneider Electric ATV310HU15N4 is a 1.5 kW / 400 V three-phase variable frequency drive from the Altivar 310 series, engineered for seamless integration into layered industrial control architectures. Designed to deliver consistent motor speed regulation, energy efficiency, and reliable signal management, the ATV310HU15N4 occupies a critical position within the execution layer of any modern automation platform. Its compact DIN-rail or panel-mount form factor, combined with native compatibility with Schneider's broader Modicon and Altivar ecosystem, makes it a preferred choice for system integrators and OEM panel builders who demand both performance and long-term maintainability.

In a fully realised automation architecture, the ATV310HU15N4 does not operate in isolation. It functions as a coordinated execution node within a multi-layer control hierarchy that spans the control layer, I/O layer, communication layer, power layer, HMI layer, protection layer, and maintenance layer. Understanding how this drive interacts with each of these layers is essential for engineers designing scalable, redundancy-capable, and diagnostics-ready systems.

At the control layer, the ATV310HU15N4 receives speed references and run/stop commands from a Modicon M221 or M241 programmable logic controller via hardwired digital I/O or Modbus RTU serial communication. The drive's integrated Modbus RTU port enables direct parameter read/write from the PLC, allowing dynamic speed adjustment, fault acknowledgement, and drive status monitoring without additional communication gateways. For more complex architectures requiring CANopen or EtherNet/IP connectivity, the ATV310 series supports optional communication cards, enabling integration into Schneider's EcoStruxure Machine architecture alongside Modicon M340 or M580 CPUs.

At the I/O layer, the ATV310HU15N4 provides two analogue inputs (0–10 V / 4–20 mA), four digital inputs, one analogue output, and one relay output. These I/O points interface directly with field instruments, proximity sensors, and process transmitters, reducing the need for intermediate signal conditioning modules. When paired with Schneider TM3 expansion I/O modules or Advantys STB distributed I/O islands, the drive's I/O capacity can be extended to accommodate complex multi-axis or multi-zone process control requirements.

At the communication layer, Modbus RTU over RS-485 is the native protocol, supporting multi-drop topologies with up to 31 nodes on a single segment. This allows the ATV310HU15N4 to share a communication bus with other Altivar drives, Zelio Logic smart relays, and Magelis HMI terminals, creating a unified diagnostic and control network without additional hardware. For plants migrating toward Ethernet-based architectures, the optional VW3A3608 EtherNet/IP card enables the drive to participate in EtherNet/IP scanner-adapter topologies alongside Modicon M340 or Premium PLCs.

At the power layer, the ATV310HU15N4 operates on a 380–460 V AC, 50/60 Hz three-phase supply and delivers a rated output current of 4.1 A at 1.5 kW. The drive incorporates an integrated EMC filter (class C2) and a braking transistor, reducing the need for external EMC suppression components and simplifying cabinet wiring. When deployed alongside Schneider Acti9 iC60 circuit breakers and Tesys D contactors, the power distribution and motor protection architecture achieves a fully coordinated Type 2 coordination rating, ensuring both personnel safety and equipment protection under fault conditions.

At the HMI layer, the ATV310HU15N4 is compatible with the Magelis GTO and STO series touchscreen terminals via Modbus RTU, enabling operators to monitor drive speed, current, voltage, and fault history in real time. Parameter configuration can also be performed using the SoMove PC software tool over a USB-to-RJ45 programming cable, allowing engineers to clone drive configurations across multiple units during commissioning — a significant time-saving advantage in large-scale panel builds involving multiple ATV310 drives.

At the protection layer, the drive incorporates motor thermal protection (I²t), overcurrent protection, overvoltage and undervoltage detection, phase loss detection, and short-circuit protection. These built-in protection functions reduce reliance on external motor protection relays such as the Tesys T motor management relay for standard applications, while still allowing coordination with upstream Compact NSX moulded case circuit breakers for full system-level protection coordination.

At the maintenance layer, the ATV310HU15N4's Modbus RTU interface enables remote fault diagnostics, parameter backup, and predictive maintenance data collection without physical access to the drive. Fault codes, run hours, and thermal state data can be logged by the Modicon PLC and forwarded to a SCADA system such as Vijeo Citect or Wonderware InTouch for trend analysis and planned maintenance scheduling. This capability is particularly valuable in remote or hazardous installations where minimising on-site maintenance visits is a priority.

All units supplied by NANKMOS are sourced from authorised distribution channels, subjected to pre-shipment functional testing, and covered by a 12-Month Warranty against manufacturing defects. In-stock availability supports rapid deployment for both planned projects and emergency replacement scenarios, with global shipping to support international engineering and EPC contractors.

The ATV310HU15N4 achieves its full performance potential when deployed as part of a coordinated Schneider Electric automation platform. In a typical machine control cabinet, the drive operates alongside a Modicon M221 or M241 PLC as the primary controller, with a TM3DI16 digital input expansion module and TM3AQ4 analogue output module extending the I/O capacity for multi-axis process control. A Magelis STO511 or GTO5310 HMI terminal provides the operator interface, connected to the PLC via Ethernet and to the drive via Modbus RTU for real-time speed and fault visualisation.

Power distribution within the cabinet is managed by Acti9 iC60N miniature circuit breakers for branch circuit protection and Tesys D LC1D09 contactors for motor isolation. An ABL8REM24030 regulated 24 V DC power supply provides stable auxiliary power to the PLC, I/O modules, and HMI. For applications requiring motor braking, an external VW3A7004 braking resistor can be connected to the drive's integrated braking transistor, enabling controlled deceleration in high-inertia load applications such as centrifuges or conveyor systems.

In distributed architectures, the ATV310HU15N4 can be integrated into an Advantys STB distributed I/O island via a Modbus RTU gateway module, allowing the drive to be controlled from a remote Modicon M340 or M580 CPU over a PROFIBUS DP or EtherNet/IP backbone. This configuration is particularly effective in large process plants where drives are physically distributed across multiple motor control centres (MCCs) and centralised control is required from a single SCADA node.

The ATV310HU15N4 is deployed across a broad range of industrial sectors where precise motor speed control, energy efficiency, and system integration are critical requirements.

In manufacturing and packaging lines, the drive controls conveyor belt speeds, filling machine pump rates, and labelling station indexing motors, coordinated by a Modicon M241 PLC and supervised via a Magelis HMI. In water and wastewater treatment facilities, the ATV310HU15N4 regulates submersible pump and blower motor speeds in response to 4–20 mA level transmitter signals, enabling energy-efficient variable-flow operation and reducing mechanical wear compared to fixed-speed DOL starters.

In HVAC and building automation applications, the drive manages fan and pump motor speeds in air handling units and chiller systems, integrated into a BACnet or Modbus-based building management system (BMS). In petrochemical and process industries, the ATV310HU15N4 controls agitator, mixer, and compressor motors in hazardous area panel rooms, with the drive installed in IP54-rated enclosures and coordinated with Tesys T motor management relays for comprehensive motor protection and diagnostics.

In mining and materials handling applications, the drive provides soft-start and variable-speed control for conveyor drives and crusher feed motors, reducing mechanical shock loads and extending drivetrain service life. In shipbuilding and marine applications, the ATV310HU15N4 is used in auxiliary machinery control panels for ballast pump, ventilation fan, and winch motor control, where compact form factor and robust EMC performance are essential in electrically noisy shipboard environments.

Q1: Is the ATV310HU15N4 compatible with Modicon M221 and M241 PLCs for direct Modbus RTU control, and what cable and parameter settings are required? Yes. The ATV310HU15N4 communicates natively with Modicon M221 and M241 PLCs via Modbus RTU over RS-485 using a standard RJ45-to-terminal block cable. In the drive, set the communication address (parameter Add), baud rate (tbr, typically 19200 bps), and parity (tFo) to match the PLC serial port configuration. In SoMachine Basic or EcoStruxure Machine Expert, configure the PLC serial port as Modbus RTU master and map the drive's control word (register 8501h) and speed reference (register 8502h) to PLC output variables. Pre-shipment testing at NANKMOS verifies communication port integrity, and the 12-Month Warranty covers all hardware defects identified during commissioning.

Q2: Can multiple ATV310HU15N4 drives be networked on a single Modbus RTU bus, and what are the practical limits for system architects? Yes. Up to 31 ATV310HU15N4 drives can be addressed on a single RS-485 Modbus RTU segment using unique node addresses (1–247). For reliable communication in electrically noisy industrial environments, use shielded twisted-pair cable (Belden 9841 or equivalent), terminate the bus at both ends with 120 Ω resistors, and limit segment length to 1000 m at 19200 bps. For larger networks, a Modbus RTU-to-EtherNet/IP gateway such as the ATV-IMC or a third-party ProSoft MVI56E-MNET module can bridge multiple RS-485 segments to a single EtherNet/IP scanner, enabling centralised SCADA monitoring of all drives from a Modicon M580 CPU.
