Schneider Electric ATV310HU55N4 Variable Frequency Drive

Product Details

ATV310HU55N4 Product Description

The Schneider Electric ATV310HU55N4 is a 5.5 kW three-phase variable frequency drive from the Altivar 310 series, engineered to deliver precise motor speed control, measurable energy savings, and reliable load management across demanding industrial production environments. Designed for integration into smart factory architectures, this drive reduces unnecessary motor energy consumption by matching output frequency and voltage to actual load demand — eliminating the fixed-speed energy waste that accounts for a significant share of industrial electricity costs. With a compact DIN-rail-compatible footprint, built-in EMC filter, and a robust thermal management design, the ATV310HU55N4 is a proven energy-control component for continuous-duty production lines where uptime, efficiency, and predictable operating costs are non-negotiable.

In a well-designed energy-aware production cell, the ATV310HU55N4 operates as the central motor-control node, receiving speed references from a Schneider Modicon M221 or M241 PLC via Modbus RTU. The PLC aggregates process data from upstream sensors — flow meters, pressure transducers, and temperature probes — and dynamically adjusts the drive's output frequency to match real-time load demand. This closed-loop strategy eliminates the energy penalty of throttling valves or mechanical dampers, which are common in legacy fixed-speed installations.

For power quality monitoring, the ATV310HU55N4 pairs naturally with a Schneider PowerLogic PM5000 series power meter or an iEM3000 energy meter, both of which can be integrated on the same Modbus network to provide per-circuit kWh consumption data to a SCADA system such as Schneider EcoStruxure Plant. This combination enables real-time energy dashboards, demand-side management, and automated load-shedding routines during peak tariff windows.

On the I/O side, the drive's onboard digital and analog inputs interface directly with Schneider TM3 expansion I/O modules, allowing the control system to monitor drive status, fault codes, and thermal warnings without additional communication hardware. For HMI visualization, a Magelis GTU or HMIG3U panel connected to the Modicon PLC can display motor speed, current draw, energy consumption, and fault history on a single operator screen — reducing the diagnostic time required during shift changeovers.

Where CANopen is the preferred fieldbus, the ATV310HU55N4 supports native CANopen DS402 motion profiles, enabling coordinated multi-axis control alongside Lexium 32 servo drives in applications such as synchronized conveyor indexing or tension-controlled winding. This architecture keeps all drive and servo data on a single deterministic network, simplifying the SCADA integration layer and reducing wiring complexity. An Altivar ATV320 or ATV340 can serve as a higher-power companion drive on the same CANopen segment for mixed-load production lines.

Variable-speed motor control is the single highest-impact energy intervention available to most manufacturing facilities. In pump and fan applications — which represent the majority of ATV310HU55N4 deployments — the affinity laws dictate that a 20% reduction in motor speed produces a 49% reduction in power consumption. The ATV310HU55N4 exploits this relationship continuously, adjusting output to match process demand rather than running at full speed and throttling flow mechanically.

Beyond raw energy savings, the drive's soft-start and soft-stop capability eliminates the mechanical shock and inrush current spikes associated with direct-on-line motor starting. This directly reduces thermal stress on motor windings, bearing wear, and coupling fatigue — extending mean time between failures and reducing unplanned downtime. In a production line context, fewer unplanned stops translate directly to higher overall equipment effectiveness (OEE) and more stable production takt times.

The ATV310HU55N4's built-in motor thermal protection function continuously models winding temperature based on current draw and ambient conditions, triggering a controlled deceleration before a thermal fault occurs. This predictive thermal management approach prevents the abrupt motor trips that disrupt production schedules and require manual restart procedures. When integrated with a Schneider EcoStruxure Asset Advisor or equivalent condition-monitoring platform, the drive's operational data can feed predictive maintenance algorithms that flag bearing degradation or insulation deterioration weeks before a failure event.

For facilities operating under energy management standards such as ISO 50001, the ATV310HU55N4 provides the metered consumption data — accessible via Modbus registers — needed to populate energy performance indicators (EnPIs) and demonstrate continuous improvement. Combined with a PowerLogic energy meter and EcoStruxure Energy Hub, the drive becomes a measurable, auditable contributor to the facility's energy reduction targets. All units supplied by NANKMOS are pre-tested under load, verified against factory specifications, and shipped with a 12-month warranty covering parts and workmanship — ensuring that energy savings projections are not undermined by early-life component failures.

Q1: What energy savings can I realistically expect from the ATV310HU55N4 in a pump or fan application? In centrifugal pump and fan applications running at partial load for the majority of operating hours, energy savings of 30–50% versus direct-on-line operation are typical. Actual savings depend on the load profile, duty cycle, and the baseline control method being replaced. NANKMOS can provide application-specific guidance based on your motor nameplate data and operating schedule.

Q2: Is the ATV310HU55N4 compatible with my existing Modicon PLC and Modbus RTU network? Yes. The ATV310HU55N4 supports Modbus RTU as a standard embedded communication protocol, making it directly compatible with Schneider Modicon M221, M241, M251, and M262 PLCs without additional communication cards. CANopen is also supported natively. For PROFIBUS or PROFINET integration, an optional VW3A3608 or VW3A3627 communication card is required.

Q3: Can the ATV310HU55N4 replace an older Altivar 11, Altivar 21, or Altivar 31 drive of the same power rating? In most cases, yes. The Altivar 310 series was designed as a functional successor to the Altivar 31, sharing compatible terminal layouts and parameter structures that simplify retrofit projects. NANKMOS recommends a parameter backup of the existing drive before replacement and can advise on any wiring or configuration differences specific to your installation.

Q4: What does the 12-month warranty cover, and how does NANKMOS handle warranty claims? All ATV310HU55N4 units supplied by NANKMOS are individually tested under load prior to shipment and covered by a 12-month warranty against manufacturing defects and component failure under normal operating conditions. In the event of a warranty claim, NANKMOS provides a replacement unit or repair service with a target response time of 5 business days. Units are held in stock and can be dispatched immediately upon order confirmation, minimising production downtime during replacement.
