Schneider Electric ATV930C16N4C Variable Speed Drive

Product Details

ATV930C16N4C Product Description

The Schneider ATV930C16N4C is a high-performance variable speed drive engineered for seamless integration into modern industrial communication architectures. Designed to operate within the ATV930 series platform, this drive supports multi-protocol connectivity — including EtherNet/IP, Modbus RTU, Modbus TCP, and PROFIBUS DP — making it a critical node in smart factory data chains that span field devices, PLC controllers, SCADA systems, and cloud-based analytics platforms.

In today's connected manufacturing environment, the ATV930C16N4C does far more than regulate motor speed. It acts as an active participant in the plant-wide data network, continuously transmitting real-time operational parameters — including output frequency, motor current, torque reference, fault codes, and energy consumption — upstream to supervisory systems. This live data stream enables operators to monitor drive health, detect anomalies early, and respond to process deviations without dispatching field technicians.

The ATV930C16N4C is built to anchor the drive layer within a multi-tier industrial network. At the field level, sensors and encoders feed process signals directly into the drive's analog and digital I/O terminals. These signals are conditioned and processed locally, then transmitted via Modbus RTU over RS-485 to a remote I/O module — such as the Schneider TM3 expansion I/O series — which aggregates distributed field data before forwarding it to the control layer.

At the control layer, a Schneider Modicon M340 or M580 PLC receives drive status, speed reference, and fault registers via Modbus TCP over EtherNet/IP. The PLC executes closed-loop control logic and issues speed setpoints back to the ATV930C16N4C in real time, maintaining process stability across variable load conditions. Simultaneously, the drive's PROFIBUS DP interface allows integration with legacy fieldbus networks, enabling coexistence with older automation infrastructure without requiring a full system overhaul.

At the supervisory layer, a Schneider EcoStruxure SCADA Expert (ClearSCADA) or third-party SCADA platform connects via the plant Ethernet backbone. The ATV930C16N4C's EtherNet/IP port delivers cyclic process data — including running frequency, DC bus voltage, output current, and thermal state — directly to the SCADA historian. This data is visualized on Magelis GTU HMI panels installed at operator workstations, providing real-time dashboards and trend charts that support informed decision-making on the production floor.

For edge computing scenarios, an industrial edge gateway — such as the Schneider EcoStruxure Machine Advisor agent or a compatible third-party OPC-UA gateway — can be deployed between the drive network and the cloud analytics layer. The gateway normalizes Modbus and EtherNet/IP data into standardized formats, enabling upload to MES or ERP platforms for production reporting, energy benchmarking, and predictive maintenance scheduling. Paired with an industrial managed Ethernet switch (e.g., Schneider ConneXium or Hirschmann MACH series), the network segment hosting the ATV930C16N4C benefits from VLAN segmentation, port mirroring, and SNMP-based network health monitoring.

Power quality and supply stability are maintained by pairing the ATV930C16N4C with a Schneider Phaseo ABL8 industrial power supply, which provides regulated 24 VDC to the drive's control card and communication modules. In multi-drive installations, a Schneider ATV930 braking resistor module or line reactor is recommended to manage regenerative energy and protect upstream network components from harmonic disturbances.

Many industrial sites operate with fragmented automation architectures — legacy PLCs running proprietary protocols, drives isolated from the SCADA network, and I/O modules that cannot communicate upstream. The ATV930C16N4C directly addresses these integration challenges through its multi-protocol design.

Protocol Fragmentation: Sites running mixed Modbus RTU and EtherNet/IP environments no longer need dedicated protocol converters for every drive. The ATV930C16N4C natively bridges both protocols, reducing gateway hardware costs and simplifying network topology.

Data Islands: Drive operational data — energy consumption, fault history, run hours — is often trapped at the device level. With Modbus TCP and EtherNet/IP connectivity, the ATV930C16N4C pushes this data upstream to SCADA historians and MES platforms automatically, eliminating manual data collection and enabling continuous process optimization.

Remote Monitoring Gaps: Without network-connected drives, maintenance teams must physically inspect equipment to assess health. The ATV930C16N4C's remote diagnostics capability allows engineers to query fault logs, thermal status, and output parameters from any networked workstation or mobile HMI, reducing unplanned downtime and travel costs.

Production Line Transparency: By integrating the ATV930C16N4C into the plant SCADA/HMI layer, production managers gain real-time visibility into motor load, speed profiles, and energy draw across all connected drives — enabling line balancing, shift reporting, and OEE calculation without additional instrumentation.

Alarm Tracking and Escalation: The drive's built-in fault detection logic generates structured alarm messages that propagate through the Modbus or EtherNet/IP network to the SCADA alarm management system. Operators receive immediate notifications on HMI panels and, where configured, via email or SMS through the SCADA platform's alarm escalation module.

System Expansion: The ATV930C16N4C's standard communication interfaces ensure forward compatibility with future automation upgrades. Adding new drives, I/O modules, or edge gateways to the network requires no changes to the existing communication architecture — simply assign a new node address and configure the SCADA data map.

Q1: What is the communication latency of the ATV930C16N4C over EtherNet/IP?The ATV930C16N4C supports cyclic EtherNet/IP communication with configurable RPI (Requested Packet Interval) typically set between 10–100 ms depending on network load and PLC scan cycle. For most motor control and monitoring applications, a 20 ms RPI provides sufficient real-time responsiveness without overloading the network.

Q2: Is the ATV930C16N4C compatible with third-party SCADA and HMI systems?Yes. The drive's Modbus TCP and Modbus RTU interfaces are industry-standard protocols supported by virtually all major SCADA platforms — including Wonderware, Ignition, WinCC, and iFIX — as well as HMI panels from Siemens, Mitsubishi, and Proface. EtherNet/IP compatibility extends integration to Rockwell Automation ControlLogix and CompactLogix environments.

Q3: How does the ATV930C16N4C support remote diagnostics and predictive maintenance?The drive continuously logs operational parameters — including output frequency, motor current, thermal state, fault codes, and run hours — accessible via Modbus register map or EtherNet/IP explicit messaging. Maintenance teams can query this data remotely through SCADA or a dedicated asset management platform, enabling condition-based maintenance scheduling and early fault detection before unplanned shutdowns occur.

Q4: What warranty and pre-shipment testing does the ATV930C16N4C include?Every ATV930C16N4C unit supplied by NANKMOS undergoes pre-shipment functional testing covering power-up verification, communication protocol handshake, and parameter configuration validation. The unit is covered by a 12-month warranty from the date of shipment, with technical support available for installation, commissioning, and network integration queries.
