Product Details

2198-D012-ERS3 Product Description

The Allen-Bradley 2198-D012-ERS3 is a dual-axis EtherNet/IP servo drive from the Kinetix 5500 series, engineered to serve as a high-performance motion control node within modern smart factory data architectures. Rated at 3 A continuous output current per axis, this drive integrates CIP Motion protocol natively over a standard EtherNet/IP network, enabling seamless, deterministic communication between field-level actuators and upper-level control systems without the need for proprietary fieldbus adapters or protocol conversion hardware. In an era where manufacturing transparency, real-time diagnostics, and data-driven production optimization define competitive advantage, the 2198-D012-ERS3 delivers the connectivity backbone that links servo motion directly into the plant-wide information fabric.

From the moment a motion command originates in a Logix 5000 controller — such as the CompactLogix 5380 or ControlLogix 5580 — the 2198-D012-ERS3 receives, interprets, and executes it with sub-millisecond cycle synchronization. The drive's integrated EtherNet/IP port connects directly to the plant network, allowing Studio 5000 Logix Designer to configure, commission, and monitor both axes from a single engineering workstation. This eliminates the traditional boundary between motion control and process data, making servo position, velocity, torque, bus voltage, and fault codes all visible to SCADA platforms such as FactoryTalk View SE or Ignition SCADA in real time.

In a fully connected smart factory, the 2198-D012-ERS3 occupies a critical position in the motion data chain. At the field level, MPL-B310P-MJ72AA servo motors connect to each axis of the drive via Kinetix feedback and power cables, delivering high-resolution position and velocity data back to the drive's internal motion engine. The drive then aggregates this real-time axis data and transmits it upstream over EtherNet/IP to the CompactLogix 5380 controller, which executes coordinated multi-axis motion programs written in Studio 5000.

Alongside the servo drive on the same EtherNet/IP segment, a 1783-BMS10CGL Stratix 5700 managed industrial Ethernet switch provides the network infrastructure, supporting Device Level Ring topology for media redundancy — ensuring that a single cable fault does not interrupt production. The switch connects the 2198-D012-ERS3, the CompactLogix controller, a PanelView Plus 7 HMI terminal, and a 1734-AENTR POINT I/O EtherNet/IP adapter that aggregates digital and analog I/O signals from proximity sensors, photoelectric sensors, and pressure transducers distributed across the production line.

For variable-speed conveyor and pump applications running in parallel with the servo axes, a PowerFlex 525 AC drive communicates over the same EtherNet/IP network, allowing the Logix controller to coordinate servo motion timing with conveyor belt speed in a synchronized production sequence. Analog sensor signals — including 4–20 mA current loop outputs from temperature and flow transmitters — are digitized by the 1734 POINT I/O modules and made available to the controller as process variables, which are then forwarded to the FactoryTalk Historian server for long-term trending and OEE analysis.

At the edge, a 1783-ETAP2F EtherNet/IP Tap provides passive network monitoring capability, enabling a Cisco IE 4000 industrial edge switch to mirror traffic for network diagnostics without disrupting live production communications. An Allen-Bradley 9300-ENA EtherNet/IP-to-serial gateway bridges any legacy RS-232 or RS-485 devices — such as older barcode readers or weighing terminals — into the EtherNet/IP data fabric, eliminating isolated data islands that would otherwise require manual data entry. The complete data chain — from servo encoder pulses through EtherNet/IP packets to SCADA dashboards — is fully traceable, time-stamped via CIP Sync (IEEE 1588 PTP), and available for remote access through FactoryTalk Remote Access or a secure VPN gateway.

Many automation sites operating legacy motion systems face a common set of challenges: servo drives that communicate only over proprietary networks such as SERCOS or analog ±10 V command interfaces, creating protocol islands that SCADA systems cannot reach without custom middleware. The 2198-D012-ERS3 resolves this by natively speaking EtherNet/IP and CIP Motion — the same protocol stack used by the plant's Logix controllers, managed switches, and HMI terminals — so no additional protocol converter hardware is required between the drive and the control layer.

Data silos are further eliminated because the drive exposes all axis parameters — including following error, bus voltage, regenerative energy, and active faults — as standard CIP objects that any EtherNet/IP-capable SCADA or MES system can poll directly. Remote diagnostics become practical: a maintenance engineer can connect to the drive through Studio 5000 or FactoryTalk Diagnostics from any networked workstation, read real-time axis status, acknowledge faults, and adjust tuning parameters without physically accessing the control cabinet. Alarm events are time-stamped at the drive level using CIP Sync, ensuring that fault sequences are accurately reconstructed in the historian even when multiple axes trip simultaneously.

For production line transparency, the drive's dual-port EtherNet/IP interface supports Device Level Ring topology, which means the network remains operational even if a cable is accidentally disconnected — a critical requirement for 24/7 continuous production environments. System expansion is straightforward: additional Kinetix 5500 drives, such as the 2198-D020-ERS3 (6 A) or 2198-D032-ERS3 (11 A) for higher-power axes, can be added to the same EtherNet/IP segment and commissioned in Studio 5000 without modifying the network architecture. This scalability protects the initial infrastructure investment as production capacity grows.

Q1: What is the communication latency of the 2198-D012-ERS3 over EtherNet/IP?The 2198-D012-ERS3 supports CIP Motion with a minimum Requested Packet Interval (RPI) of 0.5 ms per axis, enabling deterministic, low-latency motion control synchronized across multiple drives via CIP Sync (IEEE 1588 PTP). This is suitable for high-speed coordinated motion applications including electronic gearing and cam profiling.

Q2: Is the 2198-D012-ERS3 compatible with third-party SCADA and HMI systems?Yes. Because the drive communicates over standard EtherNet/IP using CIP objects, it is accessible to any SCADA or HMI platform with an EtherNet/IP driver — including Ignition SCADA, Wonderware System Platform, and Siemens WinCC via third-party EtherNet/IP OPC-UA bridges. Native integration is available with FactoryTalk View SE and FactoryTalk Historian.

Q3: How does the drive support network redundancy and stability?The dual-port EtherNet/IP interface supports Device Level Ring (DLR) topology, providing automatic media redundancy with sub-3 ms recovery time in the event of a single network fault. This ensures uninterrupted motion control and data communication in production environments where network downtime is not acceptable.

Q4: What pre-shipment testing and warranty coverage is provided?Every 2198-D012-ERS3 unit supplied by NANKMOS undergoes functional verification testing prior to shipment, including power-on self-test, communication port validation, and axis enable verification. All units are covered by a 12-month warranty from the date of shipment. In-stock units are available for immediate dispatch to support urgent project timelines.
