Allen-Bradley 2198-S160-ERS3 Retrofit Servo Drive for Legacy Systems

Allen-Bradley 2198-S160-ERS3 Retrofit-Compatible Servo Drive for Legacy Motion Systems

The Allen-Bradley 2198-S160-ERS3 is a dual-axis servo drive module within the Kinetix 5700 series, engineered for high-performance motion control in demanding industrial environments. As legacy Kinetix 6000 and Kinetix 6500 installations reach end-of-life, the 2198-S160-ERS3 has become a primary retrofit target for system integrators and maintenance engineers seeking a smooth migration path without full control cabinet redesign. With native EtherNet/IP integration, iTRAK compatibility, and support for the Studio 5000 Logix Designer programming environment, this module delivers a reliable upgrade route for aging servo infrastructure while preserving existing program logic and minimizing commissioning time.

NINERMAS maintains verified stock of the 2198-S160-ERS3 with a 12-month warranty on every unit shipped. Each module undergoes pre-shipment functional testing to confirm axis communication, power stage integrity, and firmware version compatibility before dispatch.

Retrofit Planning for Existing Automation Systems

A successful retrofit of the 2198-S160-ERS3 into an existing production line begins well before the first module is unboxed. Engineers should start by auditing the existing control cabinet for available DIN rail space, DC bus bar routing clearance, and the current power supply module (PSM) capacity. In most Kinetix 6000 installations, the 2094-BCxx-Mxx-S converter must be replaced with a 2198-Pxxx Kinetix 5700 power supply module sized to the total continuous current demand of all axes on the shared bus. The 2198-CAPMOD-2240 shared-bus capacitor module is typically added to stabilize the DC bus during rapid deceleration cycles common in packaging and assembly applications.

On the communication side, legacy SERCOS III fiber ring topologies must be fully replaced with EtherNet/IP copper or fiber infrastructure. This often means adding a managed Ethernet switch — such as a Stratix 5700 or Stratix 2500 — to segment motion traffic from standard I/O traffic on the same ControlLogix or CompactLogix backplane network. The 1756-EN2T or 1756-EN3TR EtherNet/IP bridge module in the controller chassis should be verified for firmware compatibility with the Kinetix 5700 axis objects used in Studio 5000 Logix Designer v32 or later.

Motor feedback wiring is another critical checkpoint. The 2198-S160-ERS3 supports both single-cable (2198-Hxxx motor series) and traditional multi-cable feedback configurations. Where existing MPL or VPL servo motors are retained, the 2090-series feedback cables and 2090-series power cables must be inspected for insulation integrity and connector compatibility with the new drive’s motor port. In cases where motors are also being replaced, the transition to single-cable 2198-Hxxx motors dramatically reduces cabinet wiring complexity and commissioning time.

I/O mapping must be reviewed carefully. Any 1756-IB16 or 1756-OB16E digital I/O modules used for axis-level interlocking, home switch inputs, or overtravel limit signals must be re-mapped in the Logix Designer project to reflect the new axis tag structure. If the existing system uses a 1769-L3x or 1769-L4x CompactLogix controller, verify that the controller firmware supports the Kinetix 5700 Add-On Profile (AOP) before beginning the migration. Older controller revisions may require a firmware upgrade, which itself demands a controlled maintenance window.

HMI screens built on FactoryTalk View ME or FactoryTalk View SE panels — such as the 2711P-T10C21D8S PanelView Plus 7 — will require tag remapping if axis status, fault codes, or position feedback values were previously linked to Kinetix 6000 axis objects. Plan for a dedicated HMI validation session after axis commissioning to confirm all display elements reflect the correct drive status and alarm conditions from the new 2198-S160-ERS3 modules.

Safety circuit validation is non-negotiable. The integrated Safe Torque Off (STO) and Safe Stop 1 (SS1) functions of the 2198-S160-ERS3 must be wired and validated in accordance with IEC 62061 and ISO 13849-1 requirements. If the existing safety architecture uses a 440C-CR30 safety relay or a GuardLogix 5580 safety controller, the safety task in the Logix Designer project must be updated to reflect the new STO wiring topology and response time parameters.

Downtime Control During System Migration

Minimizing production downtime during a Kinetix 5700 retrofit requires a phased migration strategy. The recommended approach is to pre-configure and bench-test the complete 2198-S160-ERS3 axis assembly — including the 2198-Pxxx PSM, DC bus bar, and capacitor module — on a staging rack before the scheduled maintenance window. Use Studio 5000 Logix Designer offline to build and simulate the updated motion program, preserving all existing cam profiles, motion sequences, and MAOC (Motion Axis Output Cam) instructions wherever possible.

During the cutover window, follow a structured sequence: isolate and de-energize the existing Kinetix 6000 system, remove legacy modules from the 2094-series chassis, install the new 2198-series DC bus bar and 2198-S160-ERS3 modules, reconnect motor power and feedback cables, and restore EtherNet/IP network connections. Download the updated Logix Designer project to the controller and perform a controlled axis homing sequence before releasing the line to production. Keep the original Logix Designer project file archived and the legacy 2094-series modules on-site for the first 48 hours post-cutover as a contingency rollback option.

For multi-axis systems with more than four axes, consider a rolling migration — replacing two axes per maintenance window — to limit exposure and allow production to resume on unaffected axes between windows. This approach is particularly effective in automotive body shop and food processing applications where partial line operation is preferable to a full shutdown.

Retrofit Support FAQ

Q1: Is the 2198-S160-ERS3 a direct drop-in replacement for Kinetix 6000 axis modules?
No. While the 2198-S160-ERS3 serves the same functional role as a dual-axis servo drive, it uses a different backplane architecture (DC bus bar vs. 2094-series shared-bus chassis), a different communication protocol stack (EtherNet/IP only, no SERCOS III), and a different motor feedback connector format. A mechanical and electrical retrofit is required, including new PSM, bus bar, and updated Logix Designer axis configuration.

Q2: What firmware version is required in the ControlLogix or CompactLogix controller?
The 2198-S160-ERS3 requires Studio 5000 Logix Designer v32.00 or later and the corresponding Kinetix 5700 AOP (Add-On Profile). Controllers running firmware v28 or earlier must be upgraded. Always verify controller memory capacity after the firmware upgrade, as newer AOP versions consume additional controller memory for axis objects.

Q3: Does NINERMAS provide pre-shipment testing for the 2198-S160-ERS3?
Yes. Every 2198-S160-ERS3 unit shipped by NINERMAS undergoes a functional pre-shipment test covering DC bus power-up, axis communication handshake, STO circuit continuity, and firmware version verification. A test report is available upon request. All units are covered by a 12-month warranty from the date of shipment.

Q4: Can NINERMAS support urgent or emergency orders for the 2198-S160-ERS3?
