In short
Replacing a faulty Kinetix 5500 2198-H008-ERS2 drive? This expert guide covers technical specifications, drop-in replacement options, firmware adjustments, and step-by-step replacement steps.
Overview
The Allen-Bradley Kinetix 5500 servo drive family is a cornerstone of modern, integrated motion control systems operating on EtherNet/IP networks. Within this system, the 2198-H008-ERS2 serves as a vital mid-range drive, providing precise control over continuous and peak current outputs in packaging, material handling, assembly, and converting applications.
The standout feature of the 2198-H008-ERS2 is its support for Integrated Safety over EtherNet/IP (CIP Safety), which allows safety functions to be configured and run directly through Studio 5000 Logix Designer without hardwired safety circuits. When this drive fails, finding a quick, compatible replacement is paramount to restoring line uptime. This guide details the specifications, direct drop-in alternatives, upgrade considerations, and a comprehensive physical and programmatic replacement procedure.

Recommended Replacements
If you are replacing a faulty 2198-H008-ERS2, you have several options depending on physical availability, upgrade footprints, and network safety architecture.
| Replacement Model | Type | Compatibility Level | Technical Differences / Considerations |
|---|---|---|---|
| 2198-H008-ERS2 | Direct Match | Exact Drop-in | No physical cabinet modifications required. Requires firmware configuration and safety network signature reset to match legacy configuration. |
| 2198-H015-ERS2 | Frame Size Upgrade | Functional / Over-Sized | Continuous output current increases to 5.0 A (15 A peak). Fits Frame 2 footprints. This drive is wider (55mm vs. 50mm) and requires updating the controller axis scaling and output profile in Studio 5000. Useful if the 2.5 A threshold was marginally stressed. |
| 2198-H008-ERS | Hardwired Safety Alternative | Conditional Alternative | Matches physical Frame 1 dimensions and current specs. However, it uses Hardwired Safe Torque Off instead of network-based CIP Safety. Replacing an "ERS2" with an "ERS" requires adding physical safety relays, dynamic I/O wiring, and heavily modifying the Logix Designer I/O tree configuration. |
Compatibility Considerations
Before hot-swapping or commissioning a replacement drive, review these critical system and firmware dependencies:
1. Studio 5000 Logix Designer Version
Integrated Safety (-ERS2) requires specific Add-On Profiles (AOP) within Studio 5000 Logix Designer. Depending on your GuardLogix controller (5570/5580 or Compact GuardLogix 5370/5380), you must ensure your programming software matches the configuration format of the drive firmware.
- Studio 5000 V24 or newer is highly recommended to properly configure major revision 2 or later firmware on Kinetix 5500 drives.
- Firmware Compatibility: Ensure the firmware minor version on the replacement drive matches or is compatible with the version defined in your Logix Designer I/O tree configuration (Compatible Keying setup).
2. GuardLogix Safety Network Number (SNN)
The Integrated Safety configuration links the GuardLogix CPU and the 2198-H008-ERS2 using a Safety Network Number. A brand-new or used replacement drive will reject Ethernet communications from the controller with an SNN mismatch error. The replacement drive's SNN must be cleared to its out-of-box state before the controller can write its own active safety signature to the unit.
3. Shared Bus Bar Structures
If your drive is mounted on a shared AC/DC bus bar system (utilizing accessories like the 2198-BARCON-55DCAC100 bus bars), you must ensure that mechanical alignment with adjacent drives is pristine. Attempting to force different frame sizes together without matching spacer blocks can strain the multi-drive bus connectors.
Upgrade Benefits
Using a genuine replacement like the 2198-H008-ERS2, or upsizing to the high-capacity -ERS2 modules, provides engineering benefits over older, hardwired-only legacy systems:
- Decreased Wiring Complexity: By managing Safe Torque Off command chains over Ethernet, you bypass dozens of terminal blocks, auxiliary relays, and physical feedback circuits prone to high-vibration failures.
- Enhanced Performance Metrics: Newer firmware on the 2198-H008-ERS2 yields superior diagnostic monitoring of internal intermediate circuit voltages, motor temperatures, and feedback quality.
- Reduced Spare Inventory footprint: Supporting a wide scope of VP-Series motors on a single, network-managed platform means fewer single-purpose specialized drives sitting in warehouses.
Common Migration Challenges
Technicians often run into specific speed bumps when swapping out a 2198-H008-ERS2:
- The "F15" (Feedback Loss) Fault: Often caused by poor shield contacts on the single Motor/Feedback Hiperface DSL cable (2090-CSBM1DF). It is crucial to clamp the cable shield directly to the drive ground plate.
- Logix Error 16#011e (Connection Fault - SNN Mismatch): Occurs when a populated safety signature is detected on the replacement unit. This drive must be programmatically "reset to factory default" inside Studio 5000 to purge the safety signature of its previous machine home.
- Electronic Keying Faults: If the current project utilizes "Exact Match" electronic keying, any discrepancy in the minor or major firmware revisions of the new hardware will prevent the ControlLogix processor from establishing a running connection.

Phase 1: Safe Physical Removal
- LOTO (Lockout / Tagout): Disconnect and lock out main 3-phase inbound AC power (480V/240V). De-energize the 24VDC control supply to the drive logic board.
- Capacitor Discharge Time: Wait at least 5 minutes for internal capacitor banks to discharge. Using a reliable digital multimeter calibrated for 1000VDC, measure from the DC+ to DC- power terminals on the shared bus link (or top bus connections) to confirm the voltage is under 50VDC before touching anything.
- Connector Removal: Carefully label and disconnect:
- Dual RJ45 EtherNet/IP communication cables.
- Mains power supply feed plug (IPD).
- Motor power and single DSL motor feedback plug (MP).
- 24V auxiliary power plug (AP).
- Remove Bus Bars: If the drive is integrated into a multi-axis system, remove the plastic safety covers and unscrew the shared bus line connectors (2198-BARCON).
- Physical Demounting: Loosen the mounting screws (or the DIN rail clamp retention mechanism) and slide the old drive out of the panel.
Phase 2: Installing the New 2198-H008-ERS2
- Verify Orientation: Keep minimum clearances around Frame 1 drives: 50 mm (1.97 in.) on top, 100 mm (3.94 in.) on bottom, and zero spacing between adjacent Kinetix 5500 drives on a shared bus.
- Mounting: Hook the drive onto the back plate and tighten the mounting fasteners or secure the DIN rail lock.
- Re-establish Grounding: Clean any oxidation on the subplate where the chassis contacts it. Securely lock down the single DSL feedback cable shield in the drive's grounding clamp to prevent high-frequency EMI noise.
- Re-wire Connections: Plug back in the Motor feedback/power connector (MP), mains connector (IPD), the Ethernet linkages, and the 24V DC control connector (AP).
- Bus Bar Reassembly: Retitrate the shared bus connectors strictly within manufacturer torque tolerances using appropriate driver heads to avoid thermal hotspots down the line.
Phase 3: Controller Commissioning and IP Assignment
- Auxiliary Boot: Power on only the 24V DC auxiliary control logic power. Leave primary 480V mains turned off.
- IP Configuration: Configure the IP address of the new unit. This can be accomplished on the front LCD screen using the mechanical select buttons, or by leveraging a BOOTP/DHCP Server. If utilizing the front panel:
- Navigate to
Network Settings->IP Mode. - Set the default configuration to
Static IPand input the exact IP Address, Subnet Mask, and Gateway matching the original design document.
- Navigate to
- Firmware Alignment: Check the current firmware version visible on the display. If a mismatch is flagged in Studio 5000, launch ControlFlash or ControlFlash Plus, select your target drive node over EtherNet/IP, and flash the target firmware catalog definition block.
Phase 4: Network Safety Commissioning (SNN Reset)
- Open your active Studio 5000 Logix Designer project.
- If online with the GuardLogix controller, the CPU’s target drive connection will output a fault. Go to the properties page of the newly swapped
2198-H008-ERS2under the IO configuration tree. - Select the Safety tab.
- Click on the Reset ownership icon, or clear the Safety Network Number (SNN) setting. This deletes existing safety signatures.
- Apply the modifications. The GuardLogix project SNN will copy down to the clean drive automatically.
- Verify safety device synchronization. The drive safety validation indicators on your HMI/Logix environment should transition to a running Status.
- Restore main AC feed lines, confirm logic permissive signals, and execute brief motion jog sequences.
Frequently Asked Questions
Can I replace a 2198-H008-ERS2 with a 2198-H008-ERS?
No, not directly without rewriting critical safety systems. The -ERS version relies on hardwired Safe Torque Off safety loops, whereas the -ERS2 relies on Integrated Safety over EtherNet/IP (CIP Safety). If your network PLC configuration calls for a CIP Safety device via EtherNet/IP, the CPU cannot communicate safety commands over an -ERS drive.
What is the discharge time for a Kinetix 5500 Frame 1 drive?
The minimum suggested wait time is 5 minutes. Never touch dynamic terminals or the shared AC/DC bus bars immediately after disconnecting supply power. Always verify with a digital multimeter that DC-to-DC bus terminals read below 50VDC.
What if I get an "F15" feedback fault after replacing the drive?
An F15 fault indicates feedback loss from the Hiperface DSL continuous encoder stream. This is typically caused by a loose connection at the single motor cable connector, or EMI electrical noise bleeding into the feedback lines. Ensure you use a genuine 2090-CSBM1DF series cable and clamp the raw shield layer directly into the integrated ground plate frame on the bottom of the Kinetix 5500 drive.
Do I have to compile and write new PLC code to commission the new drive?
No, the main logic and servo motion parameter sets are saved locally in the GuardLogix or ControlLogix PLC processor. Once you configure the correct IP Address, verify compatible firmware keying, and clear the Safety Network Number (SNN), the controller will push down parameter profiles to the drive automatically over Ethernet.
