Product Introduction
The Allen-Bradley 2094-BC02-M02-S is a Kinetix 6000 Integrated Axis Module (IAM) that combines the line converter and axis inverter in a single 400/460 V AC unit. It provides 15 kW of converter capacity and 15 A continuous inverter current with Safe Torque Off (STO) for machine safety.
This module is chosen for compact, high-performance multi-axis servo systems where space and wiring must be minimized. In field deployments, it’s commonly used in packaging machines, CNC equipment, and coordinated motion systems that rely on the Kinetix 6000 backplane and SERCOS communication.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No status LEDs, module dead | Control power missing or DC bus fault | ✅ High | Measure control power (95–264 V AC) at terminals; check DC bus voltage | Fix control power and DC bus before swapping module |
| STO fault / drive will not enable | Safety circuit open or wiring error | ✅ High | Check STO input wiring and 24 V DC safety supply; verify safety PLC | Correct safety circuit; clear STO fault in controller |
| DC bus overvoltage trip | Regenerative energy, shunt fault, or line spike | ✅ Medium | Monitor DC bus voltage; check internal shunt resistor and wiring | Verify shunt function; reduce decel rate or add external shunt |
| Axis fault on one motor only | Motor wiring, feedback, or encoder issue | ❌ Medium | Check motor phases, brake, and encoder cables; run autotune | Repair motor/feedback; do not replace IAM yet |
| Intermittent faults on multiple axes | Backplane or power distribution issue | ❌ Medium | Inspect Kinetix 6000 backplane connections; check main supply | Repair backplane/power; verify all modules seated correctly |
| Module runs hot or shuts down | Overload, poor airflow, or aging fans | ✅ Medium | Measure module temperature; check cabinet airflow and filters | Improve cooling; verify load within 15 A continuous rating |
If you’re stuck, send photos of the module (including status LEDs), a screenshot of the fault codes from Logix/RSLogix, and a one-line diagram of your Kinetix 6000 system. We’ll review it before you swap the module.

Frequently Asked Questions (FAQ)
Q: Is the 2094-BC02-M02-S hot-swappable?
A: No. Kinetix 6000 IAMs must be installed and removed with AC power and DC bus OFF. Hot-swapping can damage the backplane and other drives.
Q: What’s the difference between 2094-BC02-M02-S and 2094-BC02-M02-M?
A: Both are 15 kW / 15 A IAMs. The “-S” suffix indicates Safe Torque Off (STO) safety functionality. The “-M” version lacks STO. Do not substitute without verifying your safety design.
Q: Can I use this module in a Kinetix 5700 system?
A: No. The 2094-BC02-M02-S is for Kinetix 6000 backplanes only. Kinetix 5700 uses different modules (e.g., 2198-…). For new designs or replacements, Rockwell recommends migrating to the 2198 family.
Q: What condition are these modules in, and why is pricing lower than factory?
A: We sell New Original (New Surplus) and Refurbished (tested) units. Pricing is lower because these are surplus or professionally refurbished, and Rockwell has discontinued the Kinetix 6000 IAM line. Each refurbished unit goes through load testing and comes with a 1-year warranty.
Q: Do I need to reconfigure the system when replacing a failed 2094-BC02-M02-S?
A: Usually no. If the replacement is the same catalog number and firmware level, the existing Motion configuration in Logix should work. Always back up the project and verify axis parameters after swap.
Q: Can I run this module without the Kinetix 6000 backplane?
A: No. The 2094- requires the Kinetix 6000 backplane for control power distribution, SERCOS communication, and system coordination. It is not a stand-alone drive.
Q: What is the recommended replacement for the 2094-?
A: Rockwell lists 2198-D032-ERS3 (Kinetix 5700 / iTRAK family) as the engineering replacement. Migration requires new hardware, backplane, and project conversion in Studio 5000.
