We diagnose and repair IGBT failures, encoder faults, bus overvoltage, and IPM issues at a fraction of OEM replacement cost. Free diagnostics and no-fix no-charge guarantee on every repair.
Allen-Bradley Kinetix 6500 — Overview
The Allen-Bradley Kinetix 6500 is a modular multi-axis servo drive system designed for high-performance motion control in CNC machine tools, packaging equipment, converting lines, and industrial robotics. Built as a modular multi-axis platform, the Kinetix 6500 supports single-axis and multi-axis configurations with power ratings from 1.8 to 22 kW per axis and 324–528V three-phase operation. It communicates over EtherNet/IP with Integrated Motion and accepts Hiperface, EnDat, TTL incremental, sin/cos and Tamagawa feedback.
Because the Kinetix 6500 is an older platform, replacement options can be limited and costly. Component-level repair by Flexa Systems extends the operational life of your installed base, preserves existing machine configurations, and eliminates the need for costly hardware upgrades or system revalidation—often saving 30–60% compared to buying new.

Common Kinetix 6500 Failures We Repair
Every failure repaired at component level — root cause fixed, not just the fault code cleared.
IGBT / IPM Power Module Failure
Short-circuit events, thermal cycling, and DC bus transients cause IGBT degradation or catastrophic failure. Symptoms include FLT S10 (Inverter Overcurrent, the IPM fault) or FLT S16 (Ground Current) that return with the motor and cable proven good, or no drive power-up. We replace failed power modules with OEM-equivalent components, test under load, and verify gate drive integrity before return to service.
DC Bus Capacitor Degradation
Electrolytic capacitors in the DC bus age over time, leading to reduced capacitance, increased ESR, and DC-bus faults such as FLT S35 (Bus Overvoltage) or FLT S33 (Bus Undervoltage). This is especially common in drives operating in high-temperature environments or continuous-duty cycles. We perform ESR testing and replace all affected capacitors with high-temperature rated components.
Encoder Feedback Interface Failure
Damaged encoder input circuitry from cable faults, ESD events, or improper wiring causes FLT S43 (Motor Feedback Loss) faults. We diagnose differential receiver ICs, isolation circuits, and power supply rails on the feedback board. Repairs restore compatibility with Hiperface DSL, sin/cos, and resolver feedback devices.
Gate Driver Circuit Faults
Gate driver ICs and bootstrap circuitry fail due to thermal stress or IGBT short-circuit events, preventing proper switching and triggering IPM faults or no motor drive. We replace damaged gate driver stages, verify isolation transformer integrity, and confirm proper gate signal timing under no-load and full-load conditions.
Control Board / Processor Failures
Microcontroller faults, corrupted firmware flash memory, or failed voltage regulators prevent drive initialization or cause erratic motion behavior. We replace damaged control board components, reflash firmware where applicable, and verify EtherNet/IP and SERCOS communication integrity after repair.
Overload and Thermal Shutdown
FLT S07 (Motor Overload) faults result from a duty cycle that needs more RMS current than the motor's continuous rating, undersized motor selection, or mechanical binding. We verify current sensing circuits, thermistor input conditioning, and power stage thermal management. Component-level repair addresses root causes including failed current sensors and thermal interface degradation.
Kinetix 6500 Fault Codes Reference
Fault codes as printed in Allen-Bradley user manual 2094-UM002 for the 2094-EN02D control modules on 2094 IAM/AM power modules. The display scrolls them as FLT Sxx followed by a short description.
| Code | Name | Cause & Fix |
| FLT S10 | INV OVERCURRENT | IPM fault: power transistors turned off for overcurrent, overtemperature or a power supply problem. Check motor cable continuity, vents, fan and ambient, reduce acceleration. Continuity from the DC bus to U/V/W with power removed means the module needs repair; replace the module if its fan has failed. |
| FLT S16 | GROUND CURRENT | Excessive ground current in the converter: wiring error, motor ground short or internal malfunction. Disconnect the motor cable and enable with current limit 0 — if the fault stays, the module itself is faulty. |
| FLT S35 | BUS OVERVOLT FL | DC bus above the factory limit from excessive regeneration (460V bus over 820V). Change the deceleration profile, use a larger system or install a shunt module. |
| FLT S33 | BUS UNDERVOLT FL | DC bus below limits with three-phase power present (460V system below 275V). Verify incoming AC, check for glitches or line drop, disable follower axes before removing power. |
| FLT S23 | AC PHASE LOSS | Some but not all AC input phases are absent (sub-code 01, 02, 03 = L1, L2, L3). Check AC input voltage on all phases. |
| FLT S18 | CONV OVERTEMP FL | The IAM converter thermal switch tripped from excessive heat in the power circuitry. Reduce acceleration and duty cycle, use a larger IAM, check vents, fan and clearance. |
| FLT S29 | SHUNT OVERLOAD FL | The shunt thermal model exceeded its rating. Use a properly sized shunt, modify the duty cycle, or add an external shunt to the internal one. |
| FLT S07 | MTR OVERLOAD FL | Motor thermal model above 110% of rating: duty cycle needs RMS current above the motor continuous rating. Reduce speed or increase time in the command profile. |
| FLT S43 | MTR FDBK LOSS FL | Feedback signal amplitude below the factory limit: motor or aux feedback wiring open, shorted or missing. Check encoder wiring and run the Hookup test. |
| FLT S54 | POSN ERROR | Position error limit exceeded: undersized drive or motor, or mechanics out of specification. Check gains, limits, sizing and motor power wiring. |
| NODE FLT 06 | LOST CTRL CONN | Communication with the controller was lost. Check the Ethernet cable and controller operation. |
| FLT M27 | BACKPLANE COMM | Backplane communication fault. Cycle control power, reseat the modules or replace the faulty module. |

Kinetix 6500 Repair — FAQ
Answers to the most common questions about our Allen-Bradley Kinetix 6500 (2094-EN02D / 2094-BCxx / 2094-BMxx series) servo drive repair service
How much does Kinetix 6500 repair cost?
Flexa Systems repairs Allen-Bradley Kinetix 6500 drives for $800–$2,500 depending on the failure mode and axis modules affected. All repairs include free diagnostics, component-level troubleshooting, and a 2-year warranty. We offer a no-fix no-charge guarantee, so you only pay if we successfully restore your drive to OEM specifications.
What is the most common Kinetix 6500 failure?
IGBT and IPM power module failures are the most common fault mode in Kinetix 6500 drives, typically triggered by short-circuit events, DC bus transients, or thermal cycling. These failures manifest as FLT S10 (Inverter Overcurrent) IPM faults. DC bus capacitor degradation is the second most frequent issue, especially in drives with over 40,000 operating hours.
How long does Kinetix 6500 repair take?
Most Kinetix 6500 repairs ship in 5–30 business days from receipt to shipment. Rush service is available with 24–72 hour turnaround for critical production equipment. All repairs undergo full load testing and multi-point inspection before release. Contact us at (254) 254-0005 to discuss expedited service options.
Do you repair discontinued Kinetix 6500 drives?
Yes. Flexa Systems specializes in repairing discontinued Allen-Bradley servo drives including the Kinetix 6500 series. With OEM replacement parts scarce and new drives no longer available, component-level repair is the most cost-effective and fastest solution to restore your motion system. We maintain an extensive library of schematics and replacement components for legacy Kinetix platforms.
Will my Kinetix 6500 parameter and motion settings be preserved?
Yes. Component-level repair preserves all drive configuration parameters, motion profiles, EtherNet/IP settings, and axis tuning stored in non-volatile memory. Unlike board-level exchanges or drive replacements, our repair process does not require re-commissioning, motion tuning, or program updates—minimizing downtime and eliminating the need for controls engineering support during reinstallation.
What is your warranty on Kinetix 6500 repairs?
Flexa Systems provides a 2-year warranty on all Kinetix 6500 servo drive repairs, covering parts and labor. If your repaired drive fails due to a workmanship or component defect within the warranty period, we will re-repair or replace it at no charge. We also offer a no-fix no-charge guarantee: if we cannot successfully repair your drive, you pay nothing.
