Allen-Bradley Kinetix 5700 — Overview
The Allen-Bradley Kinetix 5700 (2198-Dxxx inverter modules, 2198-Pxxx power supplies) is Rockwell's DC-bus-shared servo architecture designed for multi-axis industrial machines. With power ratings from 1.5 to 55 kW and support for up to 32 axes on a common DC bus, the Kinetix 5700 is deployed in CNC machining centers, robotic cells, packaging lines, and material handling systems where synchronized motion and regenerative energy sharing are critical. Each inverter module connects to a shared power supply, reducing cabinet footprint and electrical infrastructure costs.
Component-level repair makes strong economic sense for Kinetix 5700 systems. New inverter modules range from $4,000 to over $15,000 depending on power rating, while our repairs typically cost $900–$2,800. Because the Kinetix 5700 uses modular inverter cards with discrete IGBT modules, gate drivers, and feedback circuits, most failures can be traced to specific semiconductor or power stage components. Our technicians repair at the board level, test under load, and verify EtherNet/IP communication and motion profile execution before return.

Common Kinetix 5700 Failures We Repair
Every failure repaired at component level — root cause fixed, not just the fault code cleared.
IGBT / IPM Power Module Failure
High-frequency switching stress, inductive load spikes, or DC bus overvoltage events cause IGBT junction failure or IPM thermal shutdown. Symptoms include FLT-S29 (Hardware Overcurrent) or FLT-S43 (IPM Fault). We replace failed IGBT modules, gate driver ICs, and test under rated load with back-EMF simulation to verify thermal performance and switching integrity.
DC Bus Capacitor Degradation
Electrolytic capacitors in the DC link lose capacitance over time due to ripple current and ambient heat, causing FLT-S10 (Bus Undervoltage) or erratic torque output. We measure ESR and capacitance, replace aged capacitors with high-ripple-rated equivalents, and verify DC bus stability under regenerative braking conditions.
Encoder Feedback Interface Failure
Hiperface DSL or EnDat transceiver ICs fail due to electrical noise, ground loops, or cable faults, triggering FLT-S22 (Encoder Feedback Loss). We diagnose differential signal integrity, replace failed transceivers or opto-isolators, and validate bidirectional encoder communication at full speed to ensure sub-arc-second position accuracy.
Gate Driver Circuit Failure
Gate driver ICs (often IR2110, 2ED020I12, or similar) fail from shoot-through events or dV/dt-induced latch-up, preventing IGBT switching. This causes no motor response or immediate FLT-S29 faults. We replace gate driver ICs, bootstrap diodes, and gate resistors, then perform safe short-circuit testing to confirm deadtime and desaturation protection.
Control Board / DSP Processor Failure
The main control board houses the TI TMS320 DSP and EtherNet/IP ASIC; failures here cause loss of network communication, parameter corruption, or failure to initialize. We diagnose power rail sequencing, replace failed processors or memory ICs, reflash firmware, and verify motion profile execution and CIP Sync timing.
Power Supply (2198-P) Rectifier / Inrush Failure
Three-phase bridge rectifiers and NTC inrush limiters in the 2198-P power supply fail from repetitive start cycles or supply transients, causing no DC bus voltage or FLT-S10. We replace bridge modules, inrush thermistors, and pre-charge relays, then load-test at full rated current to verify bus regulation and ripple.
Kinetix 5700 Fault Codes Reference
Common fault codes seen on the 2198-Dxxx / 2198-Pxxx series — what they mean and when to call for repair.
| Code | Name | Cause & Fix |
| FLT-S07 | Motor Overload | Thermal model indicates prolonged overcurrent; caused by mechanical binding, incorrect motor parameters, or inadequate cooling—verify I²t limits and inspect IGBT thermal interface. |
| FLT-S09 | Bus Overvoltage | DC bus exceeds 747V due to regenerative energy or braking resistor failure—check regen resistor, shunt regulator, and bus capacitor health. |
| FLT-S10 | Bus Undervoltage | DC bus drops below minimum (typically <540V) due to AC supply sag, failed rectifier, or degraded bus capacitors—measure input voltage and capacitor ESR. |
| FLT-S22 | Encoder Feedback Loss | Loss of Hiperface DSL or EnDat communication caused by cable damage, transceiver failure, or encoder power loss—verify encoder supply voltage and differential signal integrity. |
| FLT-S29 | Hardware Overcurrent | Instantaneous overcurrent detected via desaturation or shunt sensing, indicating IGBT failure, shoot-through, or phase-to-ground fault—replace power module and gate driver circuit. |
| FLT-S43 | IPM Fault | Intelligent Power Module reports thermal shutdown or internal fault via dedicated fault pin—caused by heatsink failure, fan loss, or IGBT degradation; replace IPM and verify thermal management. |
| FLT-M07 | Motor Wiring Issue | Drive detects asymmetric phase current or open motor winding during autotune or operation—inspect motor cable, contactor contacts, and phase-to-phase resistance. |
| FLT-S01 | Drive Overtemperature | Heatsink or internal temperature sensor exceeds safe limit due to blocked airflow, fan failure, or ambient overtemperature—clean heatsink, replace fan, verify thermal shutdown circuit. |

Kinetix 5700 Repair — FAQ
Answers to the most common questions about our Allen-Bradley Kinetix 5700 (2198-Dxxx / 2198-Pxxx series) servo drive repair service
How much does Kinetix 5700 repair cost?
Kinetix 5700 repair at Flexa Systems typically costs between $900 and $2,800 depending on the fault and power rating, compared to $4,000–$15,000+ for new OEM replacement. We offer free diagnostics, and every repair is backed by our 2-year warranty with a no-fix no-charge guarantee.
What is the most common Kinetix 5700 failure?
The most common failure is IGBT or IPM power module degradation, often triggered by repetitive inductive load switching, DC bus overvoltage events during regenerative braking, or thermal cycling. This typically presents as FLT-S29 (Hardware Overcurrent) or FLT-S43 (IPM Fault). We replace the power stage, gate driver circuit, and load-test under full rated current.
How long does Kinetix 5700 repair take?
Standard Kinetix 5700 repair turnaround is 5–10 business days from receipt, including diagnostics, component-level repair, firmware validation, and full motion profile testing. Rush service is available with 48–72 hour turnaround for critical production downtime situations.
Do you repair discontinued Kinetix 5700 drives?
Yes, we repair discontinued and obsolete Kinetix 5700 models. Because we work at the component level—replacing IGBTs, gate drivers, capacitors, and control ICs—we are not dependent on OEM part availability. We maintain an inventory of equivalent semiconductors and have circuit-level documentation for legacy inverter modules.
Will my Kinetix 5700 parameter and motion settings be preserved?
Yes. Component-level repair preserves your drive's firmware and stored parameters in non-volatile memory. We do not reflash or reset configuration unless the control board memory IC has failed. Your motion profiles, tuning gains, and EtherNet/IP node address remain intact, minimizing recommissioning time.
What is your warranty on Kinetix 5700 repairs?
Every Kinetix 5700 repair from Flexa Systems is backed by a comprehensive 2-year warranty covering parts and labor. If we cannot successfully repair your drive, there is no charge—our no-fix no-charge guarantee ensures you only pay for verified, functional repairs.
