KUKA 00-217-026 Retrofit Power Supply for Legacy Systems

KUKA 00-217-026 Retrofit Power Supply for Legacy Systems

The KUKA 00-217-026 (also referenced as 00217026D3236-K13) is a critical power supply module designed for use within the KUKA KR C2 and KR C3 robot controller platforms — two of the most widely deployed industrial robot controller generations in automotive, metal fabrication, and general manufacturing environments worldwide. As KUKA has progressively transitioned its installed base toward the KR C4 and iiQKA ecosystems, the 00-217-026 has become an essential retrofit and replacement component for facilities that continue to operate legacy KR C2 and KR C3 systems and require a reliable, tested, and immediately available spare to avoid unplanned downtime.

NINERMAS COMPANY LIMITED maintains verified stock of the KUKA 00-217-026 power supply module, pre-shipment tested and covered under a 12-month warranty from the date of delivery. Each unit is inspected for output voltage stability, thermal performance, and connector integrity before dispatch, ensuring that your replacement module arrives ready for installation without additional bench testing delays on-site.

Retrofit Planning for Existing Automation Systems

When planning a retrofit or emergency replacement of the KUKA 00-217-026 within an active production environment, a structured approach to component verification and sequenced installation is essential to protect both the controller hardware and the existing robot program logic stored on the KR C2 system PC.

Before removing the failed power supply, maintenance engineers should archive the current robot program from the KCP2 teach pendant, ensuring that all motion sequences, tool data, base coordinates, and I/O assignments are backed up to an external storage device. The KCP2 teach pendant itself should be inspected for cable integrity at this stage, as the pendant cable connector at the controller cabinet is a common wear point on high-cycle KR C2 installations.

The KR C2 controller cabinet houses several interdependent modules that must be assessed during any power supply replacement. The CCU (Cabinet Control Unit) board manages the safety and E-stop logic and draws its 24V DC supply directly from the power supply module being replaced. Similarly, the RDW (Resolver Digital Converter) card, which handles encoder signal processing for each robot axis, relies on the ±15V DC analog rails provided by the 00-217-026. If either of these rails is degraded rather than completely failed, intermittent axis faults or resolver errors may have been the presenting symptom before the power supply was identified as the root cause.

The KSP 600-3×40 servo pack and KPP 600-20 power pack — the drive-side components within the KR C2 cabinet — should be inspected for DC bus voltage integrity once the new 00-217-026 is installed and the logic supplies are confirmed stable. In some KR C2 installations, a degraded power supply module causes the KPP 600-20 to log DC bus undervoltage faults, which clear automatically once the logic supply is restored to specification. Engineers should not replace the KPP 600-20 or KSP 600-3×40 servo pack without first confirming that the root cause was the power supply and not a drive-side fault.

For facilities running Profibus DP networks, the existing Profibus communication card within the KR C2 controller should be retained during the power supply swap. No re-addressing or network reconfiguration is required for a like-for-like 00-217-026 replacement. However, if the retrofit is being combined with a broader system upgrade — for example, migrating from KR C2 to KR C4 — the Profibus master configuration in the PLC (such as a Siemens S7-300 or S7-400 series controller) will need to be updated to reflect any changes in the robot’s GSD file or I/O mapping.

Where the retrofit involves I/O expansion or signal isolation — for example, adding new end-of-arm tooling signals or integrating a vision system — signal isolators and terminal expansion modules should be wired and tested before the robot controller is powered up. Confirming that all 24V DC I/O signals are within tolerance at the terminal strip level prevents nuisance faults during the first power-up sequence after the replacement.

Installation space within the KR C2 cabinet is fixed, and the 00-217-026 occupies a defined slot position. Engineers should confirm the slot assignment against the cabinet wiring diagram before removal to avoid disturbing adjacent modules such as the ESC (Electronic Safety Circuit) board, which manages the safety-rated E-stop and safeguard monitoring functions. Disturbing the ESC board connections without a controlled re-commissioning procedure can trigger safety faults that require a full safety acceptance test before the robot can be returned to automatic mode.

Downtime Control During System Migration

Minimizing downtime during a KUKA 00-217-026 replacement requires pre-staging the replacement module, tools, and documentation before the maintenance window begins. NINERMAS ships the 00-217-026 with a pre-shipment test report confirming output voltage measurements on all rails, allowing the receiving engineer to verify the module against specification before the planned shutdown rather than discovering a discrepancy during the replacement window itself.

The recommended replacement sequence is: (1) archive robot program and I/O configuration from the KCP2 teach pendant; (2) isolate and lock out the cabinet power supply at the main disconnect; (3) photograph the existing wiring and connector positions before removal; (4) remove the failed 00-217-026 and install the replacement, reconnecting all terminals in the documented sequence; (5) restore power and verify all output rails with a calibrated multimeter before enabling the servo drives; (6) perform a controlled axis enable sequence, monitoring for any residual faults on the KCP2 display; (7) run a slow-speed program verification cycle before returning the robot to full automatic production speed.

For facilities with redundant robot cells, a rolling replacement strategy — replacing one controller at a time while adjacent cells maintain production — can eliminate the need for a full line shutdown. NINERMAS maintains buffer stock of the 00-217-026 to support multi-unit orders for facilities implementing a planned preventive replacement program across an aging KR C2 fleet.

Retrofit Support FAQ

Q: Is the KUKA 00-217-026 a direct replacement for all KR C2 and KR C3 cabinet variants?
A: The 00-217-026 is compatible with the standard KR C2 and KR C3 cabinet configurations. However, KR C2 cabinets produced across different revision levels may have minor wiring differences at the power supply connector. We recommend confirming the cabinet revision and wiring diagram before installation. Our technical team can assist with cross-referencing your cabinet serial number.

Q: What pre-shipment testing is performed on each unit?
A: Every KUKA 00-217-026 unit shipped by NINERMAS is bench-tested for output voltage accuracy on all DC rails (24V, ±15V, 5V), thermal stability under load, and connector integrity. A test report is included with each shipment. All units are covered by a 12-month warranty from the date of delivery.

Q: Do I need to update the robot program or reconfigure I/O after replacing the power supply?
A: For a like-for-like 00-217-026 replacement within the same KR C2 or KR C3 cabinet, no program changes or I/O reconfiguration are required. The robot program, tool data, and base coordinates stored on the controller PC are unaffected by the power supply replacement, provided the controller PC and CCU board remain powered or the program has been backed up prior to the maintenance window.

Q: What is the typical lead time and stock availability?
A: NINERMAS maintains in-stock inventory of the KUKA 00-217-026 for immediate dispatch. Standard international shipping lead times apply depending on destination.
