Product Details And Specifications

KUKA 00-284-170 KPC4 Control Board – Obsolete KPC4 Series Spare Part

When the KPC4 control board on your KUKA robot fails, the clock starts ticking. This module is the processing core of the KPC4 controller cabinet — the unit that governs motion coordination, I/O communication, and real-time program execution across the robot cell. KUKA discontinued the KPC4 series, and replacement units are no longer available through official distribution channels.

Technical Specifications

Note: Electrical parameters such as supply voltage, bus interface specifications, and firmware revision are board-revision dependent. DriveKNMS will confirm exact revision details upon inquiry. No parameters are assumed or fabricated.

Solving the Discontinued Hardware Crisis

The KUKA KPC4 controller was widely deployed in automotive body shops, foundry automation, and general-purpose robotic cells throughout the 1990s and early 2000s. Many of these installations remain in productive service today — not because the robots are obsolete, but because the mechanical and kinematic performance of a KUKA KR series arm has a service life that far exceeds the availability of its electronic components.

The KPC4 control board is the single most failure-prone component in the KPC4 cabinet. It handles the real-time operating system, axis interpolation, and fieldbus communication. When it fails, no other component substitution restores function. There is no cross-compatible modern replacement that installs without a full controller migration project.

Plant managers who have maintained a spare 00-284-170 board on the shelf have consistently avoided the forced upgrade decision. Those who have not faced a binary choice: source the board on the secondary market or commit to a six-figure capital project. DriveKNMS operates specifically in this secondary market, with sourcing networks across decommissioned automotive plants and certified refurbishment partners.

Condition & Reliability Assurance

Sourcing a discontinued control board from the secondary market carries legitimate risk. DriveKNMS applies a structured 5-step qualification process to every KPC4 board before it is offered for sale:

1. Visual and mechanical inspection. Board surface, connector pins, solder joints, and PCB traces are examined under magnification. Units with physical damage, corrosion, or burn marks are rejected at this stage.
2. Electrolytic capacitor assessment. Capacitors are tested for ESR (equivalent series resistance) and capacitance retention. Boards with degraded capacitors are either recapped by certified technicians or rejected.
3. Firmware version verification. The firmware revision on each board is read and documented. Customers are informed of the exact revision prior to shipment so compatibility with their KSS version can be confirmed.
4. Pin and connector integrity check. All edge connectors and board-to-board connectors are inspected for oxidation, pin deformation, and contact resistance. Affected contacts are cleaned or the unit is rejected.
5. Functional power-on test (where test fixture is available). Boards are powered in a controlled bench environment to verify basic initialization and communication response before dispatch.

Key Features for System Maintenance

• Drop-in replacement. The 00-284-170 KPC4 board installs into the existing KPC4 cabinet without mechanical modification. No new cabinet, no new cable harness.
• No reprogramming of robot logic required. Robot programs, tool data, and base data reside on the KRC hard drive or backup media — not on the control board itself. Swapping the board does not erase application software.
• Avoids engineering re-integration costs. A full KRC2-to-KRC4 migration requires mechanical re-mounting, new cable sets, updated safety circuits, and re-certification of the cell. Replacing the KPC4 board requires none of this.
• Preserves existing operator training investment. Your operators know the KRC1/KRC2 teach pendant. A board replacement keeps the interface identical. A controller migration forces retraining.
• Supports long-term spare parts strategy. DriveKNMS can advise on additional KPC4-series components — power supply units, DSE boards, MFC boards — to build a comprehensive cold-spare inventory for your KUKA fleet.

Q: How do I confirm the board is new or professionally refurbished — not a field-pulled unit sold as-is?
A: Every unit shipped by DriveKNMS is accompanied by a condition report documenting the qualification steps completed, the firmware revision identified, and the test results recorded. We do not sell untested field-pull units without explicit disclosure.

Q: Can DriveKNMS source other KPC4-series components?
A: Yes. Contact us with your full bill of materials for the KPC4 cabinet. We will advise on availability across our sourcing network.
