The KUKA KRC2 (including KRC2 Edition 2005) remains one of the most successful robot controllers in automotive and heavy manufacturing. Due to its PC-based architecture, maintaining a KRC2 requires a mix of specialized robotics hardware and specific industrial computing components.
This KRC2 Spare Parts Index helps engineers identify the correct KCP2 pendants, KSD drives, and MFC/CI3 boards required to keep these legacy systems running at peak performance.
1. KRC2 System Identification
KRC2 controllers are typically paired with KUKA KR series robots (e.g., KR 16, KR 60, KR 150/210).
KRC2 Standard
- Original cabinet PC architecture
- Early internal wiring and motherboard platform
KRC2 Edition 2005 (Ed05)
- Updated industrial PC chassis
- Revised wiring layout and improved reliability
- Some boards (for example CI3 variants) are generation-specific
Core Control Technology
- PC-based real-time motion control
- MFC (Multi-Function Card) handling timing-critical tasks
- DSE-IBS communication for servo coordination
Correctly identifying the exact KRC2 generation is the first step in selecting compatible spare parts.
2. KCP2 Teach Pendant & Cables (HMI)
The KCP2 (KUKA Control Panel) is the primary interface for KRC2. Because it is often dropped or damaged in harsh environments, it is a high-demand spare part.
| Component Name | Part Number / Type | Description |
|---|---|---|
| KCP2 Teach Pendant | 00-110-185 / 00-130-547 | The standard handheld unit for KRC2. |
| KCP2 Connection Cable | 00-108-849 (10m) | High-flex cable connecting KCP2 to the cabinet. |
| KCP2 Membrane/Keypad | Repair Kit | Replacement foil for worn buttons. |
| LCD Display Module | Replacement Panel | 8.4" VGA screen for KCP2. |
3. Drive System: KSD Modules & KPS
KUKA Real-time Servo Drives (KSD) are modular units that control each robot axis.
- KSD1 Series: KSD1-08, KSD1-16, KSD1-32, KSD1-48 (Amperage varies by axis size).
- KPS 600 Power Supply: 00-105-247 (The central power unit that feeds the KSD drives).
- Brake Filter / Resistor: Essential for managing energy during emergency stops.

4. Internal PC & Control Boards
Since KRC2 is PC-based, these "internal" boards are critical for system booting and communication.
- MFC / MFC2 Card: The Multi-Function Card that handles real-time tasks.
- CI3 / CI3 Extended Board: Manages safety signals and peripheral I/O.
- DSE-IBS Card: Digital Servo Electronics card (often piggybacked on the MFC).
- KVGA Card: The graphics card responsible for the KCP2 display output.
- KRC2 Motherboard: Specialized industrial motherboards (e.g., SY-7VBA, Fujitsu-Siemens D15xx).
5. KRC2 Maintenance & Troubleshooting FAQ
Q: My KRC2 loses its position after a power-down. What is wrong?
A: This is almost always caused by failed Lead-Acid Batteries (12V 12Ah x2). When these batteries fail, the PC cannot perform a proper "shutdown" to save the axis encoders. Replace them every 2 years.
Q: What is the difference between KRC2 Standard and Ed05?
A: The Edition 2005 (Ed05) features a more modern PC architecture, a different motherboard, and revised internal wiring for better reliability. Many boards (like the CI3) are specific to the Ed05 version.
Q: Can I replace just the joystick on my KCP2?
A: Yes. The 6D mouse (joystick) is a modular component. Replacing the joystick assembly is a cost-effective alternative to buying a complete new KCP2.
6. Sourcing Hard-to-Find KRC2 Spares
With the KRC2 being a legacy system, KUKA has phased out many new parts. At inrobots.shop, we specialize in keeping KRC2 systems alive:
- Tested & Cleaned PC Racks: Full industrial PC assemblies ready for plug-and-play.
- KSD Drive Exchanges: Reliable modules to replace burnt-out axis drives.
- Hard Drive Imaging: Pre-configured HDDs/SSDs with basic software setups to recover from disk failure.
