KUKA KPC400-357-986 – Servo Drive Module | KR C4 Controller Platform
Engineering Background
The KPC400-357-986 is a factory-original servo drive module manufactured by KUKA Roboter GmbH, Germany. Carrying the alternate part reference 00-271-601, this unit is a core power electronics component within the KUKA KR C4 controller architecture — the industry-standard control platform deployed across KUKA KR 6, KR 10, KR 16, KR 30, and KR 60 robot families in high-cycle industrial environments.
Product Positioning
Designed for procurement engineers and maintenance teams requiring a verified OEM replacement or spare for KR C4-based robotic cells. Konmask.com sources this module through authorized industrial channels, with full traceability documentation available upon request. Suitable for both emergency breakdown replacement and planned preventive maintenance stock.

Proven Application Environments
- Automotive Body-in-White (BIW) — spot welding and material handling cells using KUKA KR 16 / KR 30
- Electronics Assembly — precision pick-and-place with KR AGILUS series
- Palletizing & Logistics — high-throughput end-of-line automation with KR QUANTEC
- Machine Tending — CNC loading/unloading with KR 6 R700 and KR 10 R1100
- Foundry & Heavy Industry — harsh-environment deployments requiring robust drive electronics
- Collaborative Cells — integrated KR C4 compact controller configurations
Engineering Advantages
- OEM Authenticity — factory-manufactured by KUKA; eliminates compatibility risk from aftermarket alternatives
- KR C4 Native Integration — plug-and-play replacement; no firmware re-flashing or parameter reconfiguration required in standard swap scenarios
- Proven MTBF — KUKA KPC400-series modules are rated for continuous high-cycle industrial duty
- Compact Form Factor — 420 g module weight minimizes controller cabinet load during multi-axis configurations
- Dual Reference Traceability — cross-referenced under both KPC400-357-986 and 00-271-601 for unambiguous procurement documentation
System Architecture & Signal Flow
Within the KR C4 controller, the KPC400 servo drive module interfaces between the central controller bus (KCB — KUKA Controller Bus) and the axis-specific power stage. The signal flow is:
- KR C4 Cabinet → KCB digital command signals → KPC400-357-986
- KPC400 conditions and amplifies drive signals → Servo Motor (KMC/KSP axis)
- Encoder feedback loop returns position/velocity data → KPC400 → KCB → KUKA KRC4 CPU
This closed-loop architecture ensures sub-millisecond position correction cycles, critical for path accuracy in welding and assembly applications.

Technical FAQ
Q: Is KPC400-357-986 compatible with KR C4 compact controllers?
A: Yes. The KPC400 module series is used across both standard KR C4 and KR C4 compact variants. Confirm your cabinet revision with our team if uncertain.
Q: What is the difference between KPC400-357-986 and 00-271-601?
A: These are the same physical part. KPC400-357-986 is the KUKA engineering part number; 00-271-601 is the KUKA spare parts catalog reference used in service documentation and SAP procurement systems.
Q: Can this module be repaired rather than replaced?
A: Board-level repair is possible for some failure modes. Contact us with fault codes from KUKA SmartPAD for a repair-vs-replace recommendation.
Q: Do you provide installation support?
A: Yes. We provide the KUKA KSS-compatible swap checklist and can connect you with certified KUKA system integrators in your region.
Q: What warranty is included?
A: Konmask provides a 12-month warranty covering manufacturing defects and functional failure under normal operating conditions.
