Kuka · KR C4 Controller
What does 26048 mean?
This fault occurs when an overvoltage condition is detected during the charging phase of the KPP/KSP drive. This can be caused by an excessively high mains voltage or an insufficient number of connected capacitors, posing a risk to sensitive components.
Common Causes
- Mains voltage being too high
- Insufficient number of capacitors connected (too few modules) in the system
Repair Steps & Checklist
