26104
IxT overload error, KPP/KSP (axis)
Kuka · KR C4 Controller
What does 26104 mean?
This error indicates an axis overloaded condition, where the mean continuous current is too high. It can occur during start-up due to excessive load in the program or during operation due to system modifications or temperature influences.
Common Causes
- Excessive mechanical load in the program during start-up.
- Modifications to the system increasing axis load during operation.
- Elevated ambient temperature influencing motor/drive performance.
- Program velocity set too high for the current load conditions.
- Insufficient CBS pressure (likely related to braking or counterbalancing).
- Mechanical issues within the gear unit.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Reinitialize the drive bus by performing a Power Off / Power On cycle.
- 2
Check the trace recording of the axis/current to analyze load patterns and peaks.
- 3
Adjust program velocity to reduce the continuous load on the axis.
- 4
Verify CBS pressure is within specified operating limits.
- 5
Inspect the gear unit for wear, damage, or mechanical binding.
