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. 1

    Reinitialize the drive bus by performing a Power Off / Power On cycle.

  2. 2

    Check the trace recording of the axis/current to analyze load patterns and peaks.

  3. 3

    Adjust program velocity to reduce the continuous load on the axis.

  4. 4

    Verify CBS pressure is within specified operating limits.

  5. 5

    Inspect the gear unit for wear, damage, or mechanical binding.
