Overcurrent, KPP/KSP (axis)

What does 26034 mean?

A fault that briefly results in an overcurrent exceeding the maximum current of the KUKA KRC4 KPP. This is typically caused by a sudden short-circuit or an instantaneous heavy load.

• Short circuit in the motor windings or motor cable.
• Sudden heavy mechanical load or obstruction, causing an instantaneous current surge.
• Incorrect motor or drive parameters that allow excessive current draw.

Click steps to track your progress.

1. 1

   Check the trace recording of the axis/current to identify the specific event that triggered the overcurrent.

2. 2

   Inspect the motor and motor cable for any signs of short circuits, insulation damage, or mechanical damage.

3. 3

   Test motor windings and power cables for short circuits or ground faults using appropriate continuity and insulation tests.

4. 4

   Reinitialize the drive bus by performing a Power Off / Power On cycle for the KUKA KRC4 controller.

5. 5

   Check the KUKA KRC4 KSP and KPP modules for any internal fault indicators or parameter settings.
