Ground fault, KPP/KSP (axis)

Hva betyr 26105 ?

This fault indicates a power unit overcurrent condition specifically due to a ground fault on an axis. It points to an insulation breakdown or unintended conductive path to ground in the motor or its cabling, leading to excessive current flow.

• Insulation breakdown or damage in the motor cable, causing a short to ground.
• Internal ground fault within the motor windings or housing.
• Damaged components within the KPP or KSP causing a ground path.

1. 1

   Visually inspect the motor cable for insulation damage or signs of arcing.

2. 2

   Measure insulation resistance of the motor cable between phases and to ground using a megger.

3. 3

   Measure insulation resistance of the motor windings to ground.

4. 4

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

5. 5

   Inspect KSP (KUKA SmartPAD) and KPP (KUKA Power Pack) for signs of damage or loose connections.
