Ground fault, KPP/KSP (axis)

What does 26033 mean?

An overcurrent condition has occurred in the power unit, specifically indicating a ground fault. This suggests an insulation breakdown or a short circuit to ground within the motor or its associated cabling, posing a safety risk.

• Ground fault detected on the KPP/KSP drive or motor.
• Leakage current from a power conductor to ground.
• Insulation failure in motor windings or power cables.
• Faulty KPP/KSP internal shielding.
• Incorrect grounding connection.

Click steps to track your progress.

1. 1

   Check the motor cable for physical damage, shorts to ground, or insulation breakdown using an insulation tester (megger).

2. 2

   Check the motor for internal ground faults or winding damage by measuring winding resistance and insulation resistance.

3. 3

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

4. 4

   Check the KSP module for diagnostic indicators related to power unit status.

5. 5

   Check the KPP module for diagnostic indicators related to power unit status.
