Intermediate circuit voltage too low, KPP/KSP (axis)

What does 26036 mean?

An undervoltage condition in the intermediate circuit of the KUKA KRC4 KPP/KSP during operation. This indicates insufficient power supply to the DC link or an issue with its charging circuit, preventing the drive from maintaining adequate operating voltage.

• Low incoming mains voltage or significant voltage sag under load.
• Faulty or improperly connected intermediate circuit cabling, causing resistance or poor contact.
• Problem with the KUKA KRC4 KPP/KSP charging circuit components.

Click steps to track your progress.

1. 1

   Check the trace recording of the intermediate circuit voltage to analyze the undervoltage event and its timing.

2. 2

   Measure the incoming mains voltage to ensure it is stable and within specified operating limits for the KUKA KRC4 system.

3. 3

   Inspect the intermediate circuit cabling for proper connections, continuity, absence of damage, and secure terminals.

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 charging circuit components and connections for defects.
