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

¿Qué significa 26108 ?

This fault indicates that the DC link voltage in the intermediate circuit has dropped below its minimum operating threshold during operation. This is typically caused by insufficient incoming mains supply, issues with the DC link cabling, or a problem with the internal charging circuit.

• Mains voltage supplied to the drive dropping below the minimum required level.
• Loose, damaged, or undersized intermediate circuit cabling.
• Malfunction or failure of the internal intermediate circuit charging components.

1. 1

   Analyze the trace recording of the intermediate circuit voltage to observe voltage sags.

2. 2

   Measure the incoming mains voltage at the drive input terminals.

3. 3

   Inspect the intermediate circuit cabling for proper connections, integrity, and specified gauge.

4. 4

   Check the intermediate circuit charging circuit components (e.g., pre-charge resistors, contactors) for proper operation.

5. 5

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