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

What does 26108 mean?

This fault indicates an undervoltage condition in the intermediate DC link circuit during operation. This usually points to issues with the incoming power supply or the drive's charging circuit. Persistent undervoltage can lead to unreliable drive operation and potential damage if the drive attempts to operate outside its specified voltage range.

• Mains voltage dropping below the permissible input range for the drive.
• Faulty intermediate circuit cabling.
• Malfunction in the KPP/KSP charging circuit.

Click steps to track your progress.

1. 1

   Check trace recording of the intermediate circuit voltage.

2. 2

   Check mains voltage at the input to the drive.

3. 3

   Check intermediate circuit cabling for loose connections or damage.

4. 4

   Reinitialize the drive bus: Power Off / Power On.

5. 5

   Check KSP module for faults.

6. 6

   Check KPP module for faults.
