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

Was bedeutet 26036 ?

An undervoltage condition has occurred in the intermediate DC circuit during operation. This can be caused by low incoming mains voltage, issues with the intermediate circuit cabling, or a fault in the KPP/KSP charging circuit that prevents proper voltage build-up.

• The intermediate DC circuit voltage in the KPP/KSP drive is too low.
• Main supply voltage is insufficient.
• Faulty power input stage of the KPP/KSP.
• Underload condition or unexpected load characteristic.
• Failure in the DC bus smoothing capacitors.

1. 1

   Review the trace recording of the intermediate circuit voltage for drops below the operational threshold.

2. 2

   Measure the incoming mains voltage to ensure it is within specified limits for the drive system.

3. 3

   Check the intermediate circuit cabling for damage, loose connections, or incorrect sizing that could cause voltage drop.

4. 4

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

5. 5

   Check the KSP module and the KPP charging circuit for faults or proper operation.
