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

What does 26035 mean?

An overvoltage condition has occurred in the intermediate DC circuit during operation. This can be caused by high incoming mains voltage, a fault in the ballast switch, or excessive braking energy being fed back into the DC bus.

• The intermediate DC circuit voltage in the KPP/KSP drive is too high.
• Regenerative braking is generating excessive voltage.
• Fault in the DC bus voltage control or regulation circuit.
• Power supply voltage is higher than expected.
• Overvoltage protection tripped.

Click steps to track your progress.

1. 1

   Review the trace recording of the intermediate circuit voltage for transient or sustained overvoltage spikes.

2. 2

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

3. 3

   Check the ballast switch for proper operation and functionality, ensuring it can dissipate excess energy.

4. 4

   If excessive load during braking is identified, review and reduce the braking energy or frequency in the application program.

5. 5

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

6. 6

   Check the KSP module and KPP module for diagnostic indicators related to DC bus voltage.
