Fault in brake resistor, KPP/KSP (axis)

What does 26122 mean?

The KPP module has detected an error in the ballast circuit, which typically includes the brake resistor. This indicates an issue with the energy dissipation components, potentially leading to overvoltage conditions if braking energy cannot be properly absorbed.

• Ballast resistor fault.
• Cabling between KPP and ballast resistor is damaged or improperly connected.

Click steps to track your progress.

1. 1

   Inspect the ballast resistor for damage or overheating.

2. 2

   Check cabling between the KPP and the ballast resistor for damage and correct connections.

3. 3

   Reinitialize the drive bus: Power Off / Power On.

4. 4

   Check the KPP module.
