Mains phase failure, KPP/KSP (axis)

What does 26118 mean?

A failure has been detected in one or more mains input phases supplying the KPP or KSP device for a specific axis. This indicates an issue with the incoming AC power supply to the drive, such as a blown fuse, tripped breaker, or open phase. Loss of a mains phase can cause imbalances, overheating, and prevent the drive from operating.

1. 1

   Inspect the power lead connecting to the KPP for damage, loose connections, or incorrect phasing.

2. 2

   Inspect all KPP cabling, including input power terminals, for secure connections and integrity.

3. 3

   Perform a Power Off / Power On cycle of the entire system to reinitialize the drive bus.

4. 4

   Check the status indicators or diagnostics of the KPP device.
