Infeed: Line Supply Undervoltage

What does A06105 mean?

The filtered (steady-state) value of the line supply voltage at the infeed unit has dropped below the configured alarm threshold (p0282 multiplied by p0210). This indicates a potential issue with the incoming power supply, which could lead to operational instability or trigger more severe faults if not resolved promptly.
