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.

Complete Troubleshooting Guide

1. 1

   Check the incoming line supply voltage at the infeed unit.

2. 2

   Verify the set line supply voltage parameter (p0210) matches the actual system voltage.

3. 3

   Review and adjust the line supply undervoltage alarm threshold parameter (p0282) if necessary and appropriate for the application.
