Infeed: Line supply undervoltage alarm

What does 206105 mean?

An alarm indicating that the filtered, steady-state value of the line supply voltage has dropped below the alarm threshold set by p0282. This is a warning condition, not a shutdown, meaning there is no immediate reaction. The alarm value (r2124) shows the current line supply voltage.

Complete Troubleshooting Guide

1. 1

   Check the incoming line supply for any transient voltage sags or sustained undervoltage conditions.

2. 2

   Verify that the line supply voltage parameter (p0210) is correctly configured to match the connected power supply.

3. 3

   Review and adjust the line supply undervoltage alarm threshold (p0282) if the current setting is too sensitive or does not align with operational requirements.
