Warning List - Omron ACCURAX G5 User Manual

11-2 Warning List

This is a function to output a warning signal before the protective function operates to notify the overload and other statuses in advance.
Set the warning output type to Warning Output Selection 1 (Pn440) and Waning Output Selection 2 (Pn441).
Precautions for Correct Use
Each warning automatically returns to the status before it occurred once the system recovers from the error.
However, for the time set in the Warning Latch Hold Time Selection (Pn627), the warning status will be held.
To clear the warning during the latch hold time, do so by performing the same procedures as alarm clear.
