Set the threshold values

Note

Critical operating states may not be reported under certain circumstances.

If you set the threshold values for warning messages and error messages incorrectly, EPP9022 may not inform you of critical operating states:
overcurrent, overvoltage, undervoltage.

  • Be very careful when changing the threshold values.
  • Enlarge the permissible range only if you have good reasons to do so.

You can set the threshold values for warning messages and error messages via the CoE parameters shown in the following tables. Observe the recommended value range.
