Warning Messages

Warnings are user notifications displayed through flashing messages on the display/keypad. They are not alarms or protections and are not recorded in the Alarm History. Some messages are temporary user interface indications, while most are coded warnings starting with a letter 'W' followed by two digits indicating the active warning.

Coded Warning List

  • W03 SEARCHING...: The user interface is searching for the next page data to display.
  • W06 HOME SAVED: The current page has been saved as the home page for the next inverter power-up.
  • W07 DOWNLOADING: The display/keypad is writing saved WORK area parameters to the inverter.
  • W08 UPLOADING: The display/keypad is reading WORK area parameters from the inverter to save.
  • W09 DOWNLOAD OK: The display/keypad has successfully completed writing parameters to the inverter.
  • W10 DOWNLOAD KO: The display/keypad has interrupted parameter writing; download procedure failed.
  • W11 UPLOAD OK: The display/keypad has successfully completed reading parameters from the inverter.
  • W12 UPLOAD KO: The display/keypad has interrupted parameter reading; upload procedure failed.
  • W13 NO DOWNLOAD: A download procedure was requested, but no parameters were saved on the display/keypad.
  • W16 PLEASE WAIT: Wait for the requested operation to complete.
  • W18 PARAMS LOST: Parameter writing was interrupted; the inverter contains inconsistent parameters. Restart or repeat the download needed.
  • W19 NO PARS LOAD: Unable to perform UPLOAD procedure.
  • W20 NON ORA: The requested operation cannot be performed at this time.
  • W21 CONTROL ON: Operation is prevented because the inverter is running; QUADRO ENABLE SELECTOR active.
