6.3 The list of fault displays
If the displayed message does not correspond to any of the
following or if you have any other problem, please contact
your sales representative.
 Error message
• A message regarding operational fault and setting fault
by the operation panel and the parameter unit is
displayed. The inverter does not trip.
 Warning
• The inverter does not trip even when a warning is
displayed. However, failure to take appropriate measures
will lead to a fault.
 Alarm
• The inverter does not trip. An Alarm (LF) signal can also
be output with a parameter setting.
 Fault
• A protective function trips the inverter and outputs a Fault
(ALM) signal.
• The data code is used for checking the fault detail via
communication or with Pr.997 Fault initiation.
