List of fault displays

For details, refer to the FR-A800 Instruction Manual (Detailed).
 Error message
• A message regarding operational fault and setting fault
by the operation panel and the parameter unit is
displayed. The inverter output is not shut off.

 Warning
• The inverter output is not shut off even when a warning is
displayed. However, failure to take appropriate measures
will lead to a fault.
