Cause : Parameter storage device fault (control circuit board) comes when the converter output is shut off if a fault occurs in the parameters stored. (EEPROM failure).

  1. Check for too many number of parameter write times.
  2. Set "1" in Pr.342 (write to RAM) for the operation which requires frequent parameter writing via communication, etc. Note that writing to RAM goes back to the initial status at power OFF.
