Check the Pr.77 setting. (Refer to
rE1
Parameter read error
• A failure has occurred at EEPROM in the operation panel during reading of the parameter settings for
Parameter copy.
• Perform Parameter copy again. (Refer to
• The operation panel (FR-DU08) may be faulty. Contact your sales representative.
rE2
Parameter write error
• Parameter write from the operation panel to the multifunction regeneration converter was attempted for
Parameter copy during operation.
