Parameter write error
Parameter copy from the operation panel to the inverter was attempted during operation.
A failure has occurred at the operation panel side EEPROM while writing the copied
parameters.
A failure has occurred in the USB memory device while writing the copied parameters or PLC
function project data.
Check that the inverter is stopped.
After stopping the operation, perform parameter copy again. (Refer to page 5-702.)
The operation panel (FR-DU08) may be faulty. Please contact your sales representative.
Perform parameter copy or PLC project data copy again.
(Refer to page 5-591 and page 5-704)
The USB memory device may be faulty. Replace the USB memory device.
rE3
Parameter verification error
The data in the inverter are different from the data in the operation panel.
A failure has occurred at the operation panel side EEPROM during parameter verification.
A failure has occurred in the USB memory device during parameter verification.
The data in the inverter are different from the data in the USB memory device or the
personal computer (FR Configurator2)
Check the parameter setting of the source inverter against the setting of the destination
inverter.
Continue the verification by pressing SET key.
Perform parameter verification again. (Refer to page 5-703.)
The operation panel (FR-DU08) may be faulty. Please contact your sales representative.
The USB memory device may be faulty. Replace the USB memory device.
Verify the PLC function project data again. (Refer to page 5-591.)
rE4
Model error
A different model was used when parameter copy from the operation panel or parameter
verification was performed.
The data in the operation panel were not correct when parameter copy from the operation
panel or parameter verification was performed.
Check that the parameter copy or verification source inverter is of the same model.
Check that parameter copy to the operation panel was not interrupted by switching OFF the
power or by disconnecting the operation panel.
Perform parameter copy and parameter verification between inverters of the same model
(FR-A800 series).
Perform parameter copy to the operation panel from the inverter again.
