PROTECTIVE FUNCTIONS
Er8
USB memory device operation error
• An operation command was given during the USB memory device operation.
• A copy operation (writing) was performed while the PLC function was in the RUN state.
• A copy operation was attempted for a password locked project.
• Check if the USB memory device is operating.
• Check if the PLC function is in the RUN state.
• Check if the project data is locked with a password.
• Perform the operation after the USB memory device operation is completed.
• Stop the PLC function. (Refer to
• Unlock the password of the project data using FR Configurator2. (Refer to the Instruction Manuals of FR
Configurator2 and GX Works2.)
rE1
Parameter read error
• A failure has occurred at the operation panel side EEPROM while reading the copied parameters.
• A failure has occurred in the USB memory device while copying the parameters or reading the PLC function
project data.
• Perform parameter copy again. (Refer to
• Perform PLC function project data copy again.(Refer to
• The USB memory device may be faulty. Replace the USB memory device.
• The operation panel (FR-DU08) may be faulty. Please contact your sales representative.
rE2
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
• The operation panel (FR-DU08) may be faulty. Please contact your sales representative.
• Perform parameter copy or PLC project data copy again. (Refer to
• 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
Perform parameter verification again. (Refer to
• 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 433 and the PLC function programming manual.)
