Operation Panel
rE1
Indication
Name
Parameter read error
Description
An error occurred in the EEPROM on the operation panel side during parameter copy reading.
Check point
Make parameter copy again. (Refer to page 321.)
Corrective action
Check for an operation panel (FR-DU07) failure. Please contact your sales representative.
Operation Panel
rE2
Indication
Name
Parameter write error
You attempted to perform parameter copy write during operation.
Description
An error occurred in the EEPROM on the operation panel side during parameter copy writing.
Check point
Is the FWD or REV LED of the operation panel (FR-DU07) lit or flickering?
After stopping operation, make parameter copy again. (Refer to page 321.)
Corrective action
Check for an operation panel (FR-DU07) failure. Please contact your sales representative.
Operation Panel
rE3
Indication
Name
Parameter verification error
Data on the operation panel side and inverter side are different.
Description
An error occurred in the EEPROM on the operation panel side during parameter verification.
Check point
Check for the parameter setting of the source inverter and inverter to be verified.
Press
Corrective action
Make parameter verification again. (Refer to page 322.)
Check for an operation panel (FR-DU07) failure. Please contact your sales representative.
Operation Panel
rE4
Indication
Name
Model error
A different model was used for parameter write and verification during parameter copy.
Description
When parameter copy write is stopped after parameter copy read is stopped
Check that the verified inverter is the same model.
Check that the power is not turned OFF or an operation panel is not disconnected, etc. during
Check point
parameter copy read.
Use the same model (FR-F700 series) for parameter copy and verification.
Corrective action
Perform parameter copy read again.
Operation Panel
Err.
Indication
The RES signal is ON
PU and inverter cannot make normal communication (contact fault of the connector)
Description
When the voltage drops in the inverter's input side.
When the control circuit power (R1/L11, S1/L21) and the main circuit power(R/L1, S/L2, T/L3) are
connected to a separate power, it may appear at turning ON of the main circuit. It is not a fault.
Turn OFF the RES signal.
Check the connection of PU and inverter.
Corrective action
Check the voltage on the inverter's input side.
