E.PE2
Parameter storage device alarm (main circuit board)
A fault occurred in parameters stored (E²PROM failure).

Please contact your sales representative.
E.PUE
PU disconnection
This function stops the inverter output if communication between the inverter and PU is
suspended, e.g. the operation panel and parameter unit is disconnected, when "2", "3",
"16" or "17" was set in Pr. 75 "Reset selection/disconnected PU detection/PU stop selec-
tion". This function stops the inverter output when communication errors occurred consecu-
tively for more than permissible number of retries when a value other than "9999" is set in
Pr. 121 "Number of PU communication retries" during the RS-485 communication with the
PU connector. This function also stops the inverter output if communication is broken for
the period of time set in Pr. 122 "PU communication check time interval".
Check that the FR-DU07 or parameter unit (FR-PU04/FR-PU07) is fitted tightly.
Check the Pr. 75 setting.
Fit the FR-DU07 or parameter unit (FR-PU04/FR-PU07) securely.
E.RET
Retry count excess
If operation cannot be resumed properly within the number of retries set, this function stops
the inverter output.
Find the cause of alarm occurrence.
Eliminate the cause of the error preceding this error indication.
E. 6
E. 7
E.CPU
CPU error
Stops the inverter output if the communication error of the built-in CPU occurs.
Check for devices producing excess electrical noises around the inverter.
Take measures against noises if there are devices producing excess electrical noises
around the inverter.
Please contact your sales representative.
