E. 1 to

Option alarm
Stops the inverter output if a contact fault or the like of the connector between the inverter and
communication option occurs.
Check that the communication option is plugged into the connector securely.
(1 to 3 indicate the option slot numbers.)
• Connect the plug-in option securely.
• Please contact your sales representative.
E.11
Reversing deceleration alarm
If the speed command and estimated speed direction differ when the rotation direction changes
from forward to reverse rotation or reverse to forward rotation during vector control without
encoder, the motor runs at low speed and stops decelerating. Since the rotation direction will not
change to the opposite direction causing overload, the inverter stops output
Check for an excessive error between R1 of the motor and R1 of the inverter.
• Perform offline auto tuning or start time tuning.
• Please contact your sales representative.
E.PE
Parameter storage device alarm
Appears when an error occurred in the stored parameters. (E
Check for too many number of parameter write times.
• Please contact your sales representative.
• When performing parameter write frequently for communication purposes, set "1" in Pr. 342 to
enable RAM write. Note that powering off returns the inverter to the status before RAM write.
E.PUE
PU disconnection
This function stops the inverter output if communication between the inverter and PU is suspended,
e.g. the operation panel or parameter unit is disconnected, when "2", "3", "16" or "17" was set in Pr.
75 "reset selection/disconnected PU detection/PU stop selection". This function stops the inverter
output if the number of successive communication errors is greater than the permissible number of
retries when the Pr. 121 value is other than "9999" for RS-485 communication from the PU
connector. This function also stops the inverter output if communication is broken for the period of
time set in Pr. 122.
• Check for loose fitting of the FR-DU04-
• Check the Pr. 75 setting.

Fit the FR-DU04- or FR-PU04V 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.
