FR-LU08
OC detect level
Name
Abnormal output current detection
Description
The inverter trips if the output current exceeds the Pr. 150 "Output current detection level"
setting.
This functions is available when Pr. 167 "Output current detection operation selection" is set to
"1". When the initial value (Pr. 167 = "0") is set, this protective function is not available.
Check point
Check the settings of Pr. 150, Pr. 151 "Output current detection signal delay time", Pr. 166 "Output
current detection signal retention time", and Pr. 167. (Refer to page 5-244.)

E.IOH
FR-LU08
Inrush overheat
Name
Inrush current limit circuit fault (Standard models only)
Description
The inverter trips when the resistor of the inrush current limit circuit is overheated. The inrush
current limit circuit failure
Check point
Check that frequent power ON/OFF is not repeated.
Check if the input side fuse (5A) in the power supply circuit of the inrush current limit circuit
contactor (FR-F840-03250(132K) or higher) is blown.
Check that the power supply circuit of inrush current limit circuit contactor is not damaged.
Corrective action
Configure a circuit where frequent power ON/OFF is not repeated.
If the situation does not improve after taking the above measure, please contact your sales
representative.

FR-LU08
VFD Comm error
Name
Communication fault (inverter) (not for FR-F800-E)
Description
The inverter trips when communication error occurs consecutively for the permissible number of
retries or more when Pr. 335 "RS-485 communication retry count"
≠
"9999" during RS-485
communication from the RS-485 terminals. The inverter also trips if communication is broken for
the period of time set in Pr. 336 "RS-485 communication check time interval".
Check point
Check the RS-485 terminal wiring.
Corrective action
Perform wiring of the RS-485 terminals properly.
Operation panel
indication
E.AIE
FR-LU08
Analog input fault
Name
Analog input fault
Description
The inverter trips when a 30 mA or higher current or a 7.5 V or higher voltage is input to terminal
2 while the current input is selected by Pr. 73 "Analog input selection", or to terminal 4 while the
current input is selected by Pr. 267 "Terminal 4 input selection".
Check point
Check the Pr. 73, Pr. 267, and the voltage/current input switch settings.(Refer to page 5-255)
Corrective action
Either give a current less than 30 mA, or set Pr. 73, Pr. 267, and the voltage/current input switch
to the voltage input and input a voltage.
