Operation panel
E.AIE
indication
Name
Analog input fault
Appears if voltage(current) is input to terminal 4 when the setting in Pr.267 Terminal 4 input selection and the setting of
Description
voltage/current input switch are different.
Check point
Check the setting of Pr. 267 Terminal 4 input selection and voltage/current input switch. (Refer to page 183)
Either give a frequency command by current input or set Pr. 267 Terminal 4 input selection, and voltage/current input
Corrective action
switch to voltage input.
Operation panel
E.OS
indication
Name
Overspeed occurrence
Stops the inverter outputs when the motor speed exceeds the Pr.374 Overspeed detection level under IPM motor
Description
control. This protective function is available while the IPM motor control is selected.
Check point
 Check that the Pr.374 Overspeed detection level value is correct.
Corrective action
 Set the Pr.374 Overspeed detection level value correctly.
Operation panel
E.PID
indication
Name
PID signal fault
If any of PID upper limit (FUP), PID lower limit (FDN), and PID deviation limit (Y48) turns ON during PID control,
inverter shuts off the output. This function is active under the following parameter settings: Pr.554 PID signal operation
selection  "0 or 10", Pr.131 PID upper limit  "9999", Pr.132 PID lower limit  "9999", and Pr.553 PID deviation limit 
Description
"9999". This protective function is not active in the initial setting (Pr.554 = "0", Pr.131 = "9999", Pr.132 = "9999", Pr.553
= "9999").
 Check if the measured PID value is greater than the upper limit (Pr.131) or smaller than the lower limit (Pr.132).
Check point
Check if the absolute PID deviation value is greater than the limit value (Pr.553).
Corrective action
Make correct settings for Pr.131 PID upper limit, Pr.132 PID lower limit, Pr.553 PID deviation limit.
Operation panel
E.SAF
indication
Name
Safety circuit fault
 Appears when internal circuits are malfunctioning.
Description
 Appears when one of the lines between S1 and SC, or between S2 and SC is opened.
Check point
Check if the shorting wire across the terminals S1 and SC or the terminals S2 and SC is disconnected.
Corrective action
Short across the terminals S1 and SC and the terminals S2 and SC with shortening wires.
NOTE
 If protective functions of E.ILF, E.SOT, E.AIE, E.IOH, E.PTC, E.CDO, E.PID and E.SAF are activated when using the FR-
PU04, "Fault 14" is displayed.
Also when the faults history is checked on the FR-PU04, the display is "E.14".
 If faults other than the above appear, contact your sales representative.
