Indication
E.RET
FR-PU04
FR-PU07
Retry No Over
Name
Retry count excess
Description
If operation cannot be resumed properly within the number of retries set, this function trips
the inverter.
Functions only when Pr. 67 "Number of retries at fault occurrence" is set. When the initial
value (Pr. 67 = 0) is set, this protective function does not function.
Check point
Find the cause of fault occurrence.
Corrective action
Eliminate the cause of the error preceding this error indication.

Fault 5
E.CPU
CPU Fault
Name
CPU fault
Description
Stops the inverter output if the communication fault of the built-in CPU occurs.
Check point
Check for devices producing excess electrical noises around the inverter.
Corrective action
Take measures against noises if there are devices producing excess electrical noises
around the inverter.
Please contact your sales representative.

OC detect level
Name
Output current detection value exceeded
Description
This function is activated when the output current exceeds the Pr. 150 "Output current
detection level" setting.
Check point
Check the settings of Pr. 150 "Output current detection level", Pr. 151 "Output current
detection signal delay time", Pr. 166 "Output current detection signal retention time",
Pr. 167 "Output current detection operation selection". (Refer to 6.9.7).

The inrush current limit circuit fault.
Check point
Check that frequent power ON/OFF is not repeated.
Corrective action
Configure a circuit where frequent power ON/OFF is not repeated. If the problem still per-
sists after taking the above measure, please contact your sales representative.
