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.

Name CPU fault
Description Stops the inverter output if the communication fault of the built-in CPU occurs.
Check point
앫
Check for devices producing excess electrical noises around the inverter.
앫
Check if the terminal PC is shorted with the terminal SD. (E. 6/E. 7)
Corrective action
앫
Take measures against noises if there are devices producing excess electrical noises around
the inverter.

Inrush overheat
Name Inrush current limit circuit fault
Description
Stops the inverter output when the resistor of inrush current limit circuit overheated. The inrush
current limit circuit fault.
Check point Check that frequent power ON/OFF is not repeated.
Corrective action

Fault 14
Analog in error
Name Analog input fault
Description
Appears if voltage (current) is input to terminal 4 when the setting in Pr. 267 "Terminal 4 input
selection" and the setting of voltage/current input switch are different.
Check point Check the setting of Pr. 267 "Terminal 4 input selection" and voltage/current input switch.
Corrective action
Either give a frequency command by current input or set Pr. 267 Terminal 4 input selection, and
voltage/current input switch to voltage input. (Refer to section 6.16.1.)
