E.RET
Retry count excess
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.
Find the cause of fault occurrence.
Eliminate the cause of the error preceding this error indication.
E. 5
E. 6
E. 7
E.CPU
CPU fault
Stops the inverter output if the communication fault of the built-in CPU occurs.
Check for devices producing excess electrical noises around the inverter.
Check if the terminal PC is shorted with the terminal SD. (E. 6/E. 7)
Take measures against noises if there are devices producing excess electrical noises around
the inverter.
Check the connection between the terminals PC and SD. (E. 6/E. 7).
Please contact your sales representative.
E.IOH
Inrush current limit circuit fault
Stops the inverter output when the resistor of inrush current limit circuit overheated. The inrush
current limit circuit fault.
Check that frequent power ON/OFF is not repeated.
Configure a circuit where frequent power ON/OFF is not repeated. If the problem still persists
after taking the above measure, please contact your sales representative.
E.AIE
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 voltage/current input switch are different.
Check the setting of Pr. 267 "Terminal 4 input selection" and voltage/current input switch.
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.)
