Please contact your sales representative.· Return the switch for the manufacturer setting of the plug-in option to the initial status. (Refer toinstruction manual of each option)FR-PU04E.OP1Option 1 FaultFR-PU07Communication option faultStops the inverter output when a communication line error occurs in the communication option.· Check for a wrong option function setting and operation.· Check that the plug-in option is plugged into the connector securely.· Check for a brake in the communication cable.· Check that the terminating resistor is fitted properly.· Check the option function setting, etc.· Connect the plug-in option securely.· Check the connection of communication cable.FR-PU04E. 1Fault 1FR-PU07Option faultStops the inverter output if a contact fault or the like of the connector between the inverter andcommunication option occurs.Appears when the switch for the manufacturer setting of the plug-in option is changed.1. Check that the plug-in option is plugged into the connector securely.2. Check for excess electrical noises around the inverter.1. Connect the plug-in option securely.2. Take measures against noises if there are devices producing excess electrical noises around the inverter.If the problem still persists after taking the above measure, please contact your sales representativeor distributor.3. Return the switch position for the manufacturer setting of the plug-in option to the initial status.

When the initial value (Pr. 67 = "0")is set, this fault does not occur.Find the cause of alarm occurrence.Eliminate the cause of the error preceding this error indication.Operation PanelIndicationNameDescriptionCheck pointCorrective actionOperation PanelIndicationNameDescriptionCheck pointCorrective actionOperation PanelIndicationNameDescriptionCheck pointCorrective actionE. 6Fault 6E. 7FR-PU04FR-PU07Fault 7E.CPUCPU FaultCPU errorStops the inverter output if the communication error of the built-in CPU occurs.Check for devices producing excess electrical noises around the inverter.· Take measures against noises if there are devices producing excess electrical noises around theinverter.· Please contact your sales representative.FR-PU04 ————E.CTEFR-PU07 E.CTEOperation panel power supply short circuit, RS-485 terminal power supply short circuitWhen the operation panel power supply (PU connector) is shorted, this function shuts off the poweroutput. At this time, the operation panel (parameter unit) cannot be used and RS-485 communicationfrom the PU connector cannot be made. When the internal power supply for the RS-485 terminals areshorted, this function shuts off the power output.At this time, communication from the RS-485 terminals cannot be made.To reset, enter the RES signal or switch power off, then on again.1. Check for a short circuit in the PU connector cable.2. Check that the RS-485 terminals are connected correctly.1. Check the PU and cable.2. Check the connection of the RS-485 terminalsFR-PU04E.P24E.P24FR-PU0724VDC power output short circuitWhen the 24VDC power output from the PC terminal is shorted, this function shuts off the power output.At this time, all external contact inputs switch off. The inverter cannot be reset by entering the RESsignal. To reset it, use the operation panel or switch power off, then on again.· Check for a short circuit in the PC terminal output.· Remedy the earth (ground) fault portion.102
