Digital Operator Display Fault NameEF0 Option Card External FaultAn external fault condition is present.Cause Possible SolutionAn external fault was received from the PLCand F6-03 is set to a value other than 3.• Remove the cause of the external fault.• Remove the external fault input from the PLC.Problem with the PLC program Check the PLC program and correct problems.Digital Operator Display Fault NameEF1 External Fault (input terminal S1)External fault at multi-function input terminal S1.EF2 External Fault (input terminal S2)External fault at multi-function input terminal S2.EF3 External Fault (input terminal S3)External fault at multi-function input terminal S3.EF4 External Fault (input terminal S4)External fault at multi-function input terminal S4.EF5 External Fault (input terminal S5)External fault at multi-function input terminal S5.EF6 External Fault (input terminal S6)External fault at multi-function input terminal S6.EF7 External Fault (input terminal S7)External fault at multi-function input terminal S7.EF8 External Fault (input terminal S8)External fault at multi-function input terminal S8.Cause Possible SolutionAn external device tripped an alarm function Remove the cause of the external fault and reset the fault.Wiring is incorrect• Properly connect the signal lines to the terminals assigned for external fault detection(H1-oo = 20 to 2B).• Reconnect the signal line.Multi-function contact input setting isincorrect• Check for unused terminals set for H1-oo = 20 to 2B (External Fault).• Change the terminal settings.Digital Operator Display Fault NameErrEEPROM Write ErrorData cannot be written to the EEPROMCause Possible SolutionNoise has corrupted data while writing to theEEPROM• Press “ENTER” on the digital operator.• Correct the parameter setting.• Cycle power to the drive.• If the problem continues, replace the control board or the entire drive.
