Set value= 24 H0 1 0 0NO-contact inputAlways detected.Coasting to a stopExternal fault 5 is input from terminal 5The inverter operates differently as described below when Experiencing major faultsor minor faults. The digits in the error display Ext. Fault 5 to 8 (EF5 to EF8) indicate theterminal numbers in which external faults 5 to 8 are set.Major faultsIf an external fault is input, the fault is displayed and the inverter stops according toprocess selection at external fault detection. Fault contact output relay is outputimmediately.Minor faultsFault display blinks only when external fault is input (the display is made for 0.5 secondeven when input is less than 0.5 second). External faults 5 to 8 are set to multi-function terminals 1 to 4 (Nos. ofterminal 5 to 8)No. of FaultMulti-functionTerminal(Major Fault)Display of Digital Operator(Minor Fault) BlinkingExternal Fault 5 Terminal 5 Ext.
