Auto operation is activated by the multi-functioninput terminals set to [SEQ-L], [SEQ-M], [SEQ-H] and[Go step] in I/O-12 ~ I/O-14.I/O► Seq select51 351Factory Default: 1 101StepFrequencyParameterCodeSpeed-H(P3)Speed-M(P2)Speed-L(P1)Sequence 1 0 0 1Sequence 2 0 1 0I/O-50 ~Sequence 3 1 0 0I/O-84Sequence 4 0 1 1Sequence 50: OFF, 1: ONOutput FrequencySeq1 / 2FSeq1 / 1F1D(Forward)2D(Forward)1 0 1This code selects the sequence to set frequency,transient time, steady speed time and motor direction thesteps.I/O► Step number52 2 522Seq1 / 3F3D(Reverse)1T 1S 2T 2S 3T 3STimeFactory Default: 2 2This code sets the number of steps to use for thesequence number selected in I/O-51.P1-CM‘SEQ-L’ON[Example 1 of ‘Auto-A’ operation]Time[Auto-A]This mode will allow the inverter to operate automaticallyfollowed by its pre-programmed sequence. According tothis sequence, eight different steps of Frequency,Transient Time, Steady Speed time and Motor Directioncan be initiated with only a single multi-function inputcontact closure (I/O-12 ~ I/O-14). The sequence andsteps are set in I/O-51 ~ I/O-84.Output FrequencySequence 1 Sequence 3 Sequence 2SEQ1 / 2FSEQ2 / 2FSEQ1 / 1FSEQ3 / 2FTimeSEQ3 / 1FP1-CM‘SEQ-L’ONTimeP2-CM‘SEQ-M’ONTime[Example 2 of ‘Auto-A’ operation]134
