Auto mode
50
None
Factory Default:
None
There are two modes of ' Auto-A' and ' Auto-B' in Auto
mode. Auto operation is activated by the multi-function
input terminals set to [SEQ-L], [SEQ-M], [SEQ-H] and
[Go step] in I/O-12 ~ I/O-14.
I/O? Seq select

Factory Default:
1
This code selects the sequence to set frequency,
transient time, steady speed time and motor direction the
steps.
I/O? Step number
52
2
Factory Default:
2
This code sets the number of steps to use for the
sequence number selected in I/O-51.
[Auto -A]
This mode will allow the inverter to operate automatically
followed by its pre-programmed sequence. According to
this sequence, eight different steps of Frequency,
Transient Time, Steady Speed time and Motor Direction
can be initiated with only a single multi-function input
contact closure (I/O-12 ~ I/O-14). The sequence and
steps are set in I/O-51 ~ I/O-84.
