Chapter 6 - Parameter Description [I/O]
6-50
[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.

[AUTO B]
This mode can be also used to program up to 8 different
steps as Auto A. However, to switch from one step to
another, an external contact closure set to ‘Go step’ is
required.
