Adjusting [OI–L] characteristics
– In
the graph to the right, A103 and A104
select the active portion of the input
current range. Parameters A101 and A102
select the start and end frequency of the
converted output frequency range, respec-
tively. Together, these four parameters
define the major line segment as shown.
When the line does not begin at the origin
(A101 and A103 > 0), then A105 defines
whether the inverter outputs 0Hz or the
A101-specified frequency when the
analog input value is less than the A103
setting. When the input voltage is greater
than the A104 ending value, the inverter outputs the ending frequency specified by A102.
Adjusting [O2–L] characteristics
– In
the graph to the right, A113 and A114
select the active portion of the input
voltage range. Parameters A111 and
A112 select the start and end frequency of
the converted output frequency range,
respectively. Together, these four parame-
ters define the major line segment as
shown. When the input voltage is less
than the A113 input starting value, the
inverter outputs the starting frequency
specified by A111. When the input
voltage is greater than the A114 ending
value, the inverter outputs the ending
frequency specified by A112.
