8.4.2 Terminal IV
Terminal IV ( ) is a special terminal which is used in conjunction with
1st Function key
#5 to output exact frequencies based upon specific input
reference signals. These output frequencies do not necessarily have a one-to-
one ratio with the input reference signals. The following graphs and examples
illustrate how this function can be adjusted.

Input Signal
In the above graph the inverter has no output frequency until the input signal has reached 35%
of its maximum. This is due to the linear characteristics of the IV Function. Also notice that the
maximum frequency is reached before 100% of the input signal is applied.
Note:
In most cases the value of UL is less than FH.The value of UL cannot be greater than FH.
(F-P2) 60
(F-P1) 40
In the above graph the inverter has an output frequency of
20Hz even with a 0% input signal. Also notice that the
maximum output frequency is never reached unless the input
signal goes above 100%. (i.e. a 7Vdc input signal is consid-
ered a 140% input signal when using a 0~5Vdc input.

In the above graph the inverter has a negative output. In
other words, as the input signal increases the output
frequency decreases. Notice that at 0% and 100% input
the inverter outputs 60Hz and 0Hz, respectively.
