* If a signal is input into the selected
#1
frequency priority input, that value will be used as the actual
frequency reference. Even if a
signal is input into the selected #2 frequency priority input, the
#1
input
has priority. However, if the
#1
frequency priority input signal becomes 0, the #2 frequency priority input
will be used as the actual frequency reference.
The standard default settings are

By setting the analog input filter parameter I
I,-,
F
I,
a built-in filter constant can be configured to remove
noise
in
the input terminal voltage- and current-source frequency command signals. If stable operation is not
possible due to noise, increase the
filter time constant. The response will decrease, however, as the setting
value
is
increased.
