* 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.

By setting the analog input filter parameter 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.
