selection input: Frequency priority selection #1
selection input: Frequency priority selection #2
* 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

: RR and FEE : IV, so to use the RX, PG or BIN
inputs, change the F E 1 or

By setting the analog input filter parameter
I n I
a built-in fitter 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 fitter time constant. The response will decrease, however, as the setting
value is increased.
