F E E 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 F E 1 : RR and
F E E
: IV, so to use the RX, PG or BIN
inputs, change the F E 1 or ■ F E E setting values to 3 ~ 5 •
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.
