5-5-3 Adjusting the Analog Input
Input characteristic adjustments may be necessary for analog frequency
references
to be input. At that time, use the following parameters for gain,
bias, and filter time parameter adjustments.
H FR T erminal Adjustments for Frequency Reference Input
D Gain and Bias Settings (n41 and n42)
•Set the input characteristics of analog frequency references in n41 (for the frequency
reference gain) and n42 (for the frequency reference bias).
•Set the frequency of maximum analog input (10 V or 20 mA) in n41 as percentage
based on the maximum frequency as 100%.
•Set
the frequency of minimum analog input (0 V , 0 mA, or 4 mA) in n42 as percentage
based on the maximum frequency as 100%.

D Filter Time Constant Settings (n43)
•The digital filter with a first-order lag can be set for analog frequency references to be
input.
•This
setting is ideal if the analog input signal changes rapidly or the signal is subject to
noise interference.
•The larger the set value is, the slower the response speed will be.
