5-6-3 Frequency Referencing by Analog Input
This section explains the methods for referencing frequencies by analog input, adjusting
input characteristics, and detecting input command errors. Either the frequency refer-
ence control terminal (voltage/current) or multi-function analog voltage/current input
can be used for analog inputs. The gain, bias, and filter time parameters can be used for
adjustments, or, alternatively, the adjustments can be made by external analog voltage
(current), using the multi-function analog inputs.
H Setting Frequency References by Analog Input
• Analog inputs can be set only in remote mode. Set parameter n004 (frequency reference selection) to
any of the following: 2 to 4 (frequency reference control terminal), 7 (multi-function analog voltage in-
put), or 8 (multi-function analog current input).
Note If the frequency reference control terminal is to be used for current inputs, the SW2 setting must
be changed from V to I.
H FR Terminal Adjustments for Frequency Reference Input
D Gain and Bias Settings (n060 and n061)
• Set the input characteristics of analog frequency references in n060 (for the frequency reference gain)
and n061 (for the frequency reference bias).
• Set the frequency of maximum analog input (10 V or 20 mA) in n060 as percentage based on the maxi-
mum frequency as 100%.
Example: In order to obtain the maximum frequency at 5 V, set the value to 200% because 10-V
input is 200% maximum frequency.
• Set the frequency of minimum analog input (0 V, 0 mA, or 4 mA) in n061 as percentage based on the
maximum frequency as 100%.
Example: In order to obtain 50% maximum frequency output with 0 V input, set the value to 50%.
• Use the following equation to obtain the reference value for the analog input value.
Reference value = {Analog input (%)  (Gain – Bias)}  Maximum frequency + Bias  Maximum
