Note
If n034 is set to a value less than the minimum output frequency (FMIN), the
Inverter will have no output when a frequency reference less than the minimum
output frequency input is ON.
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 reference 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, alter-
natively, the adjustments can be made by external analog voltage (cur-
rent), using the multi-function analog inputs.

Setting Frequency References by Analog Input
·
Analog inputs can be set only in remote mode. Set parameter n004 (frequency refer-
ence selection) to any of the following: 2 to 4 (frequency reference control terminal), 7
(multi-function analog voltage input), or 8 (multi-function analog current input).
Note
If the frequency reference control terminal is to be used for current inputs, the SW2 set-
ting must be changed from V to I. Please, also refer to page 2-17.

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 n41 as percentage
based on the maximum 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.
