Adjusting Analog Inputs: H3-02, H3-03, H3-06, H3-07, H3-10, H3-11, H3-12
D
There are three constants used to adjust the analog inputs: The gain, bias (both set separately for each
input), and filter time constant (a single value for all of the inputs).
•
The gain and bias can be adjusted separately for each analog input (terminals 36, 39, and 42).
Gain:
Set the frequency corresponding to a 10 V (20 mA) input as a percentage of the
maximum frequency. (The maximum output frequency set in E1-04 is 100%.)
Bias:
Set the frequency corresponding to a 0 V (4 mA) input as a percentage of the
maximum frequency. (The maximum output frequency set in E1-04 is 100%.)
•
Set the gains and biases for terminals 13, 14, and 16 as follows:

* The settings for terminal 42 are valid only when the multi-function analog input has been se-
lected. The gain and bias set here will be disregarded if a frequency reference is selected and
the values set for terminal 36 will be used.
