Adjust the Input State using F2-02 and F2-03
The ratio (%) of the maximum output frequency that is output as the frequency reference
when the bias set by F2-03 is 0% is determined by the gain set by F2-02 and the combined
input signal.
Note:
For a single channel, a voltage input of 10 V or a current input of 20 mA is referred as 100%.
The gain set to parameter F2-02 along with the combined input signal determines the percentage
of maximum output frequency used as the frequency reference when the bias set to F2-03 is 0.
For a single channel, a voltage input of 0 V or a current input of 4 mA is referred as 100%.
Example 1
: If the gain in F2-02 is set to 50% and the bias in F2-03 is set to 0%, a combined
input signal of 100% yields a frequency reference 50% of the maximum frequency
reference. A combined input of 200% yields a frequency reference equal to the maximum
output frequency.
Example 2
: If the gain in F2-02 is set to 200% and the bias in F2-03 is set to 0%, a combined
input signal of 50% yields a frequency reference equal to the maximum output frequency.
Increasing the combined input signal of 50% or higher will not create a higher reference
since the maximum frequency reference has already been reached.
Example 3
: If the gain in F2-02 is set to 100% and the bias in F2-03 is set to 30%, a
combined input signal of 0% yields a frequency reference 30% of the maximum frequency
reference. Inputting a combined reference of 70% will yield a reference of equal to the
maximum output frequency. Increasing the combined input signal of 70% or higher will not
create a higher reference since the maximum frequency reference has already been reached.
