If an analog input supplies the frequency reference, make sure it produces the desired frequency reference. Make the
following adjustments if the drive does not operate as expected:
Gain adjustment: Set the maximum voltage/current signal and adjust the analog input gain (H3-03 for A1, H3-11 for A2,
H3-07 for A3) until the frequency reference value reaches the desired value.
Bias adjustment: Set the minimum voltage/current signal and adjust the analog input bias (H3-04 for A1, H3-12 for A2,
H3-08 for A3) until the frequency reference value reaches the desired minimum value.
