Adjusting Frequency Gain Using an Analog Input
When H3-09 or H3-05 is set to 1 (frequency gain), you can adjust the frequency gain using the analog input
terminal A2 or A3.
The frequency gain for terminal A1 is the sum of H3-02 and terminal A2 gain. For example, when H3-02 is set
to 100% and terminal A2 is set to 5 V, the terminal A1 frequency reference will be 50%.
Setting Precautions
H3-05 cannot be set to 0.
Adjusting Frequency Bias Using an Analog Input
When parameter H3-09 or H3-05 is set to 0 (add to terminal A1), the frequency equivalent to the terminal A2
or A3 input voltage is added to A1 as a bias.
