îš„Adjusting Analog Frequency Reference Using Constants
The frequency reference is input from the control circuit terminals using analog voltage and current.
If using frequency reference terminal A1 as an input terminal, perform adjustments using constants H3-02 and
H3-03. If using multi-function analog input terminal A2 as a frequency reference terminal, perform adjust-
ments using H3-10 and H3-11.

îš„Adjusting Frequency Gain Using an Analog Input
When H3-09 is set to 1 (frequency gain), you can adjust the frequency gain using the analog input
terminal A2 .
