Adjusting Frequency Gain Using an Analog Input
When
H3-09 is set to 1 (frequency gain), you can adjust the frequency gain using an analog input.
Fig 6.28 Frequency Gain Adjustment (Terminal A2 Input)
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%.
n
Adjusting Frequency Bias Using an Analog Input
When
parameter H3-09 is set to 0 (add to terminal A1), the frequency equivalent to the terminal A2 input volt-
age
is added to A1 as a bias.
