Sets the gradient level and off-set value of the output frequency in
relation to the input voltage. These codes are displayed only when
In.06 is set to 1 (bipolar).
For example, if the ln.12 code is set to -2 V, In.13 code is set to 10%,
In.14 code is set to -8 V, and In.15 code is set to 80%, the output
frequency will vary within the range of 6–48 Hz.
For details about the 0–+10 V analog inputs, refer to the code
descriptions In.08 V1 volt x1–In.11 V1 Perc y2 on page 63.
