Any desired value of output frequency for frequency set value (0 to
10 V or 4 to 20 mA) can be set.
Example
Adjust so as to obtain 10% speed (6 Hz) at frequency setting volt-
age 0 V and 100% speed (60 Hz) at 8 V.

Note 1. The gain can be calculated using the following equations:
100 - b
x =
a
a: Setting voltage at 100% frequency
b: Bias level (%)
G: Gain set value
For example, if 100% speed (60 Hz) is obtained at 8 V, a=8. If
10% speed (6 Hz) is obtained at a frequency setting voltage of
0 V, b=10. In this case, the above equations yield G=1.23.
2. No. 22 and No. 23 can also be adjusted in DRIVE Mode.
