Figure 5.36 Output Frequency with Reduced Bias Setting
As a further example, for an inverse-acting speed command, set the bias = 100% and the gain = 0%. The minimum analog input level (0
Vdc or 4 mA) will produce a 100% speed command and the maximum analog input level (10 Vdc or 20 mA) will produce a 0% speed
command.
