Example 8:
In this example, the option of anti-slope is shown. Anti-slope is used in an application where
control of pressure, temperature, or flow is needed. Under a high pressure or flow situation,
a sensor will generate a large signal such as 20 mA or 10V. With anti-slope enable, the
large signal will slow or stop the AC drive
