5-23

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
