Example 6:
In this example, a negative bias is used to provide a noise margin. Also a potentiometer frequency
gain is used to allow the Maximum Output Frequency to be reached.

Example 7:
This example with FWD/REV application can be easily used with system for the complicated
application. When this application is set, external FWD and REV command will auto be invalid.

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. With anti-slope enable, the large signal will slow or stop the AC drive.
Please notice that it can’t change the direction in this application, it only can change the AC drive to
reverse running.
