Example 7:
In this example, the potentiometer is programmed to run a motor is both forward and reverse
direction. A motor will be idle when the potentiometer position is at mid-point of its scale.
Using Pr.4-03 will disable the external FWD and REV controls.

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
