Example 5:
In this example, a 5 Hz (10% of 50 Hz) negative bias is used. This setting
is used to provide a noise margin (1V in this example) in noisy environments.
Note that the top frequency is reduced to 45 Hz.

Example 6:
This example also uses negative bias and includes a potentiometer frequency
gain to allow the AC drive to reach the Maximum Output Frequency.

Example 7:
In this example, the potentiometer is programmed to run a motor in forward
or reverse direction. The motor will idle when the potentiometer is set at
the scale mid-point. Please note that this adjustment will disable the
external FWD and REV controls.

Example 8:
This example shows how to set up the "anti-slope", which is an inversely
proportional variation of frequency to the input analog signal, required
for some applications in process control. A sensor will generate a large
signal (such as 20mA or 10V) and the AC Drive will slow or stop.
