Chapter 4: AC Drive Parameters
Example 2: Positive Offset
In this example, the Analog Input will have a positive offset while still using the
full scale of the potentiometer. When the potentiometer is at its lowest value (0V,
0mA, or 4mA), the set-point frequency will be at 10Hz. When the potentiometer
is at its maximum value (10V or 20mA), the set-point frequency will be at 60Hz.
• Minimum Frequency Reference = 10Hz
• Maximum Frequency Reference = 60Hz
