This example gives 0Hz output through the first 0V~2.5V of Analog Input. The rest of the 2.5V~10V
corresponds to 0~45 Hz
• Minimum Frequency Reference = 0Hz
• Maximum Frequency Reference = 45Hz

NOTE: Due to the way Bias, Gain, and Reverse works, the graph above cannot be achieved with the
Bias and Gain settings: If Reverse is enabled (P4.09), the motor will run reverse when the signal goes
below 2.5V. If reverse is disabled, the analog value will be evaluated as an absolute value (what would
have been negative motion will now result in positive motion).

• Low Point = 0V input; 0Hz output; chart coordinates 0,0
• Mid Point = 2�5V input; 0Hz output; chart coordinates 2�5,0
• High Point = 10V input; 45Hz output; chart coordinates 10,45
NOTE: The Low/Mid/High Point method uses % output, instead of Hz. Therefore, the High Point value
in this example = 45Hz / 60Hz Max Output = 75%.
