Example 4: In this example a Process Signal range of 0 to 5 V is used to control the
output frequency from 0 to 60 Hz. Programming for this function can be done in two
ways: 1 set Pr.50 to 200%, 2 set Pr.03 to 120 Hz, Pr.50 to 100%.
Example 5: In this example Pr.49 is set to a 1 V Process Sigfnal bias and Pr.50 is set to
100% creating a potentiometer control voltage range of 1 to 10 V and an output
frequency range of 0 to 54 Hz. This configuration is suitable for high noise environments
where an external potentiometer is connected to the external AVI terminals by a cable.
Example 6: This example is a variation of Example 5. Set Pr.50 to 110% to extend the
maximum output frequency to 60 Hz. (In Example 5 the maximum output frequency is
54 Hz.)
