Pr.4-00 to Pr.4-03 are used when the source of frequency command is the analog signal (0 to
+10V DC or 4 to 20 mA DC). Refer to the following examples.
Example 1:
The following is the most common method. Set parameter 2-00 to d1 (0 to +10V signal) or d2 (4 to
20mA current signal).
Example 2:
In this example with the potentiometer set to 0V the Output Frequency is 10 Hz. The mid-point of
the potentiometer becomes 40 Hz. Once the Maximum Output Frequency is reached any further
increase of the potentiometer will not increase output frequency.
