Example 2:
If you want the corresponded minimum value to be 12 Hz (the master frequency setting) when operating the
keypad potentiometer to the leftmost, and you set other frequency settings, refer to the diagram below. The
correspondence between the keypad potentiometer (voltage) and setting frequency has been changed from
0–5 V (min.–max.) / 0–60 Hz to 0–4 V / 0–60 Hz. Therefore, the 4 V and above from the keypad potentiometer
all correspond to 60 Hz. To use the full potentiometer range, refer to Example 3.
Example 3:
As shown in this example, the keypad potentiometer can be used for all ranges of 0–5 V / 0–60 Hz settings.
This increases flexibility.
Example 4:
This example shows how to use the first half range 0–2.5 V (min.–1/2 * max.) from the keypad potentiometer
to set 0–60 Hz frequency settings. You can achieve the same results by either adjusting Pr.04.02 gain or
setting Pr.01.00 to 120 Hz.
