5.3.4 Change the frequency (40 Hz) of the maximum value of potentiometer (at 5 V)
쑶
Example
쑴
The frequency of the maximum analog voltage of the potentiometer (at 5 V) has to be changed
from the initial setting of 50 Hz to 40 Hz. Set 40 Hz in Pr. 125.

Fig. 5-28: Change the frequency of the maximum analog value
NOTES Set the frequency at 0 V using calibration parameter C2.
As other adjustment methods of frequency setting voltage gain, there are methods to adjust with
a voltage applied to across terminals 2-5 and adjust at any point without a voltage applied. (Refer
to section 6.16.3 for the setting method of calibration parameter C4.)
햲
Turn the digital dial until P.125 (Pr. 125) appears.

Press the SET key to show the currently set value.
The initial value "50.00" (50.00 Hz) appears.
햴
Turn the digital dial to change the set value to
