Basic operation
4.6.4
Changing the frequency (60 Hz, initial value) at the maximum voltage input
(5 V, initial value)
Change the maximum frequency
Example
Changing example
With a 0 to 5 V DC input frequency setting potentiometer, change the frequency at 5 V from 60 Hz
(initial value) to 50 Hz.
Adjust the setting so that the inverter outputs 50 Hz when 5 V is input. Set "50 Hz" in Pr. 125.

NOTES
To set the frequency at 0 V, use the calibration parameter C2.
Other adjustment methods for the frequency setting voltage gain are the following: adjustment
by applying a voltage directly across terminals 2 and 5, and adjustment using a specified point
without applying a voltage across terminals 2 and 5.
