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.
Operation
Parameter selection
Turn
until

Press
to enter the setting."
" and "
" flicker alternately.
Checking the mode/monitor
Press
three times to change to the monitor / frequency monitor.
#
Start
Turn ON the start switch (STF or STR), then turn the potentiometer (frequency setting potentiometer) clockwise slowly
to full. (Refer to steps
and
in section 4.6.3.) Operate at 50 Hz.
Tab. 4-18:
Change the frequency of the maximum analog value
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.
