(1) How to change the highest frequency
(2) Adjusting the deviation of the highest frequency from the Pr. 38 (Pr. 39) setting.
(2)-1) Make adjustment with a voltage applied directly across terminals 2-5 (with a
current flowing across terminals 4-5)
(2)-2) Make adjustment at any point without a voltage applied across terminals
2-5 (without a current flowing across terminals 4-5)
Changing example When you want to use the 0 to 5VDC input frequency setting
potentiometer to change the 5V frequency from 60Hz to 50Hz
POINT
Pr. 38 is an extended function parameter. Pr. 30 must be set to "1".
Change Pr. 38 "frequency setting voltage gain frequency" to 50Hz.
(1) How to change the highest frequency
Confirm the RUN indication and operation
mode indication.
The inverter must be at a stop.
The inverter must be in the PU operation mode.
(Press the key.)

3. Turn the setting dial until the
parameter number 38 "frequency
setting voltage gain frequency" appears.
Pr. 30 must be set to "1".
(For the Pr. 30 setting method, refer to
the instruction manual (basic).)
5. Turn the setting dial to change
the set value to "50.0". (50Hz)

By turning the setting dial , you can read another parameter.
Press the key to show the setting again.
Press the key twice to show the next parameter.
The monitor/frequency setting indication cannot be changed to just 50Hz
... Why?
The calibration parameter C4 "frequency setting voltage gain" value must
be set. (Refer to next page (2))
REMARKS
To change the value to more than 60Hz <50Hz>, Pr. 1 "maximum frequency" must
be set to more than 60Hz <50Hz>.
