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) (For the setting method,
refer to the instruction manual (detailed).)
Changing example
When you want to use the 0 to 5VDC input frequency setting
potentiometer to change the 5V-time frequency from 60Hz to
50Hz
POINT
• Pr. 38 is an extended function parameter. Pr. 30 must be set to "1".
(Refer to page 18.)
• Change Pr. 38 "frequency setting voltage gain frequency" to 50Hz.
1) Changing the highest frequency.
3.
Turn the setting dial until the
parameter number 38 "frequency
setting voltage gain frequency"
appears.

SET
Press the key to show the
currently set value. (60Hz)

MODE
Press the key to choose the
parameter setting mode.
Pr. 30 must be set to "1".
(For the parameter setting method,
refer to steps 3 to 6 on page 18.)
By turning the setting dial , you can read another parameter.
SET
Press the key to show the setting again.
SET
Press the key twice to show the next parameter.

previously
appears.
Operation
Display
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 page 23.)
Remarks
To change the value to more than 60Hz <50Hz>, Pr. 1 "maximum frequency"
must be set to more than 60Hz <50Hz>.
