Explanation of functions (parameters)
<Setting>
(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
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.
