ADJUSTMENT OF THE FREQUENCY SETTING POTENTIOMETER AND INDICATOR
(2) Adjusting a deviation of the highest frequency from the Pr. 38 (Pr. 39) setting.
(2)-1)Making adjustment with a voltage applied directly across terminals 2-5
(with a current flowing across terminals 4-5)
Changing example
Changing the calibration parameter C4 "frequency setting voltage gain"
POINT
The calibration parameter C4 is an extended function parameter. Pr. 30 must
be set to "1".
The frequency meter (indicator) connected to across terminals FM-SD does not
indicate just 50Hz ... Why?
The calibration parameter C1 "FM terminal calibration" value must be set.
(Refer to page 46.)
When write is performed, an error ( ) is displayed.
The gain and bias frequency settings are too close.
Turn the until " " appears.
