(4) Frequency setting signal (current) bias/gain adjustment method
(a)Method to adjust any point by application of voltage (current) across the terminals 2-5 (4-5).
REMARKS
⋅
If the frequency meter (indicator) connected to across terminals FM-SD does not indicate exactly 60Hz, set
calibration parameter
C0 FM terminal calibration
.
(Refer to page 138)
⋅
If the gain and bias of frequency setting voltage (current) are too close, an error (
) may be displayed at setting.
