PARAMETERS
(5) Frequency setting voltage (current) bias/gain adjustment method
(a)Method to adjust any point by application of voltage (current) to across the terminals 2 and 5 (4 and 5).
REMARKS
⋅ If the frequency meter (indicator) connected across terminals FM and SD does not indicate exactly 60Hz, set calibration
parameter C0 FM terminal calibration. (Refer to page 263)
⋅ If the gain and bias frequency settings are too close, an error ( ) may be displayed at the time of write.
