4.17.6 Frequency setting signal (current) bias/gain adjustment method
(a)Method to adjust any point by application of voltage (current) across the terminals 2 and 5 (4 and 5).
Perform the following procedure to adjust the bias and gain of the frequency setting voltage (current) using the
operation panel FR-DU07.
Refer to page 193 for the details of parameters.
REMARKS
⋅ If the frequency meter (indicator) connected to across terminals FM and SD does not indicate exactly 60Hz, set calibration
parameter C0 FM terminal calibration. (Refer to page 159)
⋅ If the gain and bias of frequency setting voltage (current) are too close, an error (
) may be displayed at setting.
