Note
The range of the frequency reference given via communication is -10000 to 10000, corresponding
to -100.00% to 100.00%. -100.00% corresponds to the negative max. frequency, 0.00%
corresponds to the min. frequency, and 100.00% corresponds the max. frequency.
Suppose that F0-10 = 50 Hz, if the frequency reference in the write command is 1F40H, converted
to decimal 8000, the frequency reference that is written is 50 x 80.00% = 40 Hz.
