<1> The setting F3-01 = 6 is enabled only when F3-03 = 2. Once enabled, the frequency reference can be set from 0.00
to 399.8 Hz with a BCD signal. Because the signed bit SI is also used, a negative reference cannot be input. The
smallest bit of the first digit starts with 2, so that 0.02 Hz is the smallest unit that can be used for the frequency
reference setting.
