(3) Bias/gain adjustment [Pr. 300 to 303, 329]
For setting output frequency of when input signal is 0,
use [Pr. 300] for BCD code input, and use [Pr. 302] for
binary input.
For setting output frequency of maximum input signal
(999 or 9999 for BCD code input, and FFF
for binary input), use [Pr. 301] for BCD code input,
and use [Pr. 303] for binary input.

When "9999" is set in [Pr. 301] or [Pr. 303], the digital
input value is set as the output frequency (when [Pr.
329 = 1]). When this setting method is used, "bias"
setting ([Pr. 300] or [Pr. 302]) cannot be made.

When 9999 is set in [Pr. 301] or [Pr. 303], use [Pr. 329]
for changing the setting increments.
