 Bias/gain adjustment for digital inputs
 Bias adjustment
Bias adjustments can be made for the digital input signal.
Set the set frequency at the digital input signal of 0.
For BCD code input, set using Pr.300, and for binary input, set using Pr.302.
 Gain adjustment
Maximum output frequency (gain) adjustment can be made for the digital input signal.
Set the output frequency when the digital input signal is "999" or "9999" (BCD code input), or "HFFF" or "HFFFF" (binary input).
For BCD code input, set using Pr.301, and for binary input, set using Pr.303.
