figure.
6. 6. 3 Fine adjusting the analog frequency commands
<F470: RR input bias>
<F471: RR input gain>
<F472: RX input bias>
<F473: RX input gain>
<F474: II input bias>
<F475: II input gain>
<F476: AI4 input bias>
<F477: AI4 input gain>
<F478: AI5 input bias>
<F479: AI5 input gain>
■ Function
These parameters fine adjust the characteristics set in [6. 6. 2] "Setting frequency command
characteristics by analog signals".
Memo
• When you want to fine adjust the frequency command characteristics, adjust the bias and gain
of each input terminal at <F470: RR input bias>-<F479: AI5 input gain>. For details, refer to [6.
6. 3].
• When you want to set an analog signal for a frequency command, set at <FMOd: Frequency
command select 1> (or <F207: Frequency command select 2>).
1: Terminal RR
2: Terminal RX
3: Terminal II
4: Terminal AI4 (option)
5: Terminal AI5 (option)
