Configures the selection between frequency references 1 and 2
Set 0:
'40.23' setting value
The frequency is used by
'40.23'(ref 1 /ref 2 combination at PID disable)
set value
Set 1:
'40.22' setting value
The frequency is used by
'40.22'(ref source 2 at PID disable)
Set 2~9 : DI1~ DI8
If the digital input which is selected has OFF, it will applied by ref 1
If the digital input which is selected has ON, it will applied by ref 2
